Re: [dxwg] Options for metadata to describe tabular data in a more structured way? (#1418)

The "correct" approach according to the scoping discussions would be to define a profile of DCAT that defines a canonical structural description. RDF-QB is probably the leading candidate for such a description - and the StatDCAT-AP profile is a potential starting point  see : https://joinup.ec.europa.eu/collection/semantic-interoperability-community-semic/solution/statdcat-application-profile-data-portals-europe/release/100

The question is whether there should be a profile heirarchy:
1) DCAT-QB profile of DCAT and QB for any structural case (not just statistical data) 
2) StatDCAT being a profile of DCAT-QB
3) StatDCAT-AP being a profile of StatDCAT and DCAT-AP

(this would make simple declarative statements about the expected interoperability as well as provide logical extension points for new profiles to suits any similar requirements without re-inventing these patterns.)

For each profile SHACL validations, JSON schema, JSON-LD contexts etc to support all these could be implemented in a modular fashion to simplify implementation.  (This is just extending what the DCAT-AP community is already doing toward a scalable approach to support machine access and readability of interoperability requirements.)

Note that publishing profiles of DCAT is explicitly out of scope of this working group - but there must be a sizeable community who would have an interest in doing that in a coherent way - it would be helpful if the DXWG could pass off these matters to an appropriate forum.
