Maybe as an appendix? Deserves a scholarly paper on its own. You've gone beyond what I meant. I wasn't suggesting that FRBR subsumes ir:..., or _vice versa_, rather that if people were finding the whole generalises/specialises thing tricky to get their heads around, then FRBR provides a useful detailed analysis of a _similar_ hierarchy or continuum in a related part of the (information) universe. > . . . > A page (or wa:Representation) can specialize *many* generic resources, > as Tim describes in his 1996 note.

Then ER diagrams are . . . misleading?

I'd > start with has mass => not information entity. Meaning you endorse that statement? So the Mona Lisa is not an InfEnt but your diagram is? How do you justify that? ht -- Henry S.
