[ckan-dev] Middleware-components

Hello David,

I'm mostly interested in exact data and not metadata.
I want to import data into the datastore from various sources such as other PostgreSQL, Oracle, Window Shares, FTP etc.

Henrik,

Yes there are a number of CKAN harvesters around that cover the main metadata formats (DCAT/data.json, GEMINI/ISO19139). You can write custom harvesters for the databases you mention, and manage them using the web interface. Check out ckanext-harvest for more info.
