Hi Jonathan

CKAN is a great and clean resource I was not aware of. Shame on me!
BTW just corrected the package http://www.ckan.net/package/read/lingvoj 
which was written *linkvoj*.
Actually that was a great typo, I should have thought of it when 
creating the resource, too late now, cool URIs don't change.
And along with the current debate on LOD licensing, it figures I should 
clarify the license, but the arguments are very arcane from my non 
anglo-saxon non-lawyer viewpoint I must say.
So basically just waiting for reliable people to tell me : just do that, 
it's the best practice :)).

On a more general level, great idea to have a RDF description of the 
packages. Which ontology would you use? Seems do me that DC terms 
descriptions should be easy to do to begin with.
