Karen: Jon, obviously I'm with you on the "cataloging system v. linked data world" -- but I'm not convinced that FRBR "graph" does the job. Although Murray and Tillett go to great lengths to dispel the notion of "hierarchy" in their presentation they do not address the dependency issue. (see slide 137) As Jeff said, FRBR has taken something like "book" and broken it into 4 interdependent parts. While it may not be a strict hierarchy, the FRBR model only allows a linear set of relationships between WEMI, multiple though they may be, and you need all of the intervening levels to have a whole. When you see the slides where they are building up the levels of abstraction, there is never the hint that not all of those levels will be there. None of their many complex examples show one with a "missing" level. This is Barbara's "thinking like a cataloger". In the real world you might have an ISBN (M) and an author (W) and nothing else. This is inconceivable in the world of library catalogs, and I don't see any way to model this in the Murray/Tillett method. -- Tom Baker <tbaker@tbaker.de>
