Configuring Alternate CSW Backends¶

pycsw is the default CSW server implementation provided with GeoNode. This section will explain how to configure GeoNode to operate against alternate CSW server implementations.

Supported CSW server implementations¶

GeoNode additionally supports the following CSW server implementations:

GeoNetwork opensource

deegree

Since GeoNode communicates with alternate CSW configurations via HTTP, the CSW server can be installed and deployed independent of GeoNode if desired.

Installing the CSW¶

GeoNetwork opensource Installation¶

Deploy GeoNetwork opensource by downloading geonetwork.war (see http://geonetwork-opensource.org/downloads.html) and deploying into your servlet container

Follow the instructions at http://geonetwork-opensource.org/manuals/2.6.4/eng/users/quickstartguide/installing/index.html to complete the installation

test the server with a GetCapabilities request (http://localhost:8080/geonetwork/srv/en/csw?service=CSW&version=2.0.2&request=GetCapabilities)

See http://geonetwork-opensource.org/docs.html for further documentation.

deegree Installation¶

Deploy deegree by downloading the deegree3 cswDemo .war (see http://wiki.deegree.org/deegreeWiki/DownloadPage) and deploying into your servlet container

Create a PostGIS-enabled PostgreSQL database

Follow the instructions at http://wiki.deegree.org/deegreeWiki/deegree3/CatalogueService#Run_your_own_installation to complete the installation

test the server with a GetCapabilities request (http://localhost:8080/deegree-csw-demo-3.0.4/services?service=CSW&version=2.0.2&request=GetCapabilities)

See http://wiki.deegree.org/deegreeWiki/deegree3/CatalogueService for further documentation.

Customizing GeoNode CSW configuration¶

At this point, the CSW alternate backend is ready for GeoNode integration. GeoNode’s CSW configuration (in geonode/settings.py) must be updated to point to the correct CSW. The example below exemplifies GeoNetwork as an alternate CSW backend:

# CSW settings
CATALOGUE = {
    'default': {
        # The underlying CSW implementation
        # default is pycsw in local mode (tied directly to GeoNode Django DB)
        #'ENGINE': 'geonode.catalogue.backends.pycsw_local',
        # pycsw in non-local mode
        #'ENGINE': 'geonode.catalogue.backends.pycsw',
        # GeoNetwork opensource
        'ENGINE': 'geonode.catalogue.backends.geonetwork',
        # deegree and others
        #'ENGINE': 'geonode.catalogue.backends.generic',

        # The FULLY QUALIFIED base url to the CSW instance for this GeoNode
        #'URL': '%scatalogue/csw' % SITEURL,
        'URL': 'http://localhost:8080/geonetwork/srv/en/csw',
        #'URL': 'http://localhost:8080/deegree-csw-demo-3.0.4/services',

        # login credentials (for GeoNetwork)
        'USER': 'admin',
        'PASSWORD': 'admin',
    }
}
