Following up, the related work on roles in this paper[1] is somewhat
helpful for thinking about this.

I wonder if we actually want to define roles as relations between an
instance of a relation and the entity.

This way we would have the relation prov:role and would make
subproperties of it to define new relations.

For example, instead of

wasAttributedTo(doc, bob, [ prov:oRole="editor", prov:sRole="bestPaper" ] ])

we would have

wasAttributedTo(id1; doc, bob)
role(id1, doc, [prov:type="bestPaper")
role(id1, bob, [prov:type="editor)

Anyway, just a thought...

Paul
