The definition is indeed vague to the point that making two entities alternates seems arbitrary. To me this means that one can always assert the equivalence amongst two entities if *you* think they are aspects of the same thing, just like one can assert owl:sameAs, and then live with the consequences. For instance a alternateOf b b alternateOf c a specializationOf c would not be consistent if you do the reasoning. --Paolo On 9/25/12 8:15 AM, Luc Moreau wrote: > Hi all, > > Can someone make suggestions regarding "how to determine when two entities are considered alternates of each other, or when they > are not". > > Our definition states "Two alternate ◊ entities present aspects of the same thing.
