Can of worms indeed :P

Certainly agree that it is out of scope for the group. I only
mentioned it because it seemed closely related to things that I was
thinking about. One of my motivations was/is to find a use for
reasoning that was common enough to become compelling - considering
that RDF is reasonably widely used a publishing format but almost
nobody actually uses inferencing. So how can we use logic to help
improve the quality of published RDF? By finding bugs, where "bug"
usually means "entails a contradiction". That said, I wouldn't
necessarily argue for moving owl:disjointFrom into RDFS (is bigger
impact a good or a bad thing?) nor owl:sameAs (because it is misused
almost to the point of meaninglessness in practice), but would support
including owl:inverseOf because it seems in a hand-wavy way to belong
to the same class of predicates that are already in RDFS.

Cheers,
