Re: [dxwg] prof:profileOf sub-property of prov:wasDerivedFrom (!?) (#485)

profileOf means that all constraints of the base specification are
transitively inherited - this does not imply that this inheritance is
described axiomatically.  Constraints languages may support such axioms,
but for now its a significant step forward to be able to declare these
dependencies and to find and classify related resources.

As it seems a consistent challenge to keep separate issues of expressivity
of constraint languages from description of a profile perhaps we should
introduce a new tag:  "constrain-language" for those issues, then we can
deal with these in the profile guidance document.  It also highlights the
potential nature of Profile as a sort of dcat:Resource - at least thats the
way it can be thought of -  its a thing with some specific relationships we
want to have very particular meanings (i,e. inheritance of constraints) but
it otherwise describable using standard vocabs - dcat, dc, prov etc.

the profile guidance document cant at this stage point to a constraint
langauge that handles the inheritance axiomatically, so a combination of
the profile ontology and a constraint language of your choice can carry the
information, and implementations will need to work out how to handle the
inheritance - for example requiring that each profile is published with a
resource that defines the full set of constraints, or requiring that all
inherited constraints are satisfied independently.
