Re lists and deliverables...

This is actually not a trivial issue - for each requirement there are
multiple possible ways to deliver - i.e. should it be promoted to an
extension of DCAT or is there an existing vocabulary we should re-use and
hence it should be in the guidelines.  In fact, there are probably
formalisms of DCAT profiles we can/should deliver, at the very least to
support with exemplars and experience the guidelines for how to profiles.

So I suggest the triage might be:

Look at each requirement and decide if a case can be made for all the extra
work of a DCAT extension,  and if not, can a top-level general profile be
identified - i.e. should we propose a DCAT profile for scientific data (and
then delegate it to either a keen subgroup to add as a deliverable, or
describe the potential scope in the guidleline deliverable and then park
the issue)?

Only generally applicable cases should make it into DCAT core. Maybe we
should create a register of possible abstract profiles, (which would be
refined for specific application domains) where external vocabularies we
decide we want to exploit are introduced - e.g. DCAT -PROV .  Note that
profiles describe conformant subsets, and are thus not disjoint, so
something can be both DCAT-Prov and DCAT-EU, so this is a matter of high
level functional requirements, not a binning/classification exercise.
