I just changed this to void:Dataset actually - though we have a similar
problem - void:Datasets are supposed to be only for datasets available
in RDF, as most of these are not... I'm leaning towards dcterms:Dataset.
On the categories, I agree we need to think it through more. I'm not
certain what best practice is here (and there seems to be a last of
BCP type docs in the RDF world...)
I'm happy to work through this with you though, and also have some
involvement with the data.gov.uk project, which needs its CKAN instance
rendered as RDF, so this is relevant there too.
for the current version of what Rufus pastied (there's an RDF/XML link
on the page now as well.
