Within its harvesting model CKAN now has an Open Geospatial Consortium®
(OGC) Catalogue Service Web (CSW) client, which provides support for
harvesting GEMINI2 documents from CSW servers.
That means CKAN can now pull geospatial metadata from tools like
GeoNetwork and ArcGIS.
CKAN can also harvest GEMINI2 documents from Web accessible folders, and
from individual files.
A minimal server CSW interface will be implemented in the Spring.
The CKAN's CSW server interface is not planned to be a full
implementation of CSW, just the capabilities needed to make it possible
to harvest geospatial metadata using CSW.
Then, it will be possible to harvest geospatial metadata from CKAN using
tools like GeoNetwork and ArcGIS.
CKAN package extras with be used to store the GEMINI2 attributes: West
Bounding Longitude, East Bounding Longitude, South Bounding Latitude,
and South Bounding Latitude. Spatial searches will use those attributes.
Other geospatial attributes of GEMINI2 will also be stored in a
package's extras, such as Extent, Spatial Resolution, Equivalent Scale.
