CHAPTER 1
Software development
1.1 System Requirements
GeoNetwork is a Java application that runs as a servlet so the Java Runtime Environment (JRE) must be installed in order to run it.
You can get the JRE from
http://www.oracle.com/technetwork/java/javase/downloads and you have to download the Java 6 Standard Edition (SE). GeoNetwork won’t run with Java 1.4. It will run with:
• Java 5 - but few people should be using that now as it is unsupported.
• Java 6 - most testing has taken place under Java 6, so we recommend Java 6.
• OpenJDK 7 - note: problems have been reported with OpenJDK 6.
Being written in Java, GeoNetwork can run on any platform that supports Java, so it can run on Windows,
Linux and Mac OSX. For MacOSX, make sure you use version 10.4 (Tiger) or newer. Version 10.3
(Panther) has only Java 1.4 so it cannot run GeoNetwork.
Next, you need a servlet container. GeoNetwork comes with an embedded container (Jetty) which is
fast and well suited for most applications. If you need a stronger one, you can install Tomcat from the
Apache Software Foundation (http://tomcat.apache.org). It provides load balancing, fault tolerance and
other production features. If you work for an organisation, it is probable that you already use Tomcat.
The tested version is 6.0.x but GeoNetwork should work with all other versions (>= 5.5).
Regarding storage, you need a Database Management System (DBMS) like Oracle, MySQL, Postgresql
etc. GeoNetwork comes with an embedded DBMS (H2) which is used by default during installation.
This DBMS can be used for small or desktop installations of no more than a few thousand metadata
records with one or two users. If you have heavier demands then you should use a professional, stand
alone DBMS.
GeoNetwork does not require a powerful machine. Good performance can be obtained even with 1GB
of RAM. The suggested amount is 2GB. For hard disk space, you have to consider the space required
for the application itself (about 350 MB) and the space required for data, which can require 50 GB
or more. A simple disk of 250 GB should be OK. You also need some space for the search index
which is located in GEONETWORK_DATA_DIR/index (by default GEONETWORK_DATA_DIR is
INSTALL_DIR/web/geonetwork/WEB_INF/data. However, even with a few thousand metadata records, the index is small so usually 500 MB of space is more than enough.
The software is run in different ways depending on the servlet container you are using:
3
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
• Tomcat - GeoNetwork is available as a WAR file which you can put into the Tomcat webapps
directory. Tomcat will deploy the WAR file when it is started. You can then use the Tomcat
manager web application to stop/start GeoNetwork. You can also use the startup.* and shutdown.*
scripts located in the Tomcat bin directory (.* means .sh or .bat depending on your OS) but if you
have other web applications in the tomcat container, then they will also be affected.
• Jetty - If you use the provided container you can use the scripts in GeoNetwork’s bin directory.
The scripts are start-geonetwork.* and stop-geonetwork.* and you must be inside the bin directory
to run them. You can use these scripts just after installation.
1.2 Tools
The following tools are required to be installed to setup a development environment for GeoNetwork:
• Java - Developing with GeoNetwork requires Java Development Kit (JDK) 1.6 or greater (scroll
down to find 1.6) OR the OpenJDK (version 7 or higher only) for Linux users.
• Maven - GeoNetwork uses Maven to manage the build process and the dependencies. Once is
installed, you should have the mvn command in your path (on Windows systems, you have to
open a shell to check).
• Git - GeoNetwork source code is stored and versioned in a Git repository on Github. Depending on your operating system a variety of git clients are avalaible. Check in http://gitscm.com/downloads/guis for some alternatives. Good documentation can be found on the git
website: http://git-scm.com/documentation and on the Github website https://help.github.com/.
• Ant - GeoNetwork uses Ant to build the installer. Version 1.6.5 works but any other recent version
should be OK. Once installed, you should have the ant command in your path (on Windows
systems, you have to open a shell to check).
• Sphinx - To create the GeoNetwork documentation in a nice format Sphinx is used.
1.3 Check out source code
If you just want to quickly get the code the fastest way is to download the zip bundle:
https://github.com/geonetwork/core-geonetwork/zipball/master
However, it is recommended that if you want to contribute back to Geonetwork you create a Github
account, fork the Geonetwork repository and work on your fork. This is a huge benefit because you
can push your changes to your repository as much as you want and when a feature is complete you can
make a ‘Pull Request’. Pull requests are the recommended method of contributing back to Geonetwork
because Github has code review tools and merges are much easier than trying to apply a patch attached
to a ticket.
The Geonetwork Repository is at: https://github.com/geonetwork/core-geonetwork.
Follow the instructions on the Github website to get started (make accounts, how to fork etc...)
http://help.github.com/
Once you have the repository forked or cloned locally you can begin to work.
A clone contains all branches so you can list the branches with:
4
Chapter 1. Software development
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
$ git branch -a
Just look at last section (ignoring remotes/origin/). To checkout a branch just:
$ git checkout 2.8.x
Typically work is done on branches and merged back so when developing normally you will go change
to the branch you want to work on, create a branch from there, work and then merge the changes back
(or make a Pull Request on Github). There are many great guides (See the links above) but here is a
quick sequence illustrating how to make a change and commit the change.
$ git checkout master
# master is the ’trunk’ and main development branch
# the checkout command "checks out" the requested branch
$ git checkout -b myfeature
# the -b requests that the branch be created
# ‘‘git branch‘‘ will list all the branches you have checked out locally at some poin
# ‘‘git branch -a‘‘ will list all branches in repository (checked out or not)
# work work work
$ git status
# See what files have been modified or added
$ git add <new or modified files>
# Add all files to be committed ‘‘git add -u‘‘ will add all modified (but not untrack
$ git commit
# Commit often. it is VERY fast to commit
# NOTE: doing a commit is a local operation. It does not push the change to Github
# more work
# another commit
$ git push origin myfeature
# this pushed your new branch to Github now you are ready to make a Pull Request to g
1.4 Build GeoNetwork
Once you checked out the code from Github repository, go inside the GeoNetwork’s root folder and
execute the maven build command:
$ mvn clean install
If the build is succesful you’ll get an output like:

Please refer to the maven documentation for any other options, Maven: The Complete Reference
1.4.1 Run embedded jetty server
Maven comes with built-in support for Jetty via a plug-in.
To run GeoNetwork with embedded jetty server you have to change directory to the root of the web
module, and then execute the following maven command:
$ mvn jetty:run
After a moment, GeoNetwork should be accessible at: http://localhost:8080/geonetwork
1.4.2 Source code documentation
The GeoNetwork Java source code is based on Javadoc. Javadoc is a tool for generating API documentation in HTML format from doc comments in source code. To see documentation generated by the
Javadoc tool, go to:
• GeoNetwork opensource Javadoc
1.4.3 User, developer and widget API documentation
Note: Building the GeoNetwork documentation requires the following be installed:
• Sphinx, version 0.6 or greater (sphinx-doc on ubuntu/debian)
• TeX Live (texlive-full on ubuntu/debian)
• make utility

Chapter 1. Software development
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
apt-get install texlive-full
easy_install Sphinx
easy_install JSTools
In order to build the documentation:
mvn clean install -Pwith-doc
1.5 Creating the installer
To run the build script that creates the installer you need the Ant tool. You can generate an installer by
running the ant command inside the installer directory:
$ ant
Buildfile: build.xml
setProperties:
...
BUILD SUCCESSFUL
Total time: 31 seconds
Both platform independent and Windows specific installers are generated by default.
Make sure you update version number and other relevant properties in the installer/build.xml
file
You can also create an installer that includes a Java Runtime Environment (JRE) for Windows. This will
allow GeoNetwork to run on a compatible, embedded JRE and thus avoid error messages caused by JRE
incompatibilities on the PC.
Creating an installer with an embedded JRE requires you to first download and unzip the JRE in a folder
jre1.5.0_12 at the project root level. Refer to the installer-config-win-jre.xml file for exact configuration.
1.6 Running tests
Build the application and run the integration tests in web-itests
$ mvn clean install -Pitests
1.6.1 Packaging GeoNetwork using Maven
Using Maven, you have the ability to package GeoNetwork in two different ways :
• WAR files (geonetwork.war, geoserver.war)
• Binary ZIP package (with Jetty embedded)
The Assembly Plugin is used to create the packages using
$ mvn package assembly:assembly
The Assembly Plugin configuration is in the release module (See bin.xml and zip-war.xml).

GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
1.7 Eclipse setup
The easiest way to develop geoNetwork within eclipse is with the m2e plugin, which comes by default
on many eclipse installations.
1.7.1 Import source code
In order to import the source code, follow instructions below :
• Press File> Import Menu item
• In new dialog Select Maven> Existing Maven Projects
• Press Next
• In Select root directory field enter where your code is:
• example: C:devgeonetworktrunk
• Select All projects and Press Finish button. If there appears another window, just continue without
changing any option.

Chapter 1. Software development
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
It will take some minutes while the m2e plugin downloads all the maven dependencies.
1.7.2 Debugging into eclipse
• JRebel Plugin :
Using the JRebel plugin is very useful for debugging on eclipse.
An example of the configuration file for JRebel may be the following:
<?xml version="1.0" encoding="UTF-8"?>
<application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.zer
<classpath>

1.7.3 Code Quality Tools in Eclipse
In order to see the same code quality warnings in eclipse as maven will detect, Find Bugs and Checkstyle
need to be installed in your eclipse install and configured as follows:
- Start Eclipse
- Go to **Help > Eclipse Marketplace**
- Install **findbugs**
- Don’t Restart
1.7. Eclipse setup
9
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
- Install **checkstyle**
- Now Restart
- Open preferences **Window > Preferences**
- Select *Java > Code Style > Code Templates*
- Select both Comments and Code elements
- Click **Import** and import **code_quality/codetemplates.xml**
- Select **Java > Code Style > Formatter**
- Click **Import** and import **code_quality/formatter.xml**
- Select **Java > Code Style > Clean Up**
- Click **Import** and import **code_quality/cleanup.xml**
- Select **Checkstyle**
- Click **New**
- Select **External Configuration**
- Enter any name (IE Geonetwork)
- For **location** choose **code_quality/checkstyle_checks.xml**
- Press *OK*
- Select New configuration
- Press *Set as Default*
- Select **Java > FindBugs**
- Set **analysis effort** to **Maximum**
- Set **Minimum rank to report** to **2**
- Set **Minimum confidence to report** to **Medium**
- Check(enable) all bug categories
- Set all **Mark bugs with ... rank as** to **Warning**
- Change to _Filter files_ tab
- Add **code_quality/findbugs-excludes.xml** file to the **Exclude filter files**
- Close Prefences
- Right click on project in **Projects View** select **Checkstyle > Activate Checkstyle
- Rebuild full project ( **Project > Clean...** )
- Checkstyle violations will show up as warnings
- Right click on project in **Projects View** select **Find Bugs > Find Bugs**
- FindBugs violations will show up as warnings
1.7.4 Code Quality Tools and Maven
During the build process FindBugs and Checkstyle are ran. If a violation is found then the build will
fail. Usually the easiest way of resolving violations are to use eclipse and run check style or find bugs
on the class or project with the failure. Usually a detailed report will be provided in eclipse along with
suggested fixes. If the violation is determined to be an intentional violation the code_quality/findbugsexcludes.xml or code_quality/checkstyle_suppressions.xml should be updated to suppress the reporting of the violation. (See Find Bugs and Checkstyle sections for more details.)
Since the FindBugs and Checkstyle processes can be quite time consuming adding -DskipTests to the
maven commandline will skip those processes as well as tests. For example:
mvn install -DskipTests
Or if you want to run the tests but skip static analysis:
mvn install -P-run-static-analysis
That disables the profile that executes the static analysis tasks.
10
Chapter 1. Software development
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
1.7.5 FindBugs
FindBugs is a tool that statically analyzes Java class files and searches for potential bugs. It excels
at finding issues like unclosed reasources, inconsistent locking of resources, refering null known nullvalues. It also checks for bad practices like using default platform charset instead of a explicit charset.
Because bad practices are checked for, sometimes Findbugs detects issues that are intentional. In order to account for these intentional violations Findbugs has exclude filter files which contain rules
for which violations should be ignored. In Geonetwork the excludes filter file can be found at
<root>/code_quality/findbugs-excludes.xml.
For complete details of how to specify matches in the excludes file
http://findbugs.sourceforge.net/manual/filter.html and look at the existing examples in the file.
see
The Maven build will fail if any violations are detected so it is important to run FindBugs on each project
and fix or exclude each violation that is reported.
1.7.6 FindBugs Annotations (JSR 305)
In order to get the maximum benefit from the Findbugs (and eclipse) analysis the javax.annotation annotations can be used to add metadata to methods, fields and parameters. The most commonly used
annotations are @CheckForNull and @Nonnull. These can be used on a parameter or return value to
indicate the parameter or return value must not be null or may be null. The findbugs process will enforce
these conditions and statically check that null is only ever correctly returned (in the case of return values)
or passed to a method (in the case of parameters).
Some resources for these annotations are:
• http://vard-lokkur.blogspot.ch/2012/03/findbugs-and-jsr-305.html
• http://www.infoq.com/news/2008/06/jsr-305-update

• http://minds.coremedia.com/2012/10/31/jsr-305-nonnull-and-guava-preconditions/
• http://findbugs.sourceforge.net/manual/annotations.html (the package names are outof date and
should be java.annotation instead of edu.umd.cs.findbugs.annotation but the descriptions are accurate)

CHAPTER 2
Create a release
This guide details the process of performing a release.
Note:
• BRANCH: Branches are created for major stables releases and end with .x (for example 2.8.x)
• VERSION (for tag): version to release (for example 2.8.1 or 2.8.1RC0)
2.1 Call for vote
In order to make a release ask the PSC to vote for the new release.
2.2 Release committee
To create new releases a committee of 2-4 persons should be chosen. The members of the committee
are responsible for creating the releases following the steps described in this section.
A rotation policy can be use to select a person from the committee who will be responsible for creating
each release.
2.3 Notify developer lists
It is good practice to notify the GeoNetwork developer list of the intention to make the release a few
days in advance.
On the day the release is being made a warning mail must be sent to the list asking that developers
refrain from committing until the release tag has been created.
2.4 Prerequisites
1. Commit access to GeoNetwork git
13
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
2. Administration rights to SourceForge server to publish the release
3. Administration rights to geonetwork-opensource.org to update the website (for stable release)
2.5 Add release to trac
Add the new version to the trac release list (http://trac.osgeo.org/geonetwork/admin/ticket/versions).
Add the 3 RC milestone (http://trac.osgeo.org/geonetwork/admin/ticket/milestones).
TODO: At some point, all open tickets for the master branch (eg. 2.9.0) should be moved
to the next RC (eg. 2.10.0RC1 or 2.10.1) or the next master (eg. 2.11.0).
2.6 Making the release
This procedure creates a new development branch and its first RC version.

CHAPTER 3
Harvesting
3.1 Structure
The harvesting capability is built around 3 areas: JavaScript code, Java code and XSL stylesheets (on
both the server and client side).
3.1.1 JavaScript code
This refers to the web interface. The code is located in the web/geonetwork/scripts/harvesting folder.
Here, there is a subfolder for each harvesting type plus some classes for the main page. These are:
1. harvester.js: This is an abstract class that must be implemented by harvesting types. It defines
some information retrieval methods (getType, getLabel, etc...) used to handle the harvesting type,
plus one getUpdateRequest method used to build the XML request to insert or update entries.
2. harvester-model.js: Another abstract class that must be implemented by harvesting types. When
creating the XML request, the only method substituteCommon takes care of adding common
information like privileges and categories taken from the user interface.
3. harvester-view.js: This is an important abstract class that must be implemented by harvesting
types. It takes care of many common aspects of the user interface. It provides methods to add
group’s privileges, to select categories, to check data for validity and to set and get common data
from the user interface.
4. harvesting.js: This is the main JavaScript file that takes care of everything. It starts all the submodules, loads XML strings from the server and displays the main page that lists all harvesting
nodes.
5. model.js: Performs all XML requests to the server, handles errors and decode responses.
6. view.js: Handles all updates and changes on the main page.
7. util.js: just a couple of utility methods.
3.1.2 Java code
The harvesting package is located in web/src/main/java/org/fao/geonet/kernel/harvest.
Here too, there is one subfolder for each harvesting type. The most important classes for the implemen19
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
tor are:
1. AbstractHarvester: This is the main class that a new harvesting type must extends. It takes care of
all aspects like adding, updating, removing, starting, stopping of harvesting nodes. Some abstract
methods must be implemented to properly tune the behaviour of a particular harvesting type.
2. AbstractParams: All harvesting parameters must be enclosed in a class that extends this abstract
one. Doing so, all common parameters can be transparently handled by this abstract class.
All others are small utility classes used by harvesting types.
3.1.3 XSL stylesheets
Stylesheets are spread in some folders and are used by both the JavaScript code and the server. The main
folder is located at web/src/webapp/xsl/harvesting. Here there are some general stylesheets,
plus one subfolder for each harvesting type. The general stylesheets are:
1. buttons.xsl: Defines all button present in the main page (activate, deactivate, run, remove, back,
add, refresh), buttons present in the “add new harvesting” page (back and add) and at the bottom
of the edit page (back and save).
2. client-error-tip.xsl: This stylesheet is used by the browser to build tooltips when an harvesting
error occurred. It will show the error class, the message and the stacktrace.
3. client-node-row.xsl: This is also used by the browser to add one row to the list of harvesting nodes
in the main page.
4. harvesting.xsl: This is the main stylesheet. It generates the HTML page of the main page and
includes all panels from all the harvesting nodes.
In each subfolder, there are usually 4 files:
1. xxx.xsl: This is the server stylesheets who builds all panels for editing the parameters. XXX is
the harvesting type. Usually, it has the following panels: site information, search criteria, options,
privileges and categories.
2. client-privil-row.xsl: This is used by the JavaScript code to add rows in the group’s privileges
panel.
3. client-result-tip.xsl: This is used by the JavaScript code (which inherits from harvester-view.js) to
show the tool tip when the harvesting has been successful.
4. client-search-row.xsl: Used in some harvesting types to generate the HTML for the search criteria
panel.
As you may have guessed, all client side stylesheets (those used by JavaScript code) start with the prefix
client-.
Another set of stylesheets are located in web/src/webapp/xsl/xml/harvesting and are used
by the xml.harvesting.get service. This service is used by the JavaScript code to retrieve all the nodes
the system is currently harvesting from. This implies that a stylesheet (one for each harvesting type)
must be provided to convert from the internal setting structure to an XML structure suitable to clients.
The last file to take into consideration contains all localised strings and is located at
web/src/webapp/loc/XX/xml/harvesting.xml (where XX refers to a language code). This
file is used by both JavaScript code and the server.
20
Chapter 3. Harvesting
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
3.2 Data storage
Harvesting nodes are stored inside the Settings table. Further useful information can be found in the
chapter Harvesting.
The SourceNames table is used to keep track of the uuid/name couple when metadata get migrated to
different sites.
3.3 Guidelines
To add a new harvesting type, follow these steps:
1. Add the proper folder in web/src/webapp/scripts/harvesting, maybe copying an already existing one.
2. Edit the harvesting.js file to include the new type (edit both constructor and init methods).
3. Add the proper folder in web/src/webapp/xsl/harvesting (again, it is easy to copy
from an already existing one).
4. Edit the stylesheet web/src/webapp/xsl/harvesting/harvesting.xsl and add the
new type
5. Add the transformation stylesheet in web/src/webapp/xsl/xml/harvesting. Its name
must match the string used for the harvesting type.
6. Add the Java code in a package inside org.fao.geonet.kernel.harvest.harvester.
7. Add proper strings in web/src/webapp/loc/XX/xml/harvesting.xml.
Here is a list of steps to follow when adding a new harvesting type:
1. Every harvesting node (not type) must generate its UUID. This UUID is used to remove metadata
when the harvesting node is removed and to check if a metadata (which has another UUID) has
been already harvested by another node.
2. If a harvesting type supports multiple searches on a remote site, these must be done sequentially
and results merged.
3. Every harvesting type must save in the folder images/logos a GIF image whose name is the node’s
UUID. This image must be deleted when the harvesting node is removed. This is necessary to
propagate harvesting information to other GeoNetwork nodes.
4. When a harvesting node is removed, all collected metadata must be removed too.
5. During harvesting, take in mind that a metadata could have been removed just after being added
to the result list. In this case the metadata should be skipped and no exception raised.
6. The only settable privileges are: view, dynamic, featured. It does not make sense to use the others.
7. If a node raises an exception during harvesting, that node will be deactivated.
8. If a metadata already exists (its UUID exists) but belong to another node, it must not be updated
even if it has been changed. This way the harvesting will not conflict with the other one. As a side
effect, this prevent locally created metadata from being changed.
9. The harvesting engine stores results in the database as part of the harvest history.
3.2. Data storage
21
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
10. When harvesting parameters are changed, the new harvesting type must use them during the next
harvesting without requiring server restart.

Metadata schemas and profiles
A metadata schema describes:
1. the names, descriptions and any value codelists of the elements in the metadata schema
2. how the elements of the metadata schema are laid out in a metadata document (structure)
3. constraints on elements and content in a metadata document
4. documentation on how the elements of the metadata schema should be used
5. sample metadata documents
6. scripts to convert metadata documents to and from other metadata schemas
A metadata schema is usually an implementation of a metadata standard.
A metadata profile is an adaptation of a metadata schema to suit the needs of a particular community. A
metadata profile contains all the components of a metadata schema but may extend, restrict or redefine
these components.

CHAPTER 6
Implementing a metadata schema or
profile
There are many ways in which a metadata schema or profile can be implemented. This section will
describe the way in which metadata schemas are implemented on https://github.com/metadata-schemas.
Each metadata schema is implemented as a filesystem tree. The root of the tree is the name of the
metadata schema in abbreviated form. The essential components of a metadata schema in this tree are
laid out as follows:
1. loc directory with subdirectories for each three letter language code that this information
is localized into, with the content in XML files (labels.xml, codelists.xml). For example:
loc/eng/codelists.xml describes the english codelists for metadata elements
2. schema directory and file named schema.xsd providing a single entry point to the XSD hierarchy.
For example: schema/gmd/gmd.xsd
3. schematron directory has constraints on elements and content in a metadata document implemented using the ISO schematron language
4. docs directory has documentation on how the elements of the metadata schema should be used.
5. sample-data directory has sample metadata documents
6. convert directory has XSLTs that convert metadata documents to and from other schemas
More information on the content of these directories and files will be given in the next section. Note:
some schemas on https://github.com/metadata-schemas have more information than described above
because they have been implemented as GeoNetwork schema plugins.

Chapter 6. Implementing a metadata schema or profile
CHAPTER 7
Schema Plugins
A schema plugin that can be used in GeoNetwork is a directory of stylesheets, XML schema descriptions
(XSDs) and other information necessary for GeoNetwork to index, view and possibly edit content from
XML metadata records.
To be used in GeoNetwork, a schema directory can be manually placed in the
config/schema_plugins sub directory of the geonetwork data directory. The default geonetwork
data directory location is INSTALL_DIR/web/geonetwork/WEB-INF/data. The contents of
these schemas are parsed during GeoNetwork initialization. If valid, they will be available for use when
GeoNetwork starts up.
Schemas can also added to GeoNetwork dynamically if a zip archive of the schema directory is created
and then uploaded to GeoNetwork in one of following ways using functions in the Administration menu:
1. Server file path (specified using file chooser)
2. HTTP URL (eg. http://somehost/somedirectory/iso19139.mcp.zip)
3. As an online resource attached to an ISO19115/19139 metadata record
Uploaded schemas are also stored in the config/schema_plugins sub directory of the geonetwork
data directory.
7.1 Contents of a GeoNetwork schema
When installed, a GeoNetwork schema is a directory.
The following subdirectories can be present:
• convert: (Mandatory) Directory of XSLTs to convert metadata from or to this schema. This could
be to convert metadata to other schemas or to convert metadata from other schemas and formats
to this schema. Eg. convert/oai_dc.xsl
• docs: (Mandatory) Directory of XSLTs to convert metadata from or to this schema. This could be
to convert metadata to other schemas or to convert metadata from other schemas and formats to
this schema. Eg. convert/oai_dc.xsl
• loc: (Mandatory) Directory of localized information: labels, codelists or schema specific strings.
Eg. loc/eng/codelists.xml
29
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
• present: (Mandatory) contains XSLTs for presenting metadata in the viewer/editor and in response to CSW requests for brief, summary and full records.
• process: (Optional) contains XSLTs for processing metadata elements by metadata suggestions
mechanism (see suggest.xsl below).
• sample-data: (Mandatory) Sample metadata for this schema. The metadata samples are in MEF
format so that samples can have thumbnails or browse graphics as well as online resources.
• schema: (Optional) Directory containing the official XSDs of the metadata schema. If the schema
is described by a DTD then this directory is optional. Note that schemas described by a DTD
cannot be edited by GeoNetwork.
• schematron: (Mandatory) Directory containing the schematrons used to check conditions on
content.
• templates: (Optional) Directory containing template and subtemplate metadata records for this
schema. Template metadata records are usually metadata records with the set of elements (and
content) that will be used for a specific purpose. Eg. iso19139.mcp schema has a ‘Minimum
Element’ template that has the mandatory elements for the schema and a example of the content
that is expected.
The following stylesheets can be present:
• extract-date-modified.xsl: (Mandatory) Extract the date of modification from the metadata
record.
• extract-gml.xsl: (Mandatory) Extract the spatial extent from the metadata record as a GML GeometryCollection element.
• extract-thumbnails.xsl: (Optional) Extract the browse graphic/thumbnail from the metadata
record.
• extract-uuid.xsl: (Mandatory) Extract the UUID of the metadata record.
• index-fields.xsl: (Mandatory) Index the metadata record content in Lucene. Creates the Lucene
document used by GeoNetwork to index the metadata record content.
• set-thumbnail.xsl: (Optional) Set the browse graphic/thumbnail in the metadata record.
• set-uuid.xsl: (Optional) Set the UUID of the metadata record.
• suggest.xsl: (Optional) XSLT run by metadata suggestions service. The XSLT contains
processes that can be registered and run on different elements of a metadata record. eg.
expand keyword field with comma separated content into multiple keyword fields. See
http://trac.osgeo.org/geonetwork/wiki/proposals/MetadataEditorSuggestion for more info.
• unset-thumbnail.xsl: (Optional) Remove the browse graphic/thumbnail from the metadata
record.
• update-child-from-parent-info.xsl: (Optional) XSLT to specify which elements in a child record
are updated from a parent record. Used to manage hierarchical relationships between metadata
records.
• update-fixed-info.xsl: (Optional) XSLT to update ‘fixed’ content in metadata records.
The following configuration files can be present:
• oasis-catalog.xml: (Optional) An oasis catalog describing any mappings that should be
used for this schema eg. mapping URLs to local copies such as schemaLocations eg.
http://www.isotc211.org/2005/gmd/gmd.xsd is mapped to schema/gmd/gmd.xsd. Path
30
Chapter 7. Schema Plugins
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
names used in the oasis catalog are relative to the location of this file which is the schema directory.
• schema.xsd: (Optional) XML schema directory file that includes the XSDs used by this metadata
schema. If the schema uses a DTD then this file should not be present. Metadata records from
schemas that use DTDs cannot be edited in GeoNetwork.
• schema-conversions.xml: (Optional) XML file that describes the converters that can be applied
to records belonging to this schema. This information is used to show these conversions as options
for the user to choose when a metadata record belonging to this schema is shown in the search
results.
• schema-ident.xml:
(Mandatory) XML file that contains the schema name,
identifier, version number and details on how to recognise metadata records
that belong to this schema.
This file has an XML schema definition in
INSTALL_DIR/web/geonetwork/xml/validation/schemaPlugins/schema-ident.xsd
which is used to validate it when the schema is loaded.
• schema-substitutes.xml: (Optional) XML file that redefines the set of elements that can be used
as substitutes for a specific element.
• schema-suggestions.xml: (Optional) XML file that tells the editor which child elements of a
complex element to automatically expand in the editor.
To help in understanding what each of these components is and what is required, we will now give a
step-by-step example of how to build a schemaPlugin for GeoNetwork.
7.2 Preparation
In order to create a schema plugin for GeoNetwork, you should check out the schemaPlugins directory
from the GeoNetwork sourceforge subversion repository. You can do this by installing subversion on
your workstation and then executing the following command:
svn co https://github.com/geonetwork/schema-plugins/branches/2.8.x schemaPlugins
This will create a directory called schemaPlugins with some GeoNetwork schema plugins in it. To
work with the example shown here, you should create your new schema plugin in a subdirectory of this
directory.
7.3 Example - ISO19115/19139 Marine Community Profile (MCP)
The Marine Community Profile (MCP) is a profile of ISO19115/19139 developed for and with the Marine Community. The profile extends the ISO19115 metadata standard and is implemented using an
extension of the XML implementation of ISO19115 described in ISO19139. Both the ISO19115 metadata standard and its XML implementation, ISO19139, are available through ISO distribution channels.
The
documentation
for
the
Marine
Community
Profile
can
be
found
at
http://www.aodc.gov.au/files/MarineCommunityProfilev1.4.pdf.
The implementation of the Marine Community Profile as XML schema definitions is based on the approach described at
https://www.seegrid.csiro.au/wiki/AppSchemas/MetadataProfiles.
The XML schema definitions
(XSDs) are available at the URL http://bluenet3.antcrc.utas.edu.au/mcp-1.4.
7.2. Preparation
31
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
Looking at the XML schema definitions, the profile adds a few new elements to the base ISO19139
standard. So the basic idea in defining a plugin Marine Community Profile schema for GeoNetwork is
to use as much of the basic ISO19139 schema definition supplied with GeoNetwork as possible.
We’ll now describe in basic steps how to create each of the components of a plugin schema for GeoNetwork that implements the MCP.
7.3.1 Creating the schema-ident.xml file
Now we need to provide the information necessary to identify the schema and metadata records that
belong to the schema. The schema-ident.xml file for the MCP is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://geonetwork-opensource.org/schemas/schema-ident"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
.....>
<name>iso19139.mcp</name>
<id>19c9a2b2-dddb-11df-9df4-001c2346de4c</id>
<version>1.5</version>
<schemaLocation>
http://bluenet3.antcrc.utas.edu.au/mcp
http://bluenet3.antcrc.utas.edu.au/mcp-1.5-experimental/schema.xsd

http://www.isotc211.org/2005/srv
http://schemas.opengis.net/iso/19139/20060504/srv/srv.xsd
</schemaLocation>
<autodetect xmlns:mcp="http://bluenet3.antcrc.utas.edu.au/mcp"
xmlns:gmd="http://www.isotc211.org/2005/gmd"
xmlns:gco="http://www.isotc211.org/2005/gco">
<elements>
<gmd:metadataStandardName>
<gco:CharacterString>

</gco:CharacterString>
</gmd:metadataStandardVersion>
</elements>
</autodetect>
</schema>
Each of the elements is as follows:
• name - the name by which the schema will be known in GeoNetwork. If the schema is a profile of a base schema already added to GeoNetwork then the convention is to call the schema
<base_schema_name>.<namespace_of_profile>.
• id - a unique identifier for the schema.
• version - the version number of the schema. Multiple versions of the schema can be present in
32
Chapter 7. Schema Plugins
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
GeoNetwork.
• schemaLocation - a set of pairs, where the first member of the pair is a namespace URI
and the second member is the official URL of the XSD. The contents of this element will be
added to the root element of any metadata record displayed by GeoNetwork as a schemaLocation/noNamespaceSchemaLocation attribute, if such as attribute does not already exist. It will
also be used whenever an official schemaLocation/noNamespaceSchemaLocation is required (eg.
in response to a ListMetadataFormats OAI request).
• autodetect - contains elements or attributes (with content) that must be present in any metadata
record that belongs to this schema. This is used during schema detection whenever GeoNetwork
receives a metadata record of unknown schema.
After creating this file you can validate it manually using the XML schema definition (XSD) in
INSTALL_DIR/web/geonetwork/xml/validation/schemaPlugins/schema-ident.xsd.
This XSD is also used to validate this file when the schema is loaded. If schema-ident.xml failes
validation, the schema will not be loaded.
More on autodetect
The autodetect section of schema-ident.xml is used when GeoNetwork needs to identify which metadata
schema a record belongs to.
The five rules that can be used in this section in order of evaluation are:
1. Attributes - Find one or more attributes and/or namespaces in the document. An example
use case is a profile of ISO19115/19139 that adds optional elements under a new namespace to
gmd:identificationInfo/gmd:MD_DataIdentification. To detect records that belong to this profile the
autodetect section in the schema-ident.xml file could look something like the following:
<autodetect xmlns:cmar="http://www.marine.csiro.au/schemas/cmar.xsd">
<!-- catch all cmar records that have the cmar vocab element -->
<attributes cmar:vocab="http://www.marine.csiro.au/vocabs/projectCodes.xml"/>
</autodetect>
Some other points about attributes autodetect:
• multiple attributes can be specified - all must be match for the record to be recognized as belonging
to this schema.
• if the attributes have a namespace then the namespace should be specified on the autodetect element or somewhere in the schema-ident.xml document.
2. Elements - Find one or more elements in the document. An example use case is the one shown in the
example schema-ident.xml file earlier:
<autodetect xmlns:mcp="http://bluenet3.antcrc.utas.edu.au/mcp"
xmlns:gmd="http://www.isotc211.org/2005/gmd"
xmlns:gco="http://www.isotc211.org/2005/gco">

1.5-experimental|
MCP:BlueNet V1.5-experimental|
MCP:BlueNet V1.5
</gco:CharacterString>
</gmd:metadataStandardVersion>
</elements>
</autodetect>
Some other points about elements autodetect:
• multiple elements can be specified - eg. as in the above, both metadataStandardName and metadataStandardVersion have been specified - all must be match for the record to be recognized as
belonging to this schema.
• multiple values for the elements can be specified. eg. as in the above, a match for
gmd:metadataStandardVersion will be found for 1.5-experimental OR MCP:BlueNet
V1.5-experimental OR MCP:BlueNet V1.5 - the vertical line or pipe character ‘|’ is
used to separate the options here.
• if the elements have a namespace then the namespace(s) should be specified on the autodetect
element or somewhere in the schema-ident.xml document before the element in which they are
used - eg. in the above there are there namespace declarations on the autodetect element so as not
to clutter the content.
3. Root element - root element of the document must match. An example use case is the one used for
the eml-gbif schema. Documents belonging to this schema always have root element of eml:eml so the
autodetect section for this schema is:
<autodetect xmlns:eml="eml://ecoinformatics.org/eml-2.1.1">
<elements type="root">
<eml:eml/>
</elements>
</autodetect>
Some other points about root element autodetect:
• multiple elements can be specified - any element in the set that matches the root element of the
record will trigger a match.
• if the elements have a namespace then the namespace(s) should be specified on the autodetect
element or somewhere in the schema-ident.xml document before the element that uses them - eg.
as in the above there is a namespace declaration on the autodetect element for clarity.
4. Namespaces - Find one or more namespaces in the document. An example use case is the one
used for the csw:Record schema. Records belonging to the csw:Record schema can have three possible
root elements: csw:Record, csw:SummaryRecord and csw:BriefRecord, but instead of using a multiple
element root autodetect, we could use the common csw namespace for autodetect as follows:
<autodetect>
<namespaces xmlns:csw="http://www.opengis.net/cat/csw/2.0.2"/>
</autodetect>
Some other points about namespaces autodetect:
• multiple namespaces can be specified - all must be present for the record to be recognized as
belonging to this schema.
34
Chapter 7. Schema Plugins
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
• the prefix is ignored. A namespace match occurs if the namespace URI found in the record
matches the namespace URI specified in the namespaces autodetect element.
5. Default schema - This is the fail-safe provision for records that don’t match any of the installed schemas. The value for the default schema is specified in the appHandler configuration
of the INSTALL_DIR/web/geonetwork/WEB-INF/config.xml config file or it could be a
default specified by the operation calling autodetect (eg. a value parsed from a user bulk loading some metadata records). For flexibility and accuracy reasons it is preferable that records
be detected using the autodetect information of an installed schema. The default schema is
just a ‘catch all’ method of assigning records to a specific schema. The config element in
INSTALL_DIR/web/geonetwork/WEB-INF/config.xml looks like the following:
<appHandler class="org.fao.geonet.Geonetwork">
.....
<param name="preferredSchema" value="iso19139" />
.....
</appHandler>
More on autodetect evaluation
The rules for autodetect are evaluated as follows:
for-each autodetect rule type in ( ’attributes/namespaces’, ’elements’,
’namespaces’, ’root element’ )
for-each schema
if schema has autodetect rule type then
check rule for a match
if match add to list of previous matches
end if
end for-each
if more than one match throw ’SCHEMA RULE CONFLICT EXCEPTION’
if one match then set matched = first match and break loop
end for-each
if no match then
if namespaces of record and default schema overlap then
set match = default schema
else throw ’NO SCHEMA MATCHES EXCEPTION’
end if
return matched schema
As an example, suppose we have three schemas iso19139.mcp, iso19139.mcp-1.4 and iso19139.mcpcmar with the following autodetect elements:
iso19139.mcp-1.4:
<autodetect xmlns:mcp="http://bluenet3.antcrc.utas.edu.au/mcp"
xmlns:gmd="http://www.isotc211.org/2005/gmd"
xmlns:gco="http://www.isotc211.org/2005/gco">
<elements>
<gmd:metadataStandardName>
<gco:CharacterString>
Australian Marine Community Profile of ISO 19115:2005/19139
</gco:CharacterString>

</gmd:metadataStandardName>
<gmd:metadataStandardVersion>

</elements>
</autodetect>
iso19139.mcp-cmar:
<autodetect>
<attributes xmlns:mcp-cmar="http://www.marine.csiro.au/schemas/mcp-cmar">
</autodetect>
iso19139.mcp:
<autodetect xmlns:mcp="http://bluenet3.antcrc.utas.edu.au/mcp">
<elements type="root">
<mcp:MD_Metadata/>
</elements>
</autodetect>
A record going through autodetect processing (eg. on import) would be checked against:
• iso19139.mcp-cmar first as it has an ‘attributes’ rule
• then iso19139.mcp-1.4 as it has an ‘elements’ rules
• then finally against iso19139.mcp, as it has a ‘root element’ rule.
The idea behind this processing algorithm is that base schemas will use a ‘root element’ rule (or the
more difficult to control ‘namespaces’ rule) and profiles will use a finer or more specific rule such as
‘attributes’ or ‘elements’.
After setting up schema-ident.xml, our new GeoNetwork plugin schema for MCP contains:
schema-ident.xml
7.3.2 Creating the schema-conversions.xml file
This file describes the converters that can be applied to metadata records that belong to the schema. Each
converter must be manually defined as a GeoNetwork (Jeeves) service that can be called to transform
a particular metadata record to a different schema. The schema-conversions.xml file for the MCP is as
follows:
<conversions>
<converter name="xml_iso19139.mcp"
nsUri="http://bluenet3.antcrc.utas.edu.au/mcp"
schemaLocation="http://bluenet3.antcrc.utas.edu.au/mcp-1.5-experimental/sc
xslt="xml_iso19139.mcp.xsl"/>
<converter name="xml_iso19139.mcp-1.4"
nsUri="http://bluenet3.antcrc.utas.edu.au/mcp"
schemaLocation="http://bluenet3.antcrc.utas.edu.au/mcp/schema.xsd"
xslt="xml_iso19139.mcp-1.4.xsl"/>
<converter name="xml_iso19139.mcpTooai_dc"
nsUri="http://www.openarchives.org/OAI/2.0/"
schemaLocation="http://www.openarchives.org/OAI/2.0/oai_dc.xsd"
xslt="oai_dc.xsl"/>
<converter name="xml_iso19139.mcpTorifcs"
36
Chapter 7. Schema Plugins
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
nsUri="http://ands.org.au/standards/rif-cs/registryObjects"
schemaLocation="http://services.ands.org.au/home/orca/schemata/registryObj
xslt="rif.xsl"/>
</conversions>
Each converter has the following attributes:
• name - the name of the converter. This is the service name of the GeoNetwork (Jeeves) service
and should be unique (prefixing the service name with xml_<schema_name> is a good way to
make this name unique).
• nsUri - the primary namespace of the schema produced by the converter.
eg.
xml_iso19139.mcpTorifcs transforms metadata records from iso19139.mcp to the RIFCS
schema. Metadata records in the RIFCS metadata schema have primary namespace URI of
http://ands.org.au/standards/rif-cs/registryObjects.
• schemaLocation - the location (URL) of the XML schema definition (XSD) corresponding to the
nsURI.
• xslt - the name of the XSLT that actually carries out the transformation. This XSLT should be
located in the convert subdirectory of the schema plugin.
After setting up schema-conversions.xml, our new GeoNetwork plugin schema for MCP contains:
schema-conversions.xml
schema-ident.xml
7.3.3 Creating the schema directory and schema.xsd file
The schema and schema.xsd components are used by the GeoNetwork editor and validation functions.
GeoNetwork’s editor uses the XSDs to build a form that will not only order the elements in a metadata
document correctly but also offer options to create any elements that are not in the metadata document.
The idea behind this approach is twofold. Firstly, the editor can use the XML schema definition rules
to help the user avoid creating a document that is structurally incorrect eg. missing mandatory elements
or elements not ordered correctly. Secondly, the same editor code can be used on any XML metadata
document with a defined XSD.
If you are defining your own metadata schema then you can create an XML schema document using the XSD language.
The elements of the language can be found online at
http://www.w3schools.com/schema/ or you can refer to a textbook such as Priscilla Walmsley’s Definitive XML Schema (Prentice Hall, 2002). GeoNetwork’s XML schema parsing code understands almost
all of the XSD language with the exception of redefine, any and anyAttribute (although the last two can
be handled under special circumstances).
In the case of the Marine Commuity Profile, we are basically defining a number of extensions to the base
standard ISO19115/19139. These extensions are defined using the XSD extension mechanism on the
types defined in ISO19139. The following snippet shows how the Marine Community Profile extends
the gmd:MD_Metadata element to add a new element called revisionDate:
<xs:schema targetNamespace="http://bluenet3.antcrc.utas.edu.au/mcp"
xmlns:mcp="http://bluenet3.antcrc.utas.edu.au/mcp" .....>
....
<xs:element name="MD_Metadata" substitutionGroup="gmd:MD_Metadata"
type="mcp:MD_Metadata_Type"/>
7.3. Example - ISO19115/19139 Marine Community Profile (MCP)
37
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
<xs:complexType name="MD_Metadata_Type">
<xs:annotation>
<xs:documentation>
Extends the metadata element to include revisionDate
</xs:documentation>
</xs:annotation>
<xs:complexContent>
<xs:extension base="gmd:MD_Metadata_Type">
<xs:sequence>
<xs:element name="revisionDate" type="gco:Date_PropertyType"
minOccurs="0"/>
</xs:sequence>
<xs:attribute ref="gco:isoType" use="required"
fixed="gmd:MD_Metadata"/>
</xs:extension>
</xs:complexContent>
</xs:complexType>
</xs:schema>
In short, we have defined a new element mcp:MD_Metadata with type mcp:MD_Metadata_Type, which
is an extension of gmd:MD_Metadata_Type. By extension, we mean that the new type includes all of the
elements of the old type plus one new element, mcp:revisionDate. A mandatory attribute (gco:isoType)
is also attached to mcp:MD_Metadata with a fixed value set to the name of the element that we extended
(gmd:MD_Metadata).
By defining the profile in this way, it is not necessary to modify the underlying ISO19139 schemas.
So the schema directory for the MCP essentially consists of the extensions plus the base ISO19139
schemas. One possible directory structure is as follows:
extensions
gco
gmd
gml
gmx
gsr
gss
gts
resources
srv
xlink
The extensions directory contains a single file mcpExtensions.xsd, which imports the gmd namespace.
The remaining directories are the ISO19139 base schemas.
The schema.xsd file, which is the file GeoNetwork looks for, will import the mcpExtensions.xsd file and
any other namespaces not imported as part of the base ISO19139 schema. It is shown as follows:
<xs:schema targetNamespace="http://bluenet3.antcrc.utas.edu.au/mcp"
elementFormDefault="qualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:mcp="http://bluenet3.antcrc.utas.edu.au/mcp"
xmlns:gmd="http://www.isotc211.org/2005/gmd"
xmlns:gmx="http://www.isotc211.org/2005/gmx"
xmlns:srv="http://www.isotc211.org/2005/srv">
<xs:include schemaLocation="schema/extensions/mcpExtensions.xsd"/>
<!-- this is a logical place to include any additional schemas that are
related to ISO19139 including ISO19119 -->
<xs:import namespace="http://www.isotc211.org/2005/srv"
schemaLocation="schema/srv/srv.xsd"/>
<xs:import namespace="http://www.isotc211.org/2005/gmx"
schemaLocation="schema/gmx/gmx.xsd"/>
</xs:schema>
At this stage, our new GeoNetwork plugin schema for MCP contains:

schema-ident.xml

7.3.4 Creating the extract-... XSLTs
GeoNetwork needs to extract certain information from a metadata record and translate it into a common,
simplified XML structure that is independent of the metadata schema. Rather than do this with Java
coded XPaths, XSLTs are used to process the XML and return the common, simplified XML structure.
The three xslts we’ll create are:
• extract-date-modified.xsl - this XSLT processes the metadata record and extracts the date the
metadata record was last modified. For the MCP, this information is held in the mcp:revisionDate
element which is a child of mcp:MD_Metadata. The easiest way to create this for MCP is to copy
extract-date-modified.xsl from the iso19139 schema and modify it to suit the MCP namespace and
to use mcp:revisionDate in place of gmd:dateStamp.
• extract-gml.xsl - this XSLT processes the metadata record and extracts the spatial extent as a gml
GeometryCollection element. The gml is passed to geotools for insertion into the spatial index
(either a shapefile or a spatial database). For ISO19115/19139 and profiles, this task is quite easy
because spatial extents (apart from the bounding box) are encoded as gml in the metadata record.
Again, the easiest way to create this for the MCP is to copy extract-gml.xsd from the iso19139
schema ad modify it to suit the MCP namespace.
An example bounding box fragment from an MCP metadata record is:
<gmd:extent>
<gmd:EX_Extent>
<gmd:geographicElement>
<gmd:EX_GeographicBoundingBox>
<gmd:westBoundLongitude>
<gco:Decimal>112.9</gco:Decimal>
</gmd:westBoundLongitude>
<gmd:eastBoundLongitude>
<gco:Decimal>153.64</gco:Decimal>
</gmd:eastBoundLongitude>
<gmd:southBoundLatitude>
<gco:Decimal>-43.8</gco:Decimal>
</gmd:southBoundLatitude>
<gmd:northBoundLatitude>
<gco:Decimal>-9.0</gco:Decimal>
</gmd:northBoundLatitude>
</gmd:EX_GeographicBoundingBox>
</gmd:geographicElement>
</gmd:EX_Extent>
</gmd:extent>
Running extract-gml.xsl on the metadata record that contains this XML will produce:
<gml:GeometryCollection xmlns:gml="http://www.opengis.net/gml">
<gml:Polygon>
<gml:exterior>
<gml:LinearRing>
<gml:coordinates>
112.9,-9.0, 153.64,-9.0, 153.64,-43.8, 112.9,-43.8, 112.9,-9.0
</gml:coordinates>
</gml:LinearRing>
7.3. Example - ISO19115/19139 Marine Community Profile (MCP)
39
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
</gml:exterior>
</gml:Polygon>
</gml:GeometryCollection>
If there is more than one extent in the metadata record, then they should also appear in this
gml:GeometryCollection element.
To find out more about gml, see Lake, Burggraf, Trninic and Rae, “GML Geography Mark-Up Language, Foundation for the Geo-Web”, Wiley, 2004.
Finally, a note on projections. It is possible to have bounding polygons in an MCP record in a projection
other than EPSG:4326. GeoNetwork transforms all projections known to GeoTools (and encoded in
a form that GeoTools understands) to EPSG:4326 when writing the spatial extents to the shapefile or
spatial database.
• extract-uuid.xsl - this XSLT processes the metadata record and extracts the identifier for the
record. For the MCP and base ISO standard, this information is held in the gmd:fileIdentifier
element which is a child of mcp:MD_Metadata.
These xslts can be tested by running them on a metadata record from the schema. You should use the
saxon xslt processor. For example:
java -jar INSTALL_DIR/web/geonetwork/WEB-INF/lib/saxon-9.1.0.8b-patch.jar
-s testmcp.xml -o output.xml extract-gml.xsl
At this stage, our new GeoNetwork plugin schema for MCP contains:
extract-date-modified.xsl extract-gml.xsd
extract-uuid.xsl
schema-conversions.xml schema-ident.xml schema.xsd schema
7.3.5 Creating the localized strings in the loc directory
The loc directory contains localized strings specific to this schema, arranged by language abbreviation
in sub-directories.
You should provide localized strings in whatever languages you expect your schema to be used in.
Localized strings for this schema can be used in the presentation xslts and schematron error messages.
For the presentation xslts:
• codelists for controlled vocabulary fields should be in loc/<language_abbreviation>/codelists.xml
eg. loc/eng/codelists.xml
• label strings that replace XML element names with more intelligible/alternative phrases
and rollover help strings should be in loc/<language_abbreviation>/labels.xml eg.
loc/eng/labels.xml.
• all other localized strings should be in loc/<language_abbreviation>/strings.xml eg.
loc/eng/strings.xml
Note that because the MCP is a profile of ISO19115/19139 and we have followed the GeoNetwork
naming convention for profiles, we need only include the labels and codelists that are specific to the
MCP or that we want to override. Other labels and codelists will be retrieved from the base schema
iso19139.

More on codelists.xml
Typically codelists are generated from enumerated lists in the metadata schema XSDs such as the following from http://www.isotc211.org/2005/gmd/identification.xsd for gmd:MD_TopicCategoryCode in
the iso19139 schema:
<xs:element name="MD_TopicCategoryCode" type="gmd:MD_TopicCategoryCode_Type"/>
<xs:simpleType name="MD_TopicCategoryCode_Type">
<xs:restriction base="xs:string">

</codelist>
The codelists.xml file maps the enumerated values from the XSD to a localized label and a description
via the code element.
A localized copy of codelists.xml is made available on an XPath to the presentation XSLTs eg.
/root/gui/schemas/iso19139/codelist for the iso19139 schema.
The XSLT metadata.xsl which contains templates used by all metadata schema presentation XSLTs,
handles the creation of a select list/drop down menu in the editor and display of the code and description
in the metadata viewer.
The iso19139 schema has additional codelists that are managed external to the XSDs in catalog/vocabulary files such as http://www.isotc211.org/2005/resources/Codelist/gmxCodelists.xml These
have also been added to the codelists.xml file so that they can be localized, overridden in profiles and
include an extended description to provide more useful information when viewing the metadata record.
The iso19139 schema has additional templates in its presentation xslts to handlese codelists because
they are specific to that schema. These are discussed in the section on presentation XSLTs later in this
manual.
More on labels.xml
A localized copy of labels.xml is made available on an XPath to the presentation XSLTs eg.
/root/gui/schemas/iso19139/labels for the iso19139 schema.
The labels.xml file can also be used to provide helper values in the form of a drop down/select list
for free text fields. As an example:
<element name="gmd:credit" id="27.0">
<label>Credit</label>
<description>Recognition of those who contributed to the resource(s)</description>
<helper>
<option value="University of Tasmania">UTAS</option>
<option value="University of Queensland">UQ</option>
</helper>
</element>
This would result in the Editor (through the XSLT metadata.xsl) displaying the credit field with these
helper options listed beside it in a drop down/select menu something like the following:
More on strings.xml
A localized copy of strings.xml is made available on an XPath to the presentation XSLTs eg.
/root/gui/schemas/iso19139/strings for the iso19139 schema.

After adding the localized strings, our new GeoNetwork plugin schema for MCP contains:

loc present schema-conversions.xml schema-ident.xml schema.xsd
schema
7.3.6 Creating the presentations XSLTs in the present directory
Each metadata schema should contain XSLTs that display and possibly edit metadata records that belong
to the schema. These XSLTs are held in the present directory.
To be be used in the XSLT include/import hierarchy these XSLTs must follow a naming convention: metadata-<schema-name>.xsl. So for example, the presentation xslt for the iso19139 schema is
metadata-iso19139.xsl. For the MCP, since our schema name is iso19139.mcp, the presentation
XSLT would be called metadata-iso19193.mcp.xsl.
Any XSLTs included by the presentation XSLT should also be in the present directory (this is a convention for clarity - it is not mandatory as include/import URLs can be mapped in the oasis-catalog.xml for
the schema to other locations).
There are certain XSLT templates that the presentation XSLT must have:
• the main template, which must be called: metadata-<schema-name>. For the MCP profile of iso19139 the main template would look like the following (taken from metadataiso19139.mcp.xsl):
<xsl:template name="metadata-iso19139.mcp">
<xsl:param name="schema"/>
<xsl:param name="edit" select="false()"/>
<xsl:param name="embedded"/>
<xsl:apply-templates mode="iso19139" select="." >
<xsl:with-param name="schema" select="$schema"/>
<xsl:with-param name="edit"
select="$edit"/>
<xsl:with-param name="embedded" select="$embedded" />
</xsl:apply-templates>
</xsl:template>
Analyzing this template:
1. The name=”metadata-iso19139.mcp” is used by the main element processing template in metadata.xsl: elementEP. The main metadata services, show and edit, end up calling metadata-show.xsl
and metadata-edit.xsl respectively with the metadata record passed from the Java service. Both
these XSLTs, process the metadata record by applying the elementEP template from metadata.xsl
to the root element. The elementEP template calls this main schema template using the schema
name iso19139.mcp.
2. The job of this main template is set to process all the elements of the metadata record using
templates declared with a mode name that matches the schema name or the name of the base
schema (in this case iso19139). This modal processing is to ensure that only templates intended to
process metadata elements from this schema or the base schema are applied. The reason for this
is that almost all profiles change or add a small number of elements to those in the base schema.
So most of the metadata elements in a profile can be processed in the mode of the base schema.
We’ll see later in this section how to override processing of an element in the base schema.

GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
• a completeTab template, which must be called: <schema-name>CompleteTab. This template will
display all tabs, apart from the ‘default’ (or simple mode) and the ‘XML View’ tabs, in the left
hand frame of the editor/viewer screen. Here is an example for the MCP:
<xsl:template name="iso19139.mcpCompleteTab">
<xsl:param name="tabLink"/>
<xsl:call-template name="displayTab"> <!-- non existent tab - by profile -->
<xsl:with-param name="tab"
select="’’"/>
<xsl:with-param name="text"
select="/root/gui/strings/byGroup"/>
<xsl:with-param name="tabLink" select="’’"/>
</xsl:call-template>
<xsl:call-template name="displayTab">
<xsl:with-param name="tab"
select="’mcpMinimum’"/>
<xsl:with-param name="text"
select="/root/gui/strings/iso19139.mcp/mcpMinimum"/>
<xsl:with-param name="indent" select="’&#xA0;&#xA0;&#xA0;’"/>
<xsl:with-param name="tabLink" select="$tabLink"/>
</xsl:call-template>
<xsl:call-template name="displayTab">
<xsl:with-param name="tab"
select="’mcpCore’"/>
<xsl:with-param name="text"
select="/root/gui/strings/iso19139.mcp/mcpCore"/>
<xsl:with-param name="indent" select="’&#xA0;&#xA0;&#xA0;’"/>
<xsl:with-param name="tabLink" select="$tabLink"/>
</xsl:call-template>
<xsl:call-template name="displayTab">
<xsl:with-param name="tab"
select="’complete’"/>
<xsl:with-param name="text"
select="/root/gui/strings/iso19139.mcp/mcpAll"/>
<xsl:with-param name="indent" select="’&#xA0;&#xA0;&#xA0;’"/>
<xsl:with-param name="tabLink" select="$tabLink"/>
</xsl:call-template>
...... (same as for iso19139CompleteTab in
GEONETWORK_DATA_DIR/schema_plugins/iso19139/present/
metadata-iso19139.xsl) ......
</xsl:template>
This template is called by the template named “tab” (which also adds the “default” and “XML
View” tabs) in INSTALL_DIR/web/geonetwork/xsl/metadata-tab-utils.xsl using
the schema name. That XSLT also has the code for the “displayTab” template.
‘mcpMinimum’, ‘mcpCore’, ‘complete’ etc are the names of the tabs. The name of the current or active
tab is stored in the global variable “currTab” available to all presentation XSLTs. Logic to decide what
to display when a particular tab is active should be contained in the root element processing tab.
• a root element processing tab. This tab should match on the root element of the metadata record.
For example, for the iso19139 schema:
<xsl:template mode="iso19139" match="gmd:MD_Metadata">
<xsl:param name="schema"/>
<xsl:param name="edit"/>
<xsl:param name="embedded"/>
<xsl:choose>
44
Chapter 7. Schema Plugins
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
<!-- metadata tab -->
<xsl:when test="$currTab=’metadata’">
<xsl:call-template name="iso19139Metadata">
<xsl:with-param name="schema" select="$schema"/>
<xsl:with-param name="edit"
select="$edit"/>
</xsl:call-template>
</xsl:when>
<!-- identification tab -->
<xsl:when test="$currTab=’identification’">
<xsl:apply-templates mode="elementEP" select="gmd:identificationInfo|geonet:child[st
<xsl:with-param name="schema" select="$schema"/>
<xsl:with-param name="edit"
select="$edit"/>
</xsl:apply-templates>
</xsl:when>
.........
</xsl:template>
This template is basically a very long “choose” statement with “when” clauses that test the value of
the currently defined tab (in global variable currTab). Each “when” clause will display the set of
metadata elements that correspond to the tab definition using “elementEP” directly (as in the “when”
clause for the ‘identification’ tab above) or via a named template (as in the ‘metadata’ tab above). For
the MCP our template is similar to the one above for iso19139, except that the match would be on
“mcp:MD_Metadata” (and the processing mode may differ - see the section ‘An alternative XSLT design for profiles’ below for more details).
• a brief template, which must be called: <schema-name>Brief. This template processes the metadata record and extracts from it a format neutral summary of the metadata for purposes such as
displaying the search results. Here is an example for the eml-gbif schema (because it is fairly
short!):
<xsl:template match="eml-gbifBrief">
<xsl:for-each select="/metadata/*[1]">
<metadata>
<title><xsl:value-of select="normalize-space(dataset/title[1])"/></title>
<abstract><xsl:value-of select="dataset/abstract"/></abstract>
<xsl:for-each select="dataset/keywordSet/keyword">
<xsl:copy-of select="."/>
</xsl:for-each>
<geoBox>
<westBL><xsl:value-of select="dataset/coverage/geographicCoverage/boundingCoordi
<eastBL><xsl:value-of select="dataset/coverage/geographicCoverage/boundingCoordi
<southBL><xsl:value-of select="dataset/coverage/geographicCoverage/boundingCoord
<northBL><xsl:value-of select="dataset/coverage/geographicCoverage/boundingCoord
</geoBox>
<xsl:copy-of select="geonet:info"/>
</metadata>
</xsl:for-each>
</xsl:template>
Analyzing this template:
1. The template matches on an element eml-gbifBrief, created by the mode=”brief” template in
7.3. Example - ISO19115/19139 Marine Community Profile (MCP)
45
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
metadata-utils.xsl. The metadata record will be the first child in the /metadata XPath.
2. Then process metadata elements to produce a flat XML structure that is used by search-resultsxhtml.xsl to display a summary of the metadata record found by a search.
Once again, for profiles of an existing schema, it makes sense to use a slighlty different approach so that
the profile need not duplicate templates. Here is an example from metadata-iso19139.mcp.xsl:
<xsl:template match="iso19139.mcpBrief">
<metadata>
<xsl:for-each select="/metadata/*[1]">
<!-- call iso19139 brief -->
<xsl:call-template name="iso19139-brief"/>
<!-- now brief elements for mcp specific elements -->
<xsl:call-template name="iso19139.mcp-brief"/>
</xsl:for-each>
</metadata>
</xsl:template>
This template splits the processing between the base iso19139 schema and a brief template that handles
elements specific to the profile. This assumes that:
1. The base schema has separated the <metadata> element from the remainder of its brief processing
so that it can be called by profiles
2. The profile includes links to equivalent elements that can be used by the base schema to
process common elements eg. for ISO19139, elements in the profile have gco:isoType attributes that give the name of the base element and can be used in XPath matches such as
“gmd:MD_DataIdentification|*[@gco:isoType=’gmd:MD_DataIdentification’]”.
• templates that match on elements specific to the schema. Here is an example from the eml-gbif
schema:
<!-- keywords are processed to add thesaurus name in brackets afterwards
in view mode -->
<xsl:template mode="eml-gbif" match="keywordSet">
<xsl:param name="schema"/>
<xsl:param name="edit"/>
<xsl:choose>
<xsl:when test="$edit=false()">
<xsl:variable name="keyword">
<xsl:for-each select="keyword">
<xsl:if test="position() &gt; 1">, </xsl:if>
<xsl:value-of select="."/>
</xsl:for-each>
<xsl:if test="keywordThesaurus">
<xsl:text> (</xsl:text>
<xsl:value-of select="keywordThesaurus"/>
<xsl:text>)</xsl:text>
</xsl:if>
</xsl:variable>
<xsl:apply-templates mode="simpleElement" select=".">
<xsl:with-param name="schema" select="$schema"/>
<xsl:with-param name="edit"
select="$edit"/>
<xsl:with-param name="text"
select="$keyword"/>
</xsl:apply-templates>
</xsl:when>
46
Chapter 7. Schema Plugins
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
<xsl:otherwise>
<xsl:apply-templates mode="complexElement" select=".">
<xsl:with-param name="schema" select="$schema"/>
<xsl:with-param name="edit"
select="$edit"/>
</xsl:apply-templates>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
Analyzing this template:
1. In view mode the individual keywords from the set are concatenated into a comma separated string
with the name of the thesaurus in brackets at the end.
2. In edit mode, the keywordSet is handled as a complex element ie. the user can add individual
keyword elements with content and a single thesaurus name.
3. This is an example of the type of processing that can be done on an element in a metadata record.
For profiles, templates for elements can be defined in the same way except that the template will process
in the mode of the base schema. Here is an example showing the first few lines of a template for
processing the mcp:revisionDate element:
<xsl:template mode="iso19139" match="mcp:revisionDate">
<xsl:param name="schema"/>
<xsl:param name="edit"/>
<xsl:choose>
<xsl:when test="$edit=true()">
<xsl:apply-templates mode="simpleElement" select=".">
<xsl:with-param name="schema" select="$schema"/>
<xsl:with-param name="edit"
select="$edit"/>
......
If a template for a profile is intended to override a template in the base schema, then the template can
be defined in the presentation XSLT for the profile with a priority attribute set to a high number and an
XPath condition that ensures the template is processed for the profile only. For example in the MCP, we
can override the handling of gmd:EX_GeographicBoundingBox in metadata-iso19139.xsl by defining a
template in metadata-iso19139.mcp.xsl as follows:
<xsl:template mode="iso19139" match="gmd:EX_GeographicBoundingBox[starts-with(//geonet:i
......
Finally, a profile may also extend some of the existing codelists in the base schema. These extended
codelists should be held in a localized codelists.xml. As an example, in iso19139 these codelists are
often attached to elements like the following:
<gmd:role>
<gmd:CI_RoleCode codeList="http://www.isotc211.org/2005/resources/Codelist/gmxCodelist
</gmd:role>
Templates for handling these elements are in the iso19139 presentation XSLT
GEONETWORK_DATA_DIR/schema_plugins/iso19139/present/metadata-iso19139.xsl.
These templates use the name of the element (eg. gmd:CI_RoleCode) and the codelist XPath (eg.
/root/gui/schemas/iso19139/codelists) to build select list/drop down menus when editing and to display
7.3. Example - ISO19115/19139 Marine Community Profile (MCP)
47
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
a full description when viewing. See templates near the template named ‘iso19139Codelist’. These
templates can handle the extended codelists for any profile because they:
• match on any element that has a child element with attribute codeList
• use the schema name in the codelists XPath
• fall back to the base iso19139 schema if the profile codelist doesn’t have the required codelist
However, if you don’t need localized codelists, it is often easier and more direct to extract codelists
directly from the gmxCodelists.xml file. This is in fact the solution that has been adopted for the
MCP. The gmxCodelists.xml file is included in the presentation xslt for the MCP using a statement
like:
<xsl:variable name="codelistsmcp"
select="document(’../schema/resources/Codelist/gmxCodelists.xml’)"/>
Check the codelist handling templates in metadata-iso19139.mcp.xsl to see how this works.
An alternative XSLT design for profiles
In all powerful languages there will be more than one way to achieve a particular goal. This alternative XSLT design is for processing profiles. The idea behind the alternative is based on the following
observations about the GeoNetwork XSLTs:
1. All elements are initially processed by apply-templates in mode “elementEP”.
2. The template “elementEP” (see INSTALL_DIR/web/geonetwork/xsl/metadata.xsl)
eventually calls the main template of the schema/profile.
3. The main template can initially process the element in a mode particular to the profile and if this
is not successful (ie. no template matches and thus no HTML elements are returned), process the
element in the mode of the base schema.
The advantage of this design is that overriding a template for an element in the base schema does not
need the priority attribute or an XPath condition check on the schema name.
Here is an example for the MCP (iso19139.mcp) with base schema iso19139:
• the main template, which must be called: metadata-iso19139.mcp.xsl:
<!-- main template - the way into processing iso19139.mcp -->
<xsl:template name="metadata-iso19139.mcp">
<xsl:param name="schema"/>
<xsl:param name="edit" select="false()"/>
<xsl:param name="embedded"/>
<!-- process in profile mode first -->
<xsl:variable name="mcpElements">
<xsl:apply-templates mode="iso19139.mcp" select="." >
<xsl:with-param name="schema" select="$schema"/>
<xsl:with-param name="edit"
select="$edit"/>
<xsl:with-param name="embedded" select="$embedded" />
</xsl:apply-templates>
</xsl:variable>
<xsl:choose>
<!-- if we got a match in profile mode then show it -->
48
Chapter 7. Schema Plugins
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
<xsl:when test="count($mcpElements/*)>0">
<xsl:copy-of select="$mcpElements"/>
</xsl:when>
<!-- otherwise process in base iso19139 mode -->
<xsl:otherwise>
<xsl:apply-templates mode="iso19139" select="." >
<xsl:with-param name="schema" select="$schema"/>
<xsl:with-param name="edit"
select="$edit"/>
<xsl:with-param name="embedded" select="$embedded" />
</xsl:apply-templates>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
Analyzing this template:
1. The name=”metadata-iso19139.mcp” is used by the main element processing template in metadata.xsl: elementEP. The main metadata services, show and edit, end up calling metadata-show.xsl
and metadata-edit.xsl respectively with the metadata record passed from the Java service. Both
these XSLTs, process the metadata record by applying the elementEP template from metadata.xsl
to the root element. elementEP calls the appropriate main schema template using the schema
name.
2. The job of this main template is set to process all the elements of the metadata profile. The
processing takes place in one of two modes. Firstly, the element is processed in the profile mode
(iso19139.mcp). If a match is found then HTML elements will be returned and copied to the
output document. If no HTML elements are returned then the element is processed in the base
schema mode, iso19139.
• templates that match on elements specific to the profile have mode iso19139.mcp:
<xsl:template mode="iso19139.mcp" match="mcp:taxonomicElement">
<xsl:param name="schema"/>
<xsl:param name="edit"/>
.....
</xsl:template>
• templates that override elements in the base schema are processed in the profile mode
iso19139.mcp
<xsl:template mode="iso19139.mcp" match="gmd:keyword">
<xsl:param name="schema"/>
<xsl:param name="edit"/>
.....
</xsl:template>
Notice that the template header of the profile has a simpler design than that used for the original design?
Neither the priority attribute or the schema XPath condition is required because we are using a different
mode to the base schema.
• To support processing in two modes we need to add a null template to the profile mode
iso19139.mcp as follows:
7.3. Example - ISO19115/19139 Marine Community Profile (MCP)
49
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
<xsl:template mode="iso19139.mcp" match="*|@*"/>
This template will match all elements that we don’t have a specific template for in the profile mode
iso19139.mcp. These elements will be processed in the base schema mode iso19139 instead because the
null template returns nothing (see the main template discussion above).
The remainder of the discussion in the original design relating to tabs etc applies to the alternative design
and is not repeated here.
CSW Presentation XSLTs
The CSW server can be asked to provide records in a number of output schemas. The two supported by
GeoNetwork are:
• ogc - http://www.opengis.net/cat/csw/2.0.2 - a dublin core derivative
• iso - http://www.isotc211.org/2005/gmd - ISO19115/19139
From each of these output schemas, a brief, summary or full element set can be requested.
These output schemas and element sets are implemented in GeoNetwork as XSLTs and they are stored
in the ‘csw’ subdirectory of the ‘present’ directory. The ogc output schema XSLTs are implemented
as ogc-brief.xsl, ogc-summary and ogc-full.xsl. The iso output schema XSLTs are implemented as isobrief.xsl, iso-summary.xsl and iso-full.xsl.
To create these XSLTs for the MCP, the best option is to copy and modify the csw presentation XSLTs
from the base schema iso19139.
After creating the presentation XSLTs, our new GeoNetwork plugin schema for MCP contains:
extract-date-modified.xsl extract-gml.xsd extract-uuid.xsl
loc present schema-conversions.xml schema-ident.xml schema.xsd

7.3.7 Creating the index-fields.xsl to index content from the metadata record
This XSLT indexes the content of elements in the metadata record. The essence of this XSLT is to select
elements from the metadata record and map them to lucene index field names. The lucene index field
names used in GeoNetwork are as follows:

<Field name="changeDate" string="{string(.)}" store="true" index="true"/>
</xsl:for-each>
Notice that we are creating a new XML document. The Field elements in this document are read by
GeoNetwork to create a Lucene document object for indexing (see the SearchManager class in the
GeoNetwork source).
Once again, because the MCP is a profile of ISO19115/19139, it is probably best to modify
index-fields.xsl from the schema iso19139 to handle the namespaces and additional elements
of the MCP.
At this stage, our new GeoNetwork plugin schema for MCP contains:
extract-date-modified.xsl extract-gml.xsd extract-uuid.xsl
index-fields.xsl loc present schema-conversions.xml schema-ident.xml
schema.xsd schema
7.3.8 Creating the sample-data directory
This is a simple directory. Put MEF files with sample metadata in this directory. Make sure they have a
.mef suffix.
7.3. Example - ISO19115/19139 Marine Community Profile (MCP)
51
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
A MEF file is a zip archive with the metadata, thumbnails, file based online resources and an info file
describing the contents. The contents of a MEF file are discussed in more detail in the next section of
this manual.
Sample data in this directory can be added to the catalog using the Administration menu.
At this stage, our new GeoNetwork plugin schema for MCP contains:
extract-date-modified.xsl extract-gml.xsd extract-uuid.xsl
index-fields.xsl loc present sample-data schema-ident.xml
schema
schema.xsd
7.3.9 Creating schematrons to describe MCP conditions
Schematrons are rules that are used to check conditions and content in the metadata record as part of the
two stage validation process used by GeoNetwork.
Schematron rules are created in the schematrons directory that you checked out earlier - see Preparation
above.
An example rule is:
<!-- anzlic/trunk/gml/3.2.0/gmd/spatialRepresentation.xsd-->
<!-- TEST 12 -->
<sch:pattern>
<sch:title>$loc/strings/M30</sch:title>
<sch:rule context="//gmd:MD_Georectified">
<sch:let name="cpd" value="(gmd:checkPointAvailability/gco:Boolean=’1’ or gmd:checkP
(not(gmd:checkPointDescription) or count(gmd:checkPointDescription[@gco:nilReason=
<sch:assert
test="$cpd = false()"
>$loc/strings/alert.M30</sch:assert>
<sch:report
test="$cpd = false()"
>$loc/strings/report.M30</sch:report>
</sch:rule>
</sch:pattern>
As for most of GeoNetwork, the output of this rule can be localized to different languages. The corresponding localized strings are:
<strings>
.....
<M30>[ISOFTDS19139:2005-TableA1-Row15] - Check point description required if available
.....
<alert.M30><div>’checkPointDescription’ is mandatory if ’checkPointAvailability’ = 1 o
.....
<report.M30>Check point description documented.</report.M30>
.....
</strings>
52
Chapter 7. Schema Plugins
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
Procedure for adding schematron rules, working within the schematrons directory:
1. Place your schematron rules in ‘rules’. Naming convetion is ‘schematron-rules-<suffix>.sch’
eg. schematron-rules-iso-mcp.sch. Place localized strings for the rule assertions into
‘rules/loc/<language_prefix>’.
2. Edit build.xml.
3. Add a “clean-schema-dir” target for your plugin schema directory. This target will remove
the schematron rules from plugin schema directory (basically removes all files with pattern
schematron-rules-*.xsl).
4. Add a “compile-schematron” target for your rules - value attribute is the suffix used in the rules
name. eg. for schematron-rules-iso-mcp.sch the value attribute should be “iso-mcp”.
This target will turn the .sch schematron rules into an XSLT using the saxon XSLT engine and
‘resources/iso_svrl_for_xslt2.xsl’.
5. Add a “publish-schematron” target. This target copies the compiled rules (in XSLT form) into the
plugin schema directory.
6. Run ‘ant’ to create the schematron XSLTs.
At this stage, our new GeoNetwork plugin schema for MCP contains:
extract-date-modified.xsl extract-gml.xsd extract-uuid.xsl
index-fields.xsl loc present sample-data schema-conversions.xml
schema-ident.xml schema.xsd schema schematron-rules-iso-mcp.xsl
7.3.10 Adding the components necessary to create and edit MCP metadata
So far we have added all the components necessary for GeoNetwork to identify, view and validate
MCP metadata records. Now we will add the remaining components necessary to create and edit MCP
metadata records.
We’ll start with the XSLTs that set the content of various elements in the MCP metadata records.
Creating set-uuid.xsl
• set-uuid.xsl - this XSLT takes as a parameter the UUID of the metadata record and writes it into
the appropriate element of the metadata record. For the MCP this element is the same as the base
ISO schema (called iso19139 in GeoNetwork), namely gmd:fileIdentifier. However, because the
MCP uses a different namespace on the root element, this XSLT needs to be modified.
Creating the extract, set and unset thumbnail XSLTs
If your metadata record can have a thumbnail or browse graphic link, then you will want to add XSLTs
that extract, set and unset this information so that you can use the GeoNetwork thumbnail editing interface.
The three XSLTs that support this interface are:
• extract-thumbnails.xsl - this XSLT extracts the thumbnails/browse graphics from the metadata
record, turning it into generic XML that is the same for all metadata schemas. The elements need
to have content that GeoNetwork understands. The following is an example of what the thumbnail
interface for iso19139 expects (we’ll duplicate this requirement for MCP):
7.3. Example - ISO19115/19139 Marine Community Profile (MCP)
53
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
<gmd:graphicOverview>
<gmd:MD_BrowseGraphic>
<gmd:fileName>
<gco:CharacterString>bluenet_s.png</gco:CharacterString>
</gmd:fileName>
<gmd:fileDescription>
<gco:CharacterString>thumbnail</gco:CharacterString>
</gmd:fileDescription>
<gmd:fileType>
<gco:CharacterString>png</gco:CharacterString>
</gmd:fileType>
</gmd:MD_BrowseGraphic>
</gmd:graphicOverview>
<gmd:graphicOverview>
<gmd:MD_BrowseGraphic>
<gmd:fileName>
<gco:CharacterString>bluenet.png</gco:CharacterString>
</gmd:fileName>
<gmd:fileDescription>
<gco:CharacterString>large_thumbnail</gco:CharacterString>
</gmd:fileDescription>
<gmd:fileType>
<gco:CharacterString>png</gco:CharacterString>
</gmd:fileType>
</gmd:MD_BrowseGraphic>
</gmd:graphicOverview>
When extract-thumbnails.xsl is run, it creates a small XML hierarchy from this information
which looks something like the following:
<thumbnail>
<large>
bluenet.png
</large>
<small>
bluenet_s.png
</small>
</thumbnail>
• set-thumbnail.xsl - this XSLT does the opposite of extract-thumbnails.xsl. It takes the simplified,
common XML structure used by GeoNetwork to describe the large and small thumbnails and
creates the elements of the metadata record that are needed to represent them. This is a slightly
more complex XSLT than extract-thumbnails.xsl because the existing elements in the metadata
record need to be retained and the new elements need to be created in their correct places.
• unset-thumbnail.xsl - this XSLT targets and removes elements of the metadata record that describe a particular thumbnail. The remaining elements of the metadata record are retained.
Because the MCP is a profile of ISO19115/19139, the easiest path to creating these XSLTs is to copy
them from the iso19139 schema and modify them for the changes in namespace required by the MCP.
Creating the update-... XSLTs
• update-child-from-parent-info.xsl - this XSLT is run when a child record needs to have content
copied into it from a parent record. It is an XSLT that changes the content of a few elements and
54
Chapter 7. Schema Plugins
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
leaves the remaining elements untouched. The behaviour of this XSLT would depend on which
elements of the parent record will be used to update elements of the child record.
• update-fixed-info.xsl - this XSLT is run after editing to fix certain elements and content in the
metadata record. For the MCP there are a number of actions we would like to take to ‘hard-wire’
certain elements and content. To do this the XSLT the following processing logic:
if the element is one that we want to process then
add a template with a match condition for that element and process it
else copy the element to output
Because the MCP is a profile of ISO19115/19139, the easiest path to creating this XSLT is to copy
update-fixed-info.xsl from the iso19139 schema and modify it for the changes in namespace required by
the MCP and then to include the processing we want.
A simple example of MCP processing is to make sure that the gmd:metadataStandardName and
gmd:metadataStandardVersion elements have the content needed to ensure that the record is recognized
as MCP. To do this we can add two templates as follows:
<xsl:template match="gmd:metadataStandardName" priority="10">
<xsl:copy>
<gco:CharacterString>Australian Marine Community Profile of ISO 19115:2005/19139</gc
</xsl:copy>
</xsl:template>
<xsl:template match="gmd:metadataStandardVersion" priority="10">
<xsl:copy>
<gco:CharacterString>MCP:BlueNet V1.5</gco:CharacterString>
</xsl:copy>
</xsl:template>
Processing by update-fixed-info.xsl can be enabled/disabled using the Automatic Fixes check
box in the System Configuration menu. By default, it is enabled.
Some important tasks handled in upgrade-fixed-info.xsl:
• creating URLs for metadata with attached files (eg. onlineResources with ‘File for download’ in
iso19139)
• setting date stamp/revision date
• setting codelist URLs to point to online ISO codelist catalogs
• adding default spatial reference system attributes to spatial extents
A specific task required for the MCP update-fixed-info.xsl was to automatically create an
online resource with a URL pointing to the metadata.show service with parameter set to the metadata
uuid. This required some changes to the update-fixed-info.xsl supplied with iso19139. In particular:
• the parent elements may not be present in the metadata record
• processing of the online resource elements for the metadata point of truth URL should not interfere
with other processing of online resource elements
Rather than describe the individual steps required to implement this and the decisions required in the
XSLT language, take a look at the update-fixed-info.xsl already present for the MCP schema
in the iso19139.mcp directory and refer to the dot points above.
7.3. Example - ISO19115/19139 Marine Community Profile (MCP)
55
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
Creating the templates directory
This is a simple directory. Put XML metadata files to be used as templates in this directory. Make sure
they have a .xml suffix. Templates in this directory can be added to the catalog using the Administration
menu.
Editor behaviour: Adding schema-suggestions.xml and schema-substitutes.xml
• schema-suggestions.xml - The default behaviour of the GeoNetwork advanced editor when building the editor forms is to show elements that are not in the metadata record as unexpanded elements. To add these elements to the record, the user will have to click on the ‘+’ icon next to
the element name. This can be tedious especially as some metadata standards have elements
nested in others (ie. complex elements). The schema-suggestions.xml file allows you to specify
elements that should be automatically expanded by the editor. An example of this is the online
resource information in the ISO19115/19139 standard. If the following XML was added to the
schema-suggestions.xml file:
<field name="gmd:CI_OnlineResource">
<suggest name="gmd:protocol"/>
<suggest name="gmd:name"/>
<suggest name="gmd:description"/>
</field>
The effect of this would be that when an online resource element was expanded, then input fields for the
protocol (a drop down/select list), name and description would automatically appear in the editor.
Once again, a good place to start when building a schema-suggestions.xml file for the MCP is
the schema-suggestions.xml file for the iso19139 schema.
• schema-substitutes.xml - Recall from the earlier Creating the schema directory and schema.xsd
file section, that the method we used to extend the base ISO19115/19139 schemas is to extend
the base type, define a new element with the extended base type and allow the new element to
substitute for the base element. So for example, in the MCP, we want to add a new resource
constraint element that holds Creative Commons and other commons type licensing information.
This requires that the MD_Constraints type be extended and a new mcp:MD_Commons element
be defined which can substitute for gmd:MD_Constraints. This is shown in the following snippet
of XSD:
<xs:complexType name="MD_CommonsConstraints_Type">
<xs:annotation>
<xs:documentation>
Add MD_Commons as an extension of gmd:MD_Constraints_Type
</xs:documentation>
</xs:annotation>
<xs:complexContent>
<xs:extension base="gmd:MD_Constraints_Type">
<xs:sequence minOccurs="0">
<xs:element name="jurisdictionLink" type="gmd:URL_PropertyType" minOccurs="1"/>
<xs:element name="licenseLink" type="gmd:URL_PropertyType" minOccurs="1"/>
<xs:element name="imageLink" type="gmd:URL_PropertyType" minOccurs="1"/>
<xs:element name="licenseName" type="gco:CharacterString_PropertyType" minOccurs
<xs:element name="attributionConstraints" type="gco:CharacterString_PropertyType
<xs:element name="derivativeConstraints" type="gco:CharacterString_PropertyType"
<xs:element name="commercialUseConstraints" type="gco:CharacterString_PropertyTy
<xs:element name="collectiveWorksConstraints" type="gco:CharacterString_Property
56
Chapter 7. Schema Plugins
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
<xs:element name="otherConstraints" type="gco:CharacterString_PropertyType" minO
</xs:sequence>
<xs:attribute ref="mcp:commonsType" use="required"/>
<xs:attribute ref="gco:isoType" use="required" fixed="gmd:MD_Constraints"/>
</xs:extension>
</xs:complexContent>
</xs:complexType>
<xs:element name="MD_Commons" substitutionGroup="gmd:MD_Constraints" type="mcp:MD_Common
For MCP records, the GeoNetwork editor will show a choice of elements from the substitution group
for gmd:MD_Constraints when adding ‘Resource Constraints’ to the metadata document. This will now
include mcp:MD_Commons.
Note that by similar process, two other elements, now deprecated in favour of MD_Commons, were
also added as substitutes for MD_Constraints. If it was necessary to constrain the choices shown in this
menu, say to remove the deprecated elements and limit the choices to just legal, security and commons,
then this can be done by the following piece of XML in the schema-substitutes.xml file:
<field name="gmd:MD_Constraints">
<substitute name="gmd:MD_LegalConstraints"/>
<substitute name="gmd:MD_SecurityConstraints"/>
<substitute name="mcp:MD_Commons"/>
</field>
The result of this change is shown below.
Once again, a good place to start when building a schema-substitutes.xml file for the MCP is the schemasubstitutes.xml file for the iso19139 schema.

7.3.11 Adding components to support conversion of metadata records to other
schemas
Creating the convert directory
If the new GeoNetwork plugin schema is to support on the fly translation of metadata records to other
schemas, then the convert directory should be created and populated with appropriate XSLTs.
Supporting OAIPMH conversions
The OAIPMH server in GeoNetwork can deliver metadata records from any of the schemas
known to GeoNetwork.
It can also be configured to deliver schemas not known to
GeoNetwork if an XSLT exists to convert a metadata record to that schema.
The file
INSTALL_DIR/web/geonetwork/WEB-INF/config-oai-prefixes.xml describes the
schemas (known as prefixes in OAI speak) that can be produced by an XSLT. A simple example of
the content of this file is shown below:
<schemas>
<schema prefix="oai_dc" nsUrl="http://www.openarchives.org/OAI/2.0/"
schemaLocation="http://www.openarchives.org/OAI/2.0/oai_dc.xsd"/>
</schemas>
In the case of the prefix oai_dc shown above, if a schema converter with prefix oai_dc exists in the
schema-conversions.xml file of a GeoNetwork schema, then records that belong to this schema
will be transformed and included in OAIPMH requests for the oai_dc prefix. See Creating the schemaconversions.xml file for more info.
To add oai_dc support for the MCP, the easiest method is to copy oai_dc.xsl from the convert directory
of the iso19139 schema, modify it to cope with the different namespaces and additional elements of the
MCP and add it to the schema-conversions.xml file for the MCP.

CHAPTER 8
Metadata Exchange Format
8.1 Introduction
The metadata exchange format (MEF in short) is a specially designed file format for the purpose of
metadata exchange between different platforms. A metadata exported as a MEF can be imported by
any platform which is able to understand MEF. This format has been developed with GeoNetwork in
mind so the information it contains is mainly related to GeoNetwork. Nevertheless, it can be used as an
interoperability format between different platforms.
This format has been designed with the following needs in mind:
1. Export a metadata record for backup purposes
2. Import a metadata record from a previous backup
3. Import a metadata record from a different GeoNetwork version to allow a smooth migration from
one version to another.
4. Capture metadata plus thumbnails and any data uploaded with the metadata record.
In the paragraphs below, some terms should be intended as follows:
1. the term actor is used to indicate any system (application, service etc...) that operates on metadata.
2. the term reader will be used to indicate any actor that can import metadata from a MEF file.
3. the term writer will be used to indicate any actor that can generate a MEF file.
8.2 MEF v1 file format
A MEF file is simply a ZIP file which contains the following files:
Root
|
+--+--+--|
+---
metadata.xml
info.xml
public
+---- all public documents and thumbnails
private
+---- all private documents and thumbnails
59
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
1. metadata.xml: this file contains the metadata itself, in XML format. The text encoding of the
metadata (eg. UTF-8) is specified in the XML declaration.
2. info.xml: this is a special XML file which contains information related to the metadata (metadata about the metadata). Examples of the information in the info.xml file are: creation date,
modification date, privileges This information is needed by GeoNetwork.
3. public: this is a directory used to store the metadata thumbnails and other public files. There are
no restrictions on the image format but it is strongly recommended to use the portable network
graphics (PNG), JPEG or GIF format.
4. private: this is a directory used to store all data (maps, shape files etc...) uploaded with the metadata in the GeoNetwork editor. Files in this directory are private in the sense that authorisation
is required to access them. There are no restrictions on the file types that can be stored into this
directory.
Any other file or directory present in the MEF file should be ignored by readers that don’t recognise
them. This allows actors to add custom extensions to the MEF file.
A MEF file can have empty public and private folders depending upon the export format, which can be:
• simple: both public and private are omitted.
• partial: only public files are provided.
• full: both public and private files are provided.
It is recommended to use the .mef extension when naming MEF files.
8.3 MEF v2 file format
MEF version 2 support the following:
• multi-metadata support: more than one metadata record and data can be stored in a single MEF
file.
• multi-schema support: be able to store in a single MEF n formats (eg. for an ISO profile, also
store a version of that record in the base ISO19115/ISO19139 schema).
Current export services that create MEF files from a metadata record with related records (eg. paent,
feature catalog etc), can include these related metadata records in the MEF. See mef.export.
MEF v2 format structure is the following:
Root
|
+ 0..n metadata
|
+--- metadata
|
+--- metadata.xml
|
+--- (optional) metadata.iso19139.xml
+--- info.xml
+--- applschema
|
+--- (optional) metadata.xml (ISO19110 Feature Catalog)
+--- public
|
+---- all public documents and thumbnails
+--- private
+---- all private documents and thumbnails
60
Chapter 8. Metadata Exchange Format
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
Note: metadata.iso19139.xml is generated by GeoNetwork actors on export if the metadata record in
metadata.xml is an ISO19115/19139 profile. On import, this record may be selected for loading if the
ISO19115/19139 profile is not present.
8.4 The info.xml file
This file contains general information about a metadata. It must have an info root element with a mandatory version attribute. This attribute must be in the X.Y form, where X represents the major version
and Y the minor one. The purpose of this attribute is to allow future changes of this format maintaining
compatibility with older readers. The policy behind the version is this:
1. A change to Y means a minor change. All existing elements in the previous version must be left
unchanged: only new elements or attributes may be added. A reader capable of reading version
X.Y is also capable of reading version X.Y’ with Y’>Y.
2. A change to X means a major change. Usually, a reader of version X.Y is not able to read version
X’.Y with X’>X.
The root element must have the following children:
1. general: a container for general information. It must have the following children:
• uuid: this is the universally unique identifier assigned to the metadata and must be a valid
UUID. This element is optional and, when omitted, the reader should generate one. A metadata without a UUID can be imported several times into the same system without breaking
uniqueness constraints. When missing, the reader should also generate the siteId value.
• createDate: This date indicates when the metadata was created.
• changeDate: This date keeps track of the most recent change to the metadata.
• siteId: This is an UUID that identifies the actor that created the metadata and must be a valid
UUID. When the UUID element is missing, this element should be missing too. If present,
it will be ignored.
• siteName: This is a human readable name for the actor that created the metadata. It must be
present only if the siteId is present.
• schema: The name of the schema for the metadata record in metadata.xml. When the MEF
is imported by a GeoNetwork actor, this name should be the name of a metadata schema
handled by the actor (eg. iso19139). If the GeoNetwork actor does not have such a schema,
it may try and select another metadata with a schema that is present (eg. the metadata in
metadata-iso19139.xml could be loaded because the iso19139 schema is present).
• format: Indicates the MEF export format. The element’s value must belong to the following
set: { simple, partial, full }.
• localId: This is an optional element. If present, indicates the id used locally by the sourceId
actor to store the metadata. Its purpose is just to allow the reuse of the same local id when
reimporting a metadata.
• isTemplate: A boolean field that indicates if this metadata is a template used to create new
ones. There is no real distinction between a real metadata and a template but some actors
use it to allow fast metadata creation. The value must be: { true, false }.
8.4. The info.xml file
61
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
• rating: This is an optional element. If present, indicates the users’ rating of the metadata
ranging from 1 (a bad rating) to 5 (an excellent rating). The special value 0 means that the
metadata has not been rated yet. Can be used to sort search results.
• popularity: Another optional value. If present, indicates the popularity of the metadata. The
value must be positive and high values mean high popularity. The criteria used to set the
popularity is left to the writer. Its main purpose is to provide a metadata ordering during a
search.
2. categories: a container for categories associated to this metadata. A category is just a name, like
’audio-video’ that classifies the metadata to allow an easy search. Each category is specified by a
category element which must have a name attribute. This attribute is used to store the category’s
name. If there are no categories, the categories element will be empty.
3. privileges: a container for privileges associated to this metadata. Privileges are operations that a
group (which represents a set of users) can do on a metadata and are specified by a set of group
elements. Each one of these, has a mandatory name attribute to store the group’s name and a set of
operation elements used to store the operations allowed on the metadata. Each operation element
must have a name attribute which value must belong to the following set: { view, download, notify,
dynamic, featured }. If there are no groups or the actor does not have the concept of group, the
privileges element will be empty. A group element without any operation element must be ignored
by readers.
4. public: All metadata thumbnails (and any other public file) must be listed here. This container
contains a file element for each file. Mandatory attributes of this element are name, which represents the file’s name and changeDate, which contains the date of the latest change to the file. The
public element is optional but, if present, must contain all the files present in the metadata’s public
directory and any reader that imports these files must set the latest change date on these using the
provided ones. The purpose of this element is to provide more information in the case the MEF
format is used for metadata harvesting.
5. private: This element has the same purpose and structure of the public element but is related to
maps and all other private files.
Any other element or attribute should be ignored by readers that don’t understand them. This allows
actors to add custom attributes or subtrees to the XML.
8.4.1 Date format
Unless differently specified, all dates in this file must be in the ISO/8601 format. The pattern must be
YYYY-MM-DDTHH:mm:SS and the timezone should be the local one. Example of info file:
<info version="1.0">
<general>
<uuid>0619abc0-708b-eeda-8202-000d98959033</uuid>
<createDate>2006-12-11T10:33:21</createDate>

XML Services
9.1 Calling specifications
9.1.1 Calling XML services
GeoNetwork provides access to its functions through the use of XML services. These services are much
like HTML addresses but return XML instead of HTML. The advantage of using XML, is that XML
services can be used in machine-to-machine interfaces. As an example, consider the xml.info service
- Site Information (xml.info): you might have an application which can use this service to get information
about GeoNetwork users and metadata schemas in XML. The user information returned by this service
could then be used by your application to decide how to authenticate with GeoNetwork so that metadata
records from a particular metadata schema could be retrieved from other GeoNetwork XML services
and processed by your application.
As a general rule, XML services provided by GeoNetwork usually have a xml. prefix in their address.
To keep things simple and uniform, GeoNetwork XML services accept XML documents (or convert
parameters to XML documents) and return information, status and errors as XML documents (except
for a few services that relate to file download and must return binary data).
Request
Each service accepts a set of parameters, which must be embedded in the request. A service can be
called using different HTTP methods, depending on the structure of its request:
• GET The parameters are sent as part of the URL address. On the server side, these parameters are
grouped into a flat XML document with one root and several simple children. A service can be
called this way only if the parameters it accepts are not structured. An example of such a request
and the parameters encoded in XML is:
Url Request:
http://localhost:8080/geonetwork/srv/eng/main.search?hitsPerPage=10&any=
Encoding:
<request>
<hitsPerPage>10</hitsPerPage>
<any />
</request>

1. ENCODED The request has one of the following content types: application/x-www-formurlencoded or multipart/form-data. The first case is very common when sending web forms
while the second one is used to send binary data (usually files) to the server. In these cases,
the parameters are not structured so the rules of the GET method applies. Even if the second
case could be used to send XML documents, this possibility is not considered on the server
side.
2. XML The content type is application/xml. This is the common case when the client is not
a browser but a specialised client. The request is a pure XML document in string form,
encoded using the encoding specified into the prologue of the XML document. Using this
form, any type of request can be made (structured or not) so any service can be called.
3. SOAP The content type is application/soap+xml. SOAP is a simple protocol used to access
objects and services using XML. Clients that use this protocol can embed XML requests into
a SOAP structure. On the server side, GeoNetwork will remove the SOAP structure and feed
the content to the service. Its response will be embedded again into a SOAP structure and
sent back to the caller. It makes sense to use this protocol if it is the only protocol understood
by the client.
Response
The response of an XML service always has a content type of application/xml (the only exception are
those services which return binary data). The document encoding is the one specified in the document
prologue which is UTF-8 (all GeoNetwork services return documents in the UTF-8 encoding).
On a GET request, the client can force a SOAP response by adding the application/soap+xml content
type to the Accept header parameter.
9.1.2 Exception handling
A response document having an error root element means that the XML service raised an exception.
This can happen under several conditions: bad parameters, internal errors et cetera. In this cases the
returned XML document has the following structure:
• error: This is the root element of the document. It has a mandatory id attribute that represents the
identifier of the error. See below for a list of identifier values.
– message: A message related to the error. It can be a short description about the error type or
it can contain some other information that details the id code.
– class: The Java class name of the Exception that occurred.
– stack: Execution path from method where Exception occurred to earliest method called by
GeoNetwork. Each level in the execution path has an at child.
* at: Information about the code being called when the exception occurred. It has the
following mandatory attributes:
· class Java class name of the method that was called.
· file Source file where the class is defined.
· method Method name in class.
66
Chapter 9. XML Services
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
· line Source code line number in file.
– object: An optional container for parameters or other values that caused the exception. In
case a parameter is an XML object, this container will contain that object in XML form.
– request: A container for request information.
* language: Language used when the service was called.
* service: Name of the service that was called.

Below is an example of exception generated by the mef.export service. The service complains about a
missing parameter, as you can see from the content of the id attribute. The object element contains the
xml request with an unknown test parameter while the mandatory UUID parameter (as specified by the
message element) is missing.

9.2 Login and Logout services
9.2.1 Login services
GeoNetwork standard login (xml.user.login)
The xml.user.login service is used to authenticate the user in GeoNetwork. Authenticated users can use
XML services that require authentication such as those used to maintain group or user information.
Request
Parameters:
• username (mandatory): Login for the user to authenticate
• password (mandatory): Password for the user to authenticate
Login request example:
Url:
http://localhost:8080/geonetwork/srv/en/xml.user.login
Mime-type:
application/xml
Post request:
<?xml version="1.0" encoding="UTF-8"?>
<request>
<username>admin</username>
<password>admin</password>
</request>
68
Chapter 9. XML Services
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
Response
When user authentication is successful HTTP status code 200 is returned along with an XML response
as follows:
<ok/>
If the response headers are examined, they will look something like the following::
Expires: Thu, 01 Jan 1970 00:00:00 GMT
Set-Cookie: JSESSIONID=1xh3kpownhmjh;Path=/geonetwork
Content-Type: application/xml; charset=UTF-8
Pragma: no-cache
Cache-Control: no-cache
Transfer-Encoding: chunked
The authentication process sets the JSESSIONID cookie with the authentication token. This token
should be sent as part of the request to all services that need authentication.
If the execution of the login request is not successful then an HTTP 500 status code error is returned
along with an XML document that describes the exception/what went wrong. An example of such a
response is::
<error id="user-login">
<message>User login failed</message>
<class>UserLoginEx</class>

9.14 Metadata Processing services
These services allow processing of one or more metadata records using an XSLT.
9.14.1 Rules for constructing a process XSLT for use with these services
Typically an XSLT used with this service will accept some parameters then filter the elements of the
metadata record being processed, changing some elements and copying the rest. So the rules for constructing such an XSLT are:
• Accept parameters using xsl:param - values for these will be specified as part of the request.
eg. <xsl:param name="url"/>
• Add templates that match and process the required metadata elements. For example:
132
Chapter 9. XML Services
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
<xsl:template match="gmd:identificationInfo/*">
<!-- Do some work processing and/or copying contents of this element -->
</xsl:template>
• Include a template that matches all content, refers any specific matches to templates provided in
the previous step or just copies the metadata elements (nodes) and attributes without changing
them.
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
• Put the process XSLT into the process directory of the relevant metadata
schema plugin.
eg.
if your process XSLT applies to iso19139 metadata
records then it should be in the process directory of the iso19139 schema
(GEONETWORK_DATA_DIR/config/schema_plugins/iso19139/process).
9.14.2 Process a metadata record with an XSLT (xml.metadata.processing)
This service applies an XSLT to a metadata record specified by id or uuid.
Request
Parameters:
• id or uuid: Identifier of metadata to process.
• save: Set to ‘1’ to save the processed metadata (default), ‘0’ will not save the processed metadata
and will return the processed metadata for inspection.
• process: Name of an XSLT in the process directory of a metadata schema in GeoNetwork. For
example, anonymizer.xsl exists in the process directory of metadata schema iso19139 - to
use this XSLT you would specific anonymizer as the process parameter value.
• Parameters of the process XSLT in order. Each parameter of the process XSLT needs to be specified with a value if no default exists in the process XSLT or with no value if the default is suitable.
You will need to examine the process XSLT to determine which parameters to specify and what
the default values are if any.
Example request for the anonymizer process XSLT:
POST:
Url:
http://localhost:8080/geonetwork/srv/eng/xml.metadata.processing
Mime-type:

<email>[email protected]<email/>
</request>
GET:
Url:
http://localhost:8080/geonetwork/srv/eng/xml.metadata.processing?&id=6&save=0&process=an
Response
If the processing specified in the request succeeded and the parameter save was set to ‘1’ or left out,
then the XML response contains the id of the metadata record that was processed. For example:
<response>
<id>1</id>
</response>
If the processing specified in the request succeeded and the parameter save was set to ‘0’, then the
XML response contains the id of the metadata record and the processed metadata record. For example,
if processing an iso19139 metadata record then the response would contain the processed iso19139
metadata record as follows:
<response>
<id>2</id>
<record>
<gmd:MD_Metadata ...>
.....
</gmd:MD_Metadata>
</record>
</response>
If the processing specified in the request failed, an XML error response is returned with the reason.
For example, here is the response when processing was requested on a metadata record belonging to a
metadata schema that does not have the specified processing XSLT:
<error id="bad-parameter">
<message>Processing failed</message>
.....
<object>Not found:0, Not owner:0, No process found:1.</object>

9.14.3 Batch
process
metadata
(xml.metadata.batch.processing)
records
with
an
XSLT
The xml.metadata.batch.processing service applies an XSLT to each metadata record in a selected set
of metadata records.
Note: This service requires a previous call to the xml.metadata.select service (see Select metadata records (xml.metadata.select)) to select metadata records.
Note: This service is only available to users with UserAdmin or Administrator profile.
Note: Only those metadata records for which the user running the service has editing rights on will be
processed. If metadata versioning is on then any changes to the metadata records will be recorded in the
version history.
Requires authentication: Yes
Request
Parameters:
• save: Set to ‘1’ to save the processed metadata (default), ‘0’ will not save the processed metadata.
• process: Name of an XSLT in the process directory of a metadata schema in GeoNetwork. For
example, the anonymizer XSLT exists in the process directory of metadata schema iso19139 - to
use this XSLT you would specific anonymizer as the process parameter value.
• Parameters of the process XSLT in order. Each parameter of the process XSLT needs to be specified with a value if no default exists in the process XSLT or with no value if the default is suitable.
You will need to examine the process XSLT to determine which parameters to specify and what
the default values are if any.
Example request for the anonymizer process XSLT:
POST:
Url:
http://localhost:8080/geonetwork/srv/eng/xml.metadata.batch.processing
Mime-type:

Response
If the request executed successfully then HTTP 200 status code is returned and an XML document with
a summary of how the metadata records in the selected set have been processed. An example of such a
response is shown below:
<response>
<done>5</done>
<notProcessFound>2</notProcessFound>
<notOwner>0</notOwner>
<notFound>0</notFound>
</response>
The response fields are:
• done - number of metadata records successfully updated
• notProcessFound - number of metadata records skipped because the process XSLT was not
present in their metadata schema
• notOwner - number of metadata records skipped because the user running this service did not
have ownership rights
• notFound - number of metadata records skipped because they were not found (may have been
deleted)
If the request fails an HTTP 500 status code error is returned and the response is an XML document
with the exception. An example of such a response is shown below:
<error id="service-not-allowed">
<message>Service not allowed</message>
.....
<object>xml.metadata.batch.processing</object>
.....
</error>
See Exception handling for more details.
Errors
• Service not allowed (error id: service-not-allowed), when the user is not authenticated or their
profile has no rights to execute the service. Returns 500 HTTP code
9.14.4 Batch update child records (xml.metadata.batch.update.children)
The xml.metadata.batch.update.children service copies metadata elements from the parent metadata
record to all child metadata elements.
• This service works only for iso19139 (or profile) child metadata records ie. metadata records
whose gmd:parentIdentifier is set to the uuid of a metadata record in the catalog.
136
Chapter 9. XML Services
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
• Any child metadata records that do not have the same metadata schema as the parent metadata
record will be skipped.
• The service actually executes an XSLT in the metadata schema directory of the parent metadata
record. The XSLT is called update-child-from-parent-info.xsl. It is run on each
child metadata record and is passed parameters from the request as required. This design has been
chosen to make customization of the service reasonably straight forward.
Note: If user of this service does not have edit privileges over a child metadata record then that record
will be skipped.
Requires authentication: Yes
Request
Parameters:
• id: GeoNetwork internal integer id of parent metadata record.
• parentUuid: Uuid of parent metadata record.
• schema: Metadata schema name in GeoNetwork.
• childrenIds: GeoNetwork internal integer ids of child metadata records (comma separated)
• updateMode: ‘replace’ means replace content in the children with content from the parent. ‘add’
means add content from the parent to the child metadata records.
• Parameters for update-child-from-parent-info.xsl. Examine the relevant XSLT to
determine which parameters to specify.

9.15 Metadata Relation services
This section describes the services used to show, get, insert and delete relations between metadata
records in GeoNetwork. If the metadata schema has elements that support relationships between metadata records (eg. ISO19115/19139), then the relationships are stored in the Lucene index with the
metadata record. If a relationship concept does not exist in the metadata schema, then the relationship is
stored in the Relations table as follows:
Field
id
relatedId
Datatype
foreign key to Metadata(id)
foreign key to Metadata(id)
Description
Source metadata
Metadata related to the source
9.15.1 Get all related records for a metadata record (xml.relation)
This service retrieves all the related records for a source metadata record specified by id in the parameters. The relationships can come from the Lucene index and/or the Relations table in the database.
138
Chapter 9. XML Services
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
Request
• id (integer): This is the local GeoNetwork identifier of the metadata whose relations are requested.
Here is an example of POST/XML request:
<request>
<id>10</id>
</request>
Response
If the request executed successfully then HTTP status code 200 is returned along with an XML document
containing a relations root element and a relation child for each type of relation found. Example:
<relations>
<relation type="parent">
<id>3</id>
<uuid>da165110-88fd-11da-a88f-000d939bc5d8</uuid>
<title>....</title>
<abstract>....</abstract>
</relation>
</relations>
Each relation element has a type attribute indicating the type of relation with the metadata record id
specified in the parameters. The XML elements returned vary for each type attribute as follows:
• relation type=parent: elements describe the parent metadata record of the specified metadata
record:
• id: GeoNetwork internal id (integer)
• uuid: Metadata uuid
• title: Metadata title
• abstract: A brief explanation of the metadata
• relation type=children: metadata element describes the child metadata record of the specified
metadata record
• metadata: container for child metadata record
– title: Metadata title
– abstract: A brief explanation of the metadata
* Other elements returned by a brief presentation of the child metadata record
• relation type=services: multiple metadata elements describing the service metadata records that
operate on the specified metadata record:

exist.
xml.relation.insert
This service creates a relationship between a parent metadata record and a child metadata record. The
relationship is held in the Relations table ie. relationships inserted using this service are those that cannot
be held in a metadata record.
Request
• parentId (integer) or parentUuid: This is the identifier of the metadata which we are inserting a
relationship for.
• childId (integer) or parentUuid: This is the identifier of the metadata which will be related to
metadata record specified by parentId or parentUuid.

9.16 Metadata Validation services
These services are for validating metadata against the XML schema documents (XSDs) and schematrons
specified as part of a GeoNetwork Metadata Schema. See Schema Plugins for more details.
9.16.1 Validate a metadata record (xml.metadata.validation)
This service can be used to validate a metadata record supplied as an XML parameter. The metadata
record is first passed through the GeoNetwork schema detection rules (see Schema Plugins). After
successful schema detection the metadata record is validated against the XML schema documents and
schematrons (if any) specified in that schema.
Authentication required: No
Request
Parameters:
• data: Metadata record.
Example with an ISO19115/19139 metadata record:
Url:
http://localhost:8080/geonetwork/srv/eng/xml.metadata.validation
Mime-type:
application/xml
Post request:
<?xml version="1.0" encoding="UTF-8"?>
<request>
<data><![CDATA[
<gmd:MD_Metadata ....>
.....
</gmd:MD_Metadata>
]]></data>
</request>
Response
If the validation is successful an HTTP 200 response code is returned along with an XML document giving details of the GeoNetwork metadata schema that the record matched and was successfully validated
against.
Example:
<?xml version="1.0" encoding="UTF-8"?>
<response>
<valid>y</valid>
<schema>iso19139</schema>
</response>
If the validation was not successful then an HTTP 500 error response code is returned along with an
XML document describing the validation problems. An example is:
144
Chapter 9. XML Services

9.17 System configuration
9.17.1 Introduction
GeoNetwork configuration parameters can be changed to suit the needs of your site. There are two
groups of parameters:
9.17. System configuration
147
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
• parameters that can be changed through the web interface.
• parameters not accessible from the web interface and that must be changed when the system is not
running
The first group of parameters can be queried or changed through the two services described in this

153
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
9.17.3 xml.config.set
This service is used to update the system configuration. It is restricted to users with the Administrator
profile.
Request
The request format is the same as the XML document produced by the xml.config.get service. To
use the xml.config.set service in the simplest way:
1. Call xml.config.get to obtain an XML document describing the current configuration.
2. Update the content of the elements you want to change.
3. POST the modified XML document describing the new configuration to xml.config.set.
So a typical POST request would look like::
Url: http://localhost:8080/geonetwork/srv/eng/xml.config.set
<request>
<config>
.....
</config>
</request>
Response
If the request executed successfully then HTTP status code 200 is returned along with an XML document
confirming success. The success response is::
<response>ok</response>
If an exception occurred then an XML document with the details of the exception is returned.
See Exception handling for more details.
9.18 Site Information and Request Forwarding Services
Services in this section provide information about the site (eg. name, users, groups, schemas etc) and
access to the site forwarding service which can be used by JavaScript clients.
9.18.1 Site Information (xml.info)
This service can be used to retrieve information about a GeoNetwork site. The information that can
be requested includes: site name and id, users, groups, metadata schemas as well as lists of privileges,
metadata status values, spatial regions, local metadata categories and so on.
154
Chapter 9. XML Services
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
Request
The XML request should contain at least one type parameter to indicate the kind of information to
retrieve. Multiple type parameters can be specified. The set of allowed values is:
• site: Returns general information about the site like its name, id, etc...
• users: Depending upon the profile of the user making the call, information about users of the site
will be returned. The rules are:
• Administrators can see all users
• User administrators can see all users they administer and all other user administrators in the same
group set. The group set is defined by all groups visible to the user administrator (except for the
All and Intranet groups).
• An authenticated user can only see their own information.
• A guest cannot see any user information at all.
• groups: Returns all user groups visible to the requesting user. Note: If the user is not authenticated, only the Intranet and All groups will be returned.
• sources: Returns all GeoNetwork sources (remote sites) that are known about at the site. This
will include:
• Node name and siteId
• All source UUIDs and site names that have been discovered through harvesting
• All source UUIDs and site names from MEF files imported by the site
• schemas: Returns all registered metadata schemas for the site
• categories: Returns the metadata categories for the site
• operations: Returns all possible operations on metadata
• regions: Returns all geographical regions usable for spatial queries
• status: Returns all possible status values for metadata records
Request example:
<request>
<type>site</type>
<type>groups</type>
</request>
Response
Each type parameter produces an XML subtree in an info container element. An example response to a
request for site, categories and groups information would look like the following:
<info>
<site>...</site>
<categories>...</categories>
<groups>...</groups>
</info>
The structure of each possible subtree is as follows:

<converter name="xml_iso19139Tooai_dc" nsUri="http://www.openarchives.org/OAI/2.0/"
</conversions>
</schema>
...
</schemas>
Looking at the example schema (iso19139) above,
there are two converters.
The first is invoked by calling the GeoNetwork service xml_iso19139 (eg.
http://somehost/geonetwork/srv/eng/xml_iso19139?uuid=<uuid
of metadata>).
It
produces
an
XML
format
with
namespace
URI
http://www.isotc211.org/gmd

9.19 File download services
This section provides a detailed explanation of GeoNetwork file download services. These are the services you would use if you want to download a file attached to a metadata record as ‘Data for Download’
(usually in onlineResources section of an ISO record) or perhaps as a gmx:FileName (where allowed).
The two services, used together, can be used to create a simple click through licensing scheme for file
resources attached to metadata records in GeoNetwork.
9.19.1 xml.file.disclaimer
Retrieves information from the metadata about constraints or restrictions on the resources attached to the
metadata record. The information is xml and an xhtml presentation of the constraints and restrictions.
Note: only users that have download rights over the record will be able to use this service. To obtain
these rights your application will need to use xml.user.login - see GeoNetwork standard login
(xml.user.login).
Request
Called with a metadata id or uuid, one or more file names (if more than one file is attached to the
metadata record as ‘data for download’) and access (which is almost always private). Example:
<request>
<uuid>d8c8ca11-ecc8-45dc-b424-171a9e212220</uuid>
<fname>roam-rsf-aus-bathy-topo-contours.sff</fname>
<fname>mse09_M8.nc</fname>
<access>private</access>
</request>
Response
The service returns a copy of the request parameters, a copy of the metadata record xml
and an HTML version of the license annex generated from the metadata record by the XSL
metadata-license-annex.xsl (in the INSTALL_DIR/web/geonetwork/xsl directory).
Example of an xml.file.disclaimer response for a GeoNetwork node (Note: the <metadata>
and <license> elements are not shown in full as they are too big):
<response>
<id>22</id>
<uuid>d8c8ca11-ecc8-45dc-b424-171a9e212220</uuid>

The idea behind this service is that you will receive an HTML presentation of the constraints/restrictions
on the resource that you can show to a user for an accept/decline response.
The HTML presentation is controlled by the server so together with the xml.file.download service, this is the way that GeoNetwork can be used to provide a simple click-through licensing system
for file resources attached to metadata records.
To signify acceptance of the license and download the resources you should use the
xml.file.download service.
If an exception occurred then the service returns HTTP status code 500 and an XML document describing what went wrong. An example of such a response is:
<error id="metadata-not-found">
<message>Metadata not found</message>
<class>MetadataNotFoundEx</class>
.......
</error>
See Exception handling for more details.
Errors
• IllegalArgumentException: Request must contain a UUID or an ID parameter.
• MetadataNotFoundException: Metadata not found.
• OperationNowAllowedException: you don’t have download permission over this record.
9.19.2 xml.file.download
After your application has received any license conditions that go with the file resources attached to the
metadata record from xml.file.disclaimer, you can use this service to download the resources.
Note: only users that have download rights over the record will be able to use this service. To obtain
these rights your application will need to use xml.user.login - see GeoNetwork standard login
(xml.user.login).
Note:
this service is protected against users and/or applications that do not go through the
xml.file.disclaimer service first.

Chapter 9. XML Services
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
Request
Called with a metadata id or uuid, one or more file names (if more than one file is attached to the
metadata record as ‘data for download’), access (which is almost always private) and details of the user
who has accepted the license and wants to download the files. Example:
<request>
<uuid>d8c8ca11-ecc8-45dc-b424-171a9e212220</uuid>
<fname>roam-rsf-aus-bathy-topo-contours.sff</fname>

<access>private</access>
<name>Aloyisus Wankania</name>
<org>Allens Butter Factory</org>
<email>[email protected]</email>
<comments>Gimme the data buddy</comments>
</request>
Response
The service returns HTTP status code 200 along with a zip archive containing:
• the file resources requested in the fname parameter(s)
• a copy of the metadata record (as a mef) - called metadata.zip
• a copy of the html license generated (as provided by the xml.file.disclaimer service) called license-annex.html
If an exception occurs or the xml.file.disclaimer service has not been executed by the same
user, then a zero-length file will be returned. Unlike other GeoNetwork services, no other indication of
an exception is given.
9.20 Harvesting services
This section describes the services used to create, update and manage GeoNetwork harvesters. These
services allow complete control over harvester behaviour. Authentication is required for all services
described in this section. In addition, these services can only be run by users with the Administrator
profile.
9.20.1 Get harvester definitions (xml.harvesting.get)
Retrieves information about one or all configured harvesters.
Request
Called without parameters, this service returns all harvesters. Example:
<request/>
Otherwise, an id parameter can be specified to request the definition of a specific harvester instance:
9.20. Harvesting services
165
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
<request>
<id>123</id>
</request>
Response
When called without parameters the service returns HTTP status code 200 along with an XML document
with all harvester instances. The XML document has a root element called nodes with a node child
for each harvester.
Example of an xml.harvesting.get response for a GeoNetwork harvester:
<nodes>

Each harvester has some common XML elements, plus additional elements that are specific to each
harvesting type.
The common XML elements are described at Harvesting nodes.
If an error occurred then HTTP status code 500 is returned along with an XML document which contains
details of what went wrong. An example of such an error response is:

See Exception handling for more details.
Errors
• ObjectNotFoundEx If a harvester definition with the specified id cannot be found.
9.20.2 Create harvester instance (xml.harvesting.add)
Create a new harvester. The harvester can be of any type supported by GeoNetwork (see Harvesting
nodes for a list). When a new harvester instance is created, its status is set to inactive. A call to the
xml.harvesting.start service is required to set the status to active and run the harvester at the
scheduled time.
Request
The service requires an XML tree with all information about the harvesting node to be added. The
common XML elements that must be in the tree are described at Harvesting nodes. Settings and example
requests for each type of harvester in GeoNetwork are as follows:
• Harvesting node geonetwork
• Harvesting node webdav
• Harvesting node csw
• Harvesting node z3950
• Harvesting node oaipmh
• Harvesting node thredds
• Harvesting node wfsfeatures
• Harvesting node filesystem

See Exception handling for more details.
9.20.4 Update a Harvester Instance (xml.harvesting.update)
This service can be used to change the parameters of a harvester instance.
Note: You cannot change the harvester type.
Request
The simplest way to use this service is to:
1. use the xml.harvesting.get service to obtain the XML definition of the harvester that you
want to update.
2. modify the parameters as required.
3. call this service with the modified XML definition of the harvester as the request.
The XML request is the same as that used in xml.harvesting.add.
Response
If the update succeeded then HTTP status code 200 is returned along with an XML document containing
the harvester definition as supplied in the request.
If an error occurred then HTTP status code 500 is returned along with an XML document which contains
details of what went wrong. An example of such an error response is:
174

See Exception handling for more details.
9.20.5 Control or Remove a Harvester Instance (xml.harvesting.remove,
xml.harvesting.start, xml.harvesting.stop, xml.harvesting.run)
These services are described in on section because they share a common request interface. Their purpose
is to remove, start, stop or run a harvester:
1. remove: Remove a harvester. Deletes the harvester instance.
2. start: When created, a harvester is in the inactive state. This operation makes it active which
means it will be run at the enxt scheduled time.
3. stop: Makes a harvester inactive - it will no longer be executed at the scheduled time. Note this
will not stop a harvester that is already performing a harvest.
4. run: Start the harvester now. Used to test the harvesting.
Request
A set of ids to operate on. Example:
<request>
<id>123</id>
<id>456</id>
<id>789</id>
</request>
Response
Similar to the request but every id has a status attribute indicating the success or failure of the operation.
For example, the response to the previous request could be:
<response>
<id status="ok">123</id>
<id status="not-found">456</id>
<id status="inactive">789</id>
</response>
The table below summarises, for each service, the possible status values.

If the request has no id parameters, an empty response is returned.
Most errors relating to a harvester specified in the request (eg. harvester id not found) are returned as
status attributes in the response. However, exceptions can still occur, in which case HTTP status code
500 is returned along with an XML document which contains details of what went wrong. An example
of such an error response is:
<error id="service-not-allowed">
<message>Service not allowed</message>
<class>ServiceNotAllowedEx</class>
.....
</error>
See Exception handling for more details.
9.20.6 Retrieve Harvesting History (xml.harvesting.history)
This service can be used to retrive the history of harvest sessions for a specified harvester instance or
all harvester instances. The harvester history information is stored in the GeoNetwork database in the
HarvestHistory table.
Request
Called without an id parameter, this service returns the harvest history of all harvesters. The response
can be sorted by harvest date or by harvester type. The sort order is specified in the parameter sort.
Example:
<request>
<sort>date</sort>
</request>
Otherwise, an id parameter can be specified to request the harvest history of a specific harvester instance.
In this case the sort order is by date of harvest:
<request>
<id>123</id>
</request>
Response
If the update succeeded then HTTP status code 200 is returned along with an XML document containing
the harvest history. The response for both types of requests is the same except that the response to
a request for the history of a specific harvester will only have history details for that harvester. An
example of the response is:
<response>
<response>
<record>
<id>1</id>
<harvestdate>2013-01-01T19:24:54</harvestdate>
<harvesteruuid>b6a11fc3-3f6f-494b-a8f3-35eaadced575</harvesteruuid>

Each record element in the embedded response element contains the details of a harvest session. The
elements are:
• id - harvest history record id in harvesthistory table
• harvestdate - date of harvest
• harvesteruuid - uuid of harvester that ran
• harvestername - name of harvester (Site/Name parameter) that ran
• harvestertype - type of harvester that ran
• deleted - has the harvester that ran been deleted? ‘y’ - yes, ‘n’ - no
• info - results of the harvest. May contain one of the following elements:
• result - details of the successful harvest (a harvester dependent list of results from the harvest)
• error - an exception from an unsuccessful harvest - see Exception handling for content details of
this element
• params - the parameters that the harvester had been configured with for the harvest
After the embedded response element, the currently configured harvesters are returned as node children
of a nodes element - see Create harvester instance (xml.harvesting.add) for references to each of the
harvester types that can be returned here.
If an error occurred then HTTP status code 500 is returned along with an XML document which contains
details of what went wrong. An example of such an error response is:

9.20.7 Delete Harvesting History Entries (xml.harvesting.history.delete)
This service can be used to delete harvester history entries from the harvesthistory table in the GeoNetwork database.
Request
One or more id parameters can be specified to request deletion of the harvest history entries in
the harvesthistory table. The id element values can be obtained from Retrieve Harvesting History
(xml.harvesting.history):
<request>
<id>1</id>
<id>2</id>
</request>
Response
If successful then HTTP status code 200 is returned along with an XML document with details of how
many harvest history records were successfully deleted. An example of this response is:
<response>2</response>
Note: If records with the id specified in the parameters are not present, they will be quietly ignored.
If an error occurred then HTTP status code 500 is returned along with an XML document which contains
details of what went wrong. An example of such an error response is:
<error id="service-not-allowed">
<message>Service not allowed</message>
<class>ServiceNotAllowedEx</class>

9.21 Schema Services
Metadata schemas can be plugged into GeoNetwork - see Schema Plugins. Any application that needs
to:
• find information (eg. names, versions, namespaces, converters) about metadata schemas that are
plugged into GeoNetwork should use the Site Information (xml.info) service
• find information about the schema elements and codelists should use the xml.schema.info
service described in this section of the manual

9.21.1 Metadata Schema Information (xml.info?type=schemas)
See Site Information (xml.info) for more details.
9.21.2 Schema Element and Codelist Information (xml.schema.info)
This service returns information about a set of schema elements or codelists. The returned information
consists of a localised label, a description, conditions that the element must satisfy etc.
Request
Requests to this service can only be made using the HTTP POST binding with application/XML content
type. Requests can ask for information on multiple elements and codelists from different schemas.
Description of the request fields is as follows:
• element: Must contain a schema and a name attribute. The schema attribute must be the name of a
schema currently registered in GeoNetwork (see Site Information (xml.info) for more details). The
name attribute must be the qualified name of the metadata schema element on which information
is required. Other optional attributes can be specified to help determine the appropriate context
for the metadata element. These optional attributes are:
– context: The qualified name of the metadata schema element that is the parent of the element
specified in the name attribute.
– fullContext: The qualified xpath of the element specified in the name attribute.
– isoType: For profiles of ISO19115/19139 only. The qualified name of the element in the
base ISO19115/19139 schema that the element specified in the name attribute is a substitute
for. eg. in the Marine Community Profile of ISO19115/19139, mcp:MD_Metadata is a
substitute for gmd:MD_Metadata in the base ISO19115/19139 metadata schema.
• codelist: Accepts a schema and name attribute as for element but information on any codelist
associated with the qualified name of the metadata schema element in the name attribute will be
returned instead.
<request>
<element schema="iso19139" name="gmd:constraintLanguage" />

9.22 MEF services
This section describes the services related to the Metadata Exchange Format. These services allow
import/export metadata using the MEF (Metadata Exchange Format) format.
Note: before using these services please review the section on the MEF format at Metadata Exchange
Format
9.22.1 mef.export
This service exports GeoNetwork metadata using the MEF file format. The metadata record can be
specified using a uuid or the currently selected set of metadata records can be used - see Select metadata
records (xml.metadata.select) for more details on how to select a set of metadata records.
This service is public but metadata access rules apply. For a partial export, the view privilege is enough
but for a full export the download privilege is also required. Without a login step, only partial exports
on public metadata are allowed.
This service uses the system temporary directory to build the MEF file. By default the tmp
directory is INSTALL_DIR/web/geonetwork/data. You will need to ensure that sufficient disk space is available on that filesystem for full exports (ie. those that include data
files uploaded with the metadata record) to be successful. Alternatively, you can specify a
different directory by configuring the uploadDir parameter in the general section of the
INSTALL_DIR/web/geonetwork/WEB-INF/config.xml file.
Request
This service accepts requests in GET/POST and XML form. The input parameters are all optional and
are as follows:
184
Chapter 9. XML Services
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
• uuid the universal unique identifier of the metadata to be exported. If this parameter is optional
then the selected set of metadata will be exported. To select a set of metadata see Select metadata
records (xml.metadata.select).
• format which MEF format to use. Can be one of: simple, partial, full. Default is full - which
means thumbnails and data files uploaded with the metadata record are included in the MEF.
• skipUuid (true|false) If set to true, the metadata record UUIDs will not be exported into the MEF
info.xml file. Without a UUID (which is a unique key inside the database) the metadata records
in a MEF can be repeatedly imported as they will receive a new UUID on import. The default
value is false.
• version (true|false) If set to true, MEF Version 2.0 is used, otherwise MEF Version 1.0 is used.
This parameter needs to be present if related records are being included in the MEF - see the
relation parameter below.
• resolveXlink (true|false) If set to true, then any XLinks in the metadata records are resolved before the records are exported. If false, the metadata records are exported with unresolved XLinks.
Default is true.
• removeXlinkAttributes (true|false) If set to true, then any XLink attributes in the metadata
records are removed before the records are exported. Default is true.
• relation (true|false) If set to true and version is also set to true, then related records (eg.parent,
feature catalog) are exported into the MEF with the metadata record. Default is true.
Example POST request:
<request>
<uuid>f80bca2e-ff75-4107-8999-4c1864cb1b1b</uuid>
<format>full</format>
<skipUuid>true</skipUuid>
<version>true</version>
<relation>true</relation>
</request>
URL:
http://localhost:8080/geonetwork/srv/eng/mef.export
Response
If successful the service returns HTTP status code 200 and the response is a MEF file with name as
follows:
• prefix is export• MEF format: simple, partial, full
• current time in milliseconds since 1970
• zip extension
eg. export-full-1357949862822.zip
If an exception occurred then service returns HTTP status code 500 and an XML document describing
what went wrong. An example of such a response is:
9.22. MEF services
185
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
<error id="metadata-not-found">
<message>Metadata not found</message>
<class>MetadataNotFoundEx</class>
.......
</error>
See Exception handling for more details.
9.22.2 mef.import
This service is used to import a metadata record in the MEF format.
Only users with the Administrator profile can run this service.
Request
The service accepts a multipart/form-data POST request with a single mefFile parameter that must
contain the MEF information.
Response
If the import is successful, the service returns HTTP status code 200 along with an XML document
containing the GeoNetwork integer id of the created metadata. Example:
<ok>123</ok>
If an exception occurred then service returns HTTP status code 500 and an XML document describing
what went wrong. An example of such a response is:
<error id="metadata-not-found">
<message>Metadata not found</message>
<class>MetadataNotFoundEx</class>
.......
</error>
See Exception handling for more details.
Notes
• Version 1.0 of the MEF format does not capture the metadata owner (the creator) and the group
owner. During import, the user that is performing this operation will become the metadata owner
and the group owner will be set to null.
9.23 CSW service
GeoNetwork opensource catalog publishes metadata using the OGC CSW (Catalog Services for the
Web) protocol supporting HTTP binding to invoke the operations.
The protocol operations are described in the document OpenGIS® Catalogue Services Specification:
http://portal.opengeospatial.org/files/?artifact_id=20555
186
Chapter 9. XML Services
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
GeoNetwork is compliant with the 2.0.2 version of the specification, supporting the following CSW
operations:
• GetCapabilities
• DescribeRecord
• GetRecordById
• GetRecords
• Harvest
• Transaction
This chapter briefly describes the different operations supported in GeoNetwork and gives some usage
examples. To get a complete reference of the operations and parameters of each CSW operation refer to
the document OpenGIS® Catalogue Services Specification.
The invocation of the operations from a Java client is analogous as described in the chapter for XML
services.
9.23.1 CSW operations
The CSW operations are divided in 2 types: Discovery and Publication. The Discovery operations are
used to query the server about its capacities and to search and retrieve metadata from it. The Publication
opertions (Harvest and Transaction) are used to insert metadata into the catalog.
The CSW operations can be accesed using POST, GET methods and SOAP encoding.
The GeoNetwork opensource catalog CSW Discovery service operations are accessible through the url:
http://localhost:8080/geonetwork/srv/eng/csw
GetCapabilities
GetCapabilities operation allows CSW clients to retrieve service metadata from a server. The response
to a GetCapabilities request is an XML document containing service metadata about the server.

CHAPTER 10
Settings hierarchy
10.1 Introduction
GeoNetwork stores configuration settings in the Settings table. The settings are organized into a ‘tree’
structure where the leaf nodes of the tree are key/value pairs.
A key is limited to 64 characters whilst a value is effectively unlimited in most databases supported by
GeoNetwork.
The root of the tree contains two nodes:
• system: contains nodes that describe system configuration settings
• harvesting: contains nodes that describe the settings used by harvesters
In the following sections:
• the indentation is used to show hierarchy
• names in bold represent keys
• the datatype of the value is shown in parenthesis after the key.
• an italic font is used to indicate types: string, integer, boolean, enumerated (values separated by a
‘|’ represent the set of allowed values).
• a missing datatype means that the value of the node is not used.
• square brackets indicate cardinality. If they are missing, a cardinality of [1..1] should be inferred.
10.2 System node
Some examples of system configuration settings nodes contained in the system node are shown in the
hierarchy below.
• system: information on system configuration settings
• site: Contains information about the site
• name (string): Name used to present this site to other sites. Used to fill comboboxes
or lists.

10.3 Harvesting nodes
All harvesters share a common set of nodes, which are retrieved by the harvesting engine for all harvesters. These common nodes are described in the hierarchy below.
• harvesting
• node
[0..n]
(geonetwork|csw|arcsde|filesystem|geonetwork20|oaipmh|

Notes
• this harvester uses two REST services from the GeoPortal API:
• rest/find/document with searchText parameter to return an RSS listing of metadata records
that meet the search criteria
• rest/document with id parameter from each result returned in the RSS listing
• this harvester has been tested with GeoPortal 9.3.x. It should be used for that version of GeoPortal
in preference to the CSW harvester.

User Interface
There are four different user interfaces on geonetwork:
• Classic - Perfect for hard environments, uses less javascript.
• Search - Uses the new widgets library. More responsive than the classic UI. Example Search
• TabSearch - Similar to the Search UI, but desktop-like as it uses tabs. Example TabSearch
• HTML5UI - Also based on widgets, makes use of latest web technologies.

11.1 Classic
This is the default user interface in GeoNetwork. It is a complete user interface with all the functionalities
the rest of the user interfaces have, but it is prepared to work on the hardest environments, using as less
javascript and Ajax as possible, for example.
You don’t have to do anything special to run this user interface, as it is the default one.
11.2 Search
To use this UI, you have to compile the web project with widgets profile activated, like: mvn clean
package -Pwidgets
227
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
11.2.1 Widgets
The GeoNetwork widget framework provides a list of independent pieces of code that let you build a
geonetwork user interface.
Add widget
Widgets are (usually) pieces of html that will be shown on your user interface. You should place them
in some html structure so they are visually arranged.
The widgets are prepared with some configuration options, so you can select some of the visual aspects.
For example, on the picture above, you an select the number of tags on the cloud or the number of items
shown on the “latest” section.
To add a widget you should wait for the page to be loaded. This may be approached with the onReady
function of ExtJS:
Ext.onReady(function() {
new GeoNetwork.TagCloudView({
catalogue : catalogue,
query : ’fast=true&summaryOnly=true&from=1&to=4’,
renderTo : ’cloud-tag’,
onSuccess : ’app.loadResults’
});
});
On this example, we just have to set up four properties on the constructor: the catalogue variable which
makes all , the query which will be sent to the server to provide the items to show, the renderTo id of the

div where the tag cloud will be drawn and the onSuccess function which will decorate and give style to
the results of the tag cloud search.
You can find the whole API of widgets here.
Create a new widget
You can create new widgets to add to your customized user interface. Using the same example as before,
you can see that you can easily create new widgets.
You just have to take care of two things:
• Visualization: define an html div where your widget will display information
• Manipulation of information: add some functionality (like a search connector) so the visualization
has data to show.
Using outside GeoNetwork
Although it is a testing functionality, in fact you can use this same widgets on your own webpage. You
just have to make sure that all dependencies are fulfilled and the settings are properly set up.
As development will go on, this functionality will be made easier and documentation will be filled up.
//TODO some simple examples

To use this UI, you have to compile the web project with widgets-tab profile activated, like: mvn

//TODO some simple examples
It contains two maps: preview map and big map. You can access the big map clicking on the preview
map. Both maps have synchronized layers, so if you add or remove (or change style) on one map layer,
you will see that the other map also changes.
Tested in Chrome, Firefox and IE>8 (also works but with some penalties on IE7).
Changing Style
Basic changing styling is pretty easy with this UI:
Colors
There is a file on web-client/src/main/resources/apps/html5ui/css/colors.css which contains all the colors
of the app.
Page design
The html is loaded from web/src/main/webapp/xsl/search.xsl This xsl is interpreted by jeeves and transformed to show the basic page. The page scheme is basically the same on all links, so if you change the
position of some html elements, they will be changed on all views.
Don’t forget that some of the elements are also placed with css.
Specific css for this UI (not shared with other UIs like search or tabsearch) is placed on webclient/src/main/resources/apps/html5ui/css/main.css
11.4. HTML5UI
235
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
Results view templates
They are on web/src/main/resources/apps/html5ui/js/Templates.js
Add more tabs
To add more tabs just look on search.xsl around line 240 (id=”main-navigation”) and add a new element
like this:
<li>
<a id="new-tab" href="//TODO">
<xsl:value-of select="/root/gui/strings/new-tab" />
</a>
</li>
The value of the string will be taken from the strings.xml file that corresponds to the language used.
Add a footer link
Look for the div element with id = “footer” and just add it:
<li>
<a href="http://geonetwork-opensource.org/">GeoNetwork OpenSource</a>
</li>
Maps and other elements: change display behaviour
Maps are always loaded even if they are not displayed. You can change this behaviour and allow (for
example) the big map to be shown at all times. This is the same for all elements you see that disappear.
To change this behaviour you should take a look at GlobalFunctions.js file. For each “view” you have
one function that shows it and hides it. You can change them to allow, for example, that the big map is
not hidden when results are shown:
• showBrowse
• hideBrowse
• showAdvancedSearch
• hideAdvancedSearch
• showBigMap
• ...
If you add a new “view”, you should update all this functions so the view is hidden or shown when
you want.
Settings
There are a few configurations of this user interface defined on two javascript files.
236
Chapter 11. User Interface
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
js/Settings.js
You can find here some global configuration settings for the UI. Usually you won’t have to change any
of them.
There are constants like:
• GeoNetwork.Settings.facetListConfig: used to configure the keywords for the facet search.
• OpenLayers.ProxyHostURL: (relative or absolute) path to url required by openlayers.
js/map/Settings.js
You can find here some specific map configuration settings for the UI. You can use this file to set up the
kind of projection and default base layers the maps will use.
There are constants like:
• GeoNetwork.map.PROJECTION: Basic projection for maps. EPSG 900913 by default.
• GeoNetwork.map.BACKGROUND_LAYERS: Base layers for the maps.
• GeoNetwork.map.MAIN_MAP_OPTIONS: Used by the constructor of the main (big) map.
• GeoNetwork.map.MAP_OPTIONS: When the user interface creates a new secondary map, it uses
this options on the constructor. Right now it works for the mini-map, but will be used on each
view a secondary map is shown.
Changing more complex features
Debugging
To debug javascript you only have to add a “debug” or “debug=true” parameter to the url like this:
http://....../srv/eng/search?debug
Adding more widgets
Widgets are usually added on the file /web-client/src/main/resources/apps/html5ui/js/App.js or one of its
children (see next section).
Global variable app
App.js creates the app global variable wich has (or should have) all the information needed for the app
to run.
It also initializes some secondary objects which contains information and loads more widgets:
init : function() {
this.initializeEnvironment();
// Initialize utils
this.loginApp = new GeoNetwork.loginApp();
11.4. HTML5UI
237
GeoNetwork Developer Manual, Release 2.10.3-SNAPSHOT
this.loginApp.init();
this.mapApp = new GeoNetwork.mapApp();
this.mapApp.init();
this.searchApp = new GeoNetwork.searchApp();
this.searchApp.init();
if (urlParameters.create !== undefined && catalogue.isIdentified()) {
var actionCtn = Ext.getCmp(’resultsPanel’).getTopToolbar();
actionCtn.createMetadataAction.handler.apply(actionCtn);
}
}
app.loginApp Should contain everything related to the authentication of the user like control buttons
to log in and log out and handles the cookie.
app.mapApp Should control everything related to maps. For example, if you want to add a new layer
to the maps you should look here.
Also initializes the maps (preview and big).
app.searchApp Closely related to Catalogue.js, it launches searches and initializes the results view.
To change the advanced search you have to look here too.
More info
History
The ExtJS History plugin is also used on this UI. It is not quite stable (not at all on IE) but it can be
modified to allow back button from browser to work.
What is the div id=”only_for_spiders”?
As the name says, this is for spiders or crawlers. When you access with the direct link to a metadata,
that div will be used to load plain xml data so browsers can process it. Don’t worry, if you are human
you will not see it at all.

The widgets are prepared with some configuration options, so you can select some of the visual aspects.
For example, on the picture above, you an select the number of tags on the cloud or the number of items
shown on the “latest” section.
To add a widget you should wait for the page to be loaded. This may be approached with the onReady

new GeoNetwork.TagCloudView({
catalogue : catalogue,
query : ’fast=true&summaryOnly=true&from=1&to=4’,
renderTo : ’cloud-tag’,
onSuccess : ’app.loadResults’
});
});
On this example, we just have to set up four properties on the constructor: the catalogue variable which
makes all , the query which will be sent to the server to provide the items to show, the renderTo id of the
div where the tag cloud will be drawn and the onSuccess function which will decorate and give style to
the results of the tag cloud search.
