[ckan-dev] OpenSearch

Wed Feb 3 16:54:46 UTC 2016

If by "add" you mean "create", then all CSW-related tables must be created
in advance.

In our case, we do it using some custom Paster commands when setting up the
extension.

In your case (since you dont install the whole extension), you can find all
ORM table definitions at
https://github.com/PublicaMundi/ckanext-publicamundi/blob/master/ckanext/publicamundi/model/csw_record.py.

So, you can use standard sqlalchemy tools to initialize this part of the
database schema, i.e create the needed tables/indices.
