[ckan-dev] CSW, ISO and Spatial Extension

Thu Nov 1 08:43:12 UTC 2012

Hi Ryan,

It is true that pycsw handles the xml files in the db and we only map 
the queryables in our tables and not the full ISO implementation. This 
was a decision we made initially when we started pycsw in order to 
support multiple metadata formats under the same db schema.

I haven't tested against a view table but I feel it will work ok.

Please feel free to ask your questions about pycsw.

Thanks,
Angelos
