Re: PROV-ISSUE-262 (qualifier-property): entity used entity? [Ontology]

Yes, I raised this on the mailing list the other day as well.
If we delete the subclasses of qualified, then we allow this kind of
assertions. On the other hand,
if we add subclasses for every involvement the model gets more complicated.
If we finally decide to add the subclasses, I wouldn't name properties the
same way as their classes
(as in usage and Usage), because it gets confusing. I like the "hadUsage",
but Tim wasn't very happy
about it.
