Main purposes:
- Handle some GeoNetwork specific coding (e.g. OGC:WMS* protocol in
onlineResource
maps to the specific wmsformat
in CKAN) - Provide mapping from GeoNetwork categories into CKAN groups
- Some schemas provide GML elements with the old namespace URI
http://www.opengis.net/gml
while the standard CKAN CSW harvester parses elements with thehttp://www.opengis.net/gml/3.2
namespace. This harvester enables both URIs. - Since GeoNetwork provides also front-end services, the harvester may build some extras fields containing URL pointing to well-known services (e.g. the extra value
gn_view_metadata_url
will automatically be created with a value of the related entry in geonetwork:http://yourgnportal/geonetwork/srv/it/metadata.show?uuid=arw_3km_High_cloud_cover_HCY_20150323T000000000Z
).
