Re: Using DCAT for RSS

Phil,

I agree. Often for a project there are good reasons to cut short on the
usage of vocab elements.
A choice that every data creator/provider takes on its own.
For those who care to create highly reusable data, it is still worthwhile
to discuss and document the conceptualization
and provide clear distinctions and examples. The Amsterdam event sounds
very interesting  :)

Cheers, Marcel
