[ckan-dev] questions on resources import / export

Wed Oct 23 16:23:42 UTC 2013

I agree with Emanuele, CKAN and GeoNetwork, although sharing some
functionality, are different tools with different audiences.
A good project will choose the right tool or integrate different tools
to provide the best solution to its use case.

Big +1. Any feedback that you can report to the project will be
useful, even negative.
