Do we need domain/range for playsRole/roleOf

[dr-shorthair]

and do we need a audata:Agent class to support this?
Or do we use restrictions?

[dr-shorthair]

For reference, in PROV the role properties have domains, as follows:

prov:hadRole
rdf:type owl:ObjectProperty ;
rdfs:comment "The optional Role that an Entity assumed in the context of an Activity. For example, :baking prov:used :spoon; prov:qualified [ a prov:Usage; prov:entity :spoon; prov:hadRole roles:mixing_implement ]."@en ;
rdfs:comment "This property has multiple RDFS domains to suit multiple OWL Profiles. See <a href="#owl-profile">PROV-O OWL Profile." ;
rdfs:domain prov:Influence ;
rdfs:domain [
rdf:type owl:Class ;
owl:unionOf (
prov:Association
prov:InstantaneousEvent
) ;
] .

The inverse ("wasRoleIn") is not actually included in PROV, though the name of the property is reserved.
