Do we need a mean to specify that two BOB are characterizations of the same entity? 

In the initial draft, I think that the editors intentionally avoided defining the term "entity" as part of the vocabulary. I don't suggest defining that term, but having a means by which one would know that two Bobs are characterizations, possibly different, of the same entity, e.g., using an assertion like "sameEntity(bob1, bob2)".

I think this will be useful, amongst other things, in the definition of IVPof.
