Configuration du CSW

Afin de configurer le serveur CSW vous devez être connecté en tant qu’administrateur. Ouvrir la section « Paramètres » de la page d’administration et sélectionner « Configuration du serveur CSW ».

The CSW service provides a description of itself, the human who administers it, and other information through a GetCapabilities request (eg. http://localhost:8080/geonetwork/srv/en/csw?request=GetCapabilities&service=CSW&version=2.0.2). This form allows you to configure the CSW server and fill out some of the properties returned in response to a GetCapabilities request.

Configuration options:

  • CSW Enabled: By default CSW endpoint is enabled, but it can be disabled.

    The Open Geospatial Catalogue Service for the Web (OGC-CSW) service, is a self-describing service that allows query, update and insertion of metadata records.

  • Record to use for GetCapabilities: The capabilities document is created using the record selected here.

  • Inserted metadata is public: By default, metadata inserted with the CSW Harvest and CSW Transaction operations is not publicly viewable. A user with the appropriate access rights could do this after the CSW Harvest and CSW Transaction operations, but this is not always convenient. If this option is checked all metadata inserted using the CSW Harvest and CSW Transaction operations will be publicly viewable.

  • Create element if it does not exist when using XPath in CSW transaction.: If not checked, only existing elements can be updated.

Service Metadata Record

In order to create a custom capabilities, it is recommended to create a dedicated service metadata record (using ISO19115-3 or ISO19139 standards). This record is used to build the capabilities document using the template source file web/src/main/webapp/xml/csw/capabilities.xml.

When creating such record, the following information will be used to create the capabilities:

  • title

  • abstract

  • keywords

  • fees (from Distribution > ordering instructions field)

  • Access constraints (from Access constraints > Other constraints field)

  • Contact (from Identification > First point of contact)

The service record MUST be public.

If an error occurred while building the capabilities document from the service record, a WARNING is reported using a comment and the default capabilities is used:

CSW Configuration for INSPIRE

If your catalogue also focus on INSPIRE (see Configuring for the INSPIRE Directive), it may be relevant to also populate the following to properly configure your discovery service:

  • metadata language (+ additional languages if any) (use for SupportedLanguages, DefaultLanguage)

  • INSPIRE themes

  • temporal coverage

  • metadata contact

  • metadata conformity regarding Commission regulation 1089/2010

With this information the CSW can be validated using the INSPIRE validator.

CSW post processing

In some situation, user may want to modify XML encoding of records when retrieved using CSW. For example:

For this, user can add extra conversion step during output of GetRecords and GetRecordById operation:

  • Adding post process to srv/eng/csw by creating for each output schema a file eg. for gmd, present/csw/gmd-csw-postprocessing.xsl

  • Adding post process to a portal inspire/eng/csw by creating for each output schema a file eg. for gmd, present/csw/gmd-inspire-postprocessing.xsl

For a portal INSPIRE, create an « inspire » portal in the admin > settings > sources. User can then setup a post processing phase for the INSPIRE CSW of the portal. Create a post processing file gmd-inspire-postprocessing.xsl in yourschema/present/csw folder. The following example, remove contact with no email and link not starting with HTTP to conform to INSPIRE validator rules.

The service can be tested with:

curl 'http://localhost:8080/geonetwork/inspire/eng/csw' \
  -H 'Content-type: application/xml' \
  --data-binary $'<csw:GetRecordById xmlns:csw="http://www.opengis.net/cat/csw/2.0.2" service="CSW" version="2.0.2"                   outputSchema="http://www.isotc211.org/2005/gmd"><csw:ElementSetName>full</csw:ElementSetName><csw:Id>3de9790e-529f-431f-ac4f-e86d827bde8e</csw:Id>\n</csw:GetRecordById>'
