Great! Now we can do some harmonization work! Some questions:

You use scovo:Dataset. As I interpret the scovo definition of Dataset
[1] these are only supposed to be statistical datasets?

Categorisation is expressed with doap:category. The definition of
doap:category [2] suggests that it is the "category of a project" (and
has rdfs:domain doap:project) which may seem inconsistent when dealing
with datasets?

I CC:ed him in this email. I am swamped with work next week and will
be in Avignon throughout March with limited connectivity. I'll get
back to you as soon as I'm back.

But your front page says "CKAN is a registry of _open_ data and
content packages."? Anyways, that was good to know because then I'll
try to make sure you can get all the swedish datasets I have found.
