    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.
