1.       *DCAT vocabulary*   = "DCAT core".
I used the latter term to emphasise that DCAT vocabulary should only have
generic core terms

Agree also we dont need to define profiles, but IMHO its not useful to
leave it as vague wording about "write a document" - we need to provide an
example of a specific coded profile - even if we dont publish that as a
profile ourselves. Effective guidance means a tested mechanism that meets
requirements for profile specification, and has pedagogical examples.

Also I think there remains deep confusion about the nature of a profile -
it should describe one of many possible "interfaces" not a single concrete
implementation - it not analagous to a schema  - i.e. we could "suggest" a
profile that only specifies use of Prov-O to describe data provenance. We
don't need to boil the ocean by describing every aspect of every possible
use within a monolithic single profile, not withstanding the tendency of
people to create massive human readable documents and then clone and hack
these to specialise every single aspect in a single artefact. Thats just
getting sidetracked by the limitations of the documentation mechanisms (PDF
documents are inherently monolithic). We dont need to adhere to the
mistakes of the past, however well intentioned.
