CKAN spatial extension
######################

CKAN does not support spatial information in its core code.

There are 2 plugins that will make CKAN integrate with CSW catalogs. 

Harvest extension
   The harvest plugin provides a basic frmaework for managing harvesting jobs.

Spatial extension
   Spatial plugin extends the CKAN model to provide some spatial functionalities.
   In particular, we'll use the CSW harvesting capabilities to harvest data from a 
   GeoNetwork instance, and the mapping/model extension to map ISO19139 metadata into 
   CKAN model.   
   https://github.com/okfn/ckanext-spatial


CKAN harvests GeoNetwork metadata using the CSW protocol, asking for metadata in ISO19139 format.
Such metadata shall be converted in a format suitable for CKAN (as described in next section :ref:`mapping19139`)
and then ingested.
