Karen, Well, I'm clearly way behind on my email, but I find the idea of a recordless view intriguing and presumably much more flexible. I have been playing with E-R modeling for moving images in the modified version of FRBR that OLAC (online Audiovisual Catalogers) has been discussing. The thorniest areas so far are linking where there are gaps in information, scenarios where is seems like we want different amounts of detail under different scenarios, and dealing with parts of entities, although it may just be that I am going about this the wrong way. The model cases are simple, but the real data is messier and seems to have more levels. It's harder for me to intuitively get my head around how a model based just on statements would work in practice, but it does sound like it would deal better with gappy data, which is what we'll have. I'll be interested to see what you come up with.

Which is why I'm exploring the possibility of a "recordless" view -- which would consist of short statements ("Jane is author of Book") that are each valid, and can be combined with other statements to build up to a complete bibliographic description. I don't know yet if this is possible. It would use semantic web concepts, not the RDA scenario 1, but perhaps scenario 0. It assumes an open bibliographic environment where statements can exist with metadata contributed by others. If I get a clear enough picture in my head, I'll make a drawing! kc
