[ckan-dev] spatial - csw server error

Mon Jul 29 15:47:19 UTC 2013

Hi Ryan,

Currently the csw interface offered by CKAN only exposes datasets that
were harvested from other CSW servers or WAFs, for which it has an ISO
representation. So if you create a normal dataset via the form or the
API it won't appear on the CSW endpoint.

Hope this helps,

Adrià
