Investigate whether this should be on vocabulary, vocabulary entry, both, and/or possibly on a more general element as well.

There may also be an impact on the ontology, depending on the resolution.

This might be a new area of exploration, and could apply beyond MVF entries in the context of MVF.

Currently the metamodel reflects SKOS-like relations such as broader and narrower, but more is needed for certain applications.

It would be useful to have a non-normative annex demonstrating how one could do this as a starting point for MVF users.
