DISCLAMER

This plugin has been tested with various CKAN servers (API v3 supported only), but we soon came to realize that each data portal implements its very own strategy for structuring metadata.

It is very likely that data from some servers cannot be browsed or downloaded!

References for the time being are:

• http://ckan.data.ktn.gv.at/api/3/
• https://www.data.gv.at/katalog/api/3/)

Pull requests that make such servers accessible (and don't break others) are welcome!
