[ckan-dev] questions on resources import / export

[Emanuele Tajariol]

Hi Elena,

in a couple of deploy we did, we used CKAN and GeoNetwork in the same node.
CKAN is used as user frontend, and publishes both geo and non-geo datasets.
GeoNetwork is used for CSW access.
CKAN harvests the geographic metadata from GN using CSW, while the non-geo 
dataset are edited directly on CKAN. Geographic metadata are of course edited 
on GeoNetwork.

If you have different catalogues that should interact, it's usually a good idea 
to use existing standards (CSW for geographic datasets, for instance).
Using internal formats (such as querying Solr) may be more efficient, but then 
you would be tied to a specific version of the application and its internal 
model; some more work would be needed every time internal formats change. 
Just my 2¢ :)


   Cheers,
   Emanuele
