PROF vocabulary terms needed for indicating classes constrained #44

Currently there is no way, in PROF, to say:

Class X has constraining elements in Profile Y

How do we say <Profile_Y> constrains <Class_X> ?

The motivation for this is that we want to be able to do a reveres look up to know what Profiles (Specifications) are relevant to what classes so that people can know, per class, what Profiles they should consider.

Suggested properties could be:

prof:constrains
    a owl:ObjectProperty ;
    rdfs:domain prof:Profile ;
    rdfs:range owl:Class ;  # or perhaps rdf:Resource
    rdfs:comment "A Profile constrains, that is places restrictions on the use of, a Class"@en ;  # ...of, a Resource
    rdfs:label "constrains"@en ;
.

prof:isConstrainedBy
    a owl:ObjectProperty ;
    owl:inverseOf prof:constrains ;
    rdfs:label "is constrained by"@en ;
.

@nicholascar Can you give some examples of classes being constrained? Thanks.

Certainly: the Australian Government Ontology Profile (AGOP: https://linked.data.gov.au/def/agop) requires that ontologies published by the Australian Government Linked Data Working Group have certain metadata present. This is enforced by the specification resource within that profile (https://linked.data.gov.au/def/agop/spec) that mandates that instances of owl:Ontology have skos:prefLabel, dcterms:created properties with certain values. The specification 's rules are testable against instance data (RDF files containing ontologies) by a validation resource written in SHACL.

So the constrained class here is owl:Ontology: for an instance of such to be valid according to AGOP, it must have such and such properties. Following the logic in this issue's description, we might say:

<https://linked.data.gov.au/def/agop> constrains owl:Ontology

Similarly, the VocPub Profile constrains skos:ConceptScheme but it also skos:Collection and skos:Concept...
