Maybe what we need to do is develop some use cases and see how
they would turn out. I'm less concerned about the cataloger view
than the user view. You've probably run into some description of
looking at FRBR from "bottom-up" vs. "top down." Some folks
consider the cataloger view to be bottom-up (from the thing in
hand to the Work) while the user view is top down (from the Work
to the item on the shelf).
Here are three items. I don't know if they are enough to
illustrate what worries me:

Based on the report of the FRBR aggregates group, I believe that
we would have:
Work 1 (#1, #2)
Expression 1 (#1, #2)
Manifestation 1 (#1)
Manifestation 2 (#2)
Work 2 (#3)
Expression 2 (#3)
Manifestation 3 (#3)
The latter is an aggregate work. Professor Wiesenmüller's
approach would create in addition something like (if I'm wrong
about this, shout out):
Work 1
has part1
Expression 1
Manifestation 3
Now, how to make this into something useful for the user.
Unfortunately we now have two Works that, as far as the user is
concerned, have pretty much the same content. One of the Works
points to all of the manifestations with the expression; one of
them points to one of the manifestations. This will look
redundant to the user. And I don't see how Work 2 can be removed
from display algorithmically. If we then add what is essentially
an analytic entry that links the non-aggregate Work 1 to
Manifestation 3, we're adding even more redundancy for the user.
The bottom line is that if every manifestation that has some
differences (prefaces, illustrations) becomes a separate Work,
adding MORE Work entities to clear this up will result in
duplicate entries from the user's viewpoint.
I'd love to be proven wrong on this.

Quoting Casey A Mullin <cmul...@stanford.edu>:
[Disclaimer: I haven't read the report yet, though it's waiting
for me on my desk]
To me, the desire/need to have WEM for an aggregate, as well as
W(EM) for some or all of the constituents, doesn't bring us back
to ISBD/MARC. In some cases (e.g., music sound recordings,
conference proceedings), the W and E of an aggregate is merely a
placeholder which allows us to describe the Manifestation as a
whole, while the constituent WE are the primary entities of
interest. But, even in those cases, it can be just as important
to describe the aggregate W too, say for purposes of assigning
subject terms, relating editors responsible for the compilation,
etc. I think WEM for both host and constituent entities always
exist; it's just that different types of resources call for
differing levels of fullness in describing each entity, ranging
from just identifiers (as Jonathan stated) to fleshed-out
records/graphs.
The bottom line IMO is that our cataloging and end-user
interfaces should suppress the entities that are of little
interest (i.e., minimally described) while allowing for
describing and navigating robust whole-part relationships as
needed.And this is definitely a far cry from what MARC allows.
Therefore, I don't see the same conflict that Karen does. We can
have our cake and eat it too. :)

Heidrun,
this is a really devilish problem, but I think the solution is
not going to be found within FRBR. That is because FRBR creates
a tight coupling between W, E, and M that (IMO) does not fit
the reality of publishing. In essence, nearly EVERY published
item is an aggregate - books have prefaces or illustrations
from other sources; musical recordings almost always include
more than one Work; serials are of course aggregates by their
nature. If each aggregate Manifestation is linked to an
aggregate Expression, and each aggregate Expression to an
aggregate Work.... well, then we have a one-to-one between
Manifestations, Expressions and Works. We're back to ISBD or
MARC in that case.
Then, if our assumption is that users are interested in the
individual Works as well as, or instead of, the aggregate, then
another entry has to be made for each individual Work as well.
I don't think that's how most of us envision FRBR.
I find there to be a conflict between the FRBR view and the
need to catalog a package. And I don't think FRBR resolves it
well, which is what the aggregate group struggled with. But
maybe the problem is deeper.

the people of the world (sadly), but that talented and

might enable the enlargement of that minority."
