As Karen notes, Publisher is not typically added as an authorized
heading in AACR2 cataloging, but it can be. There are authorities for
publisher names, and there is a MARC relator term/code (Publisher/pbl)
for this relationship, also authorized for RDA. The  Bibframe model
will need to accommodate this sort of thing--relationships that are
enabled for specialized use, not just the ones that are most common.
And it will inevitably need to accommodate relationships between
established entities and each kind of bibliographic object, however
those ultimately get sorted out and named.

Current MARC authorities are themselves a poor model for FRBR Work and
Expression entities in that MARC cannot express properties like
subject which FRBR says belong to these entities. I don't see any
effort in the early Bibframe model to argue for the appropriateness of
either the current authority data structure or the term "authorities,"
which is fine. Both currently reflect a focus on "authorized" heading
forms which promises to become a lesser component of the identified
entity representations we're moving toward with RDA. If "authority"
was used in the model document to give catalogers something familiar
to grab onto, maybe that wasn't such a good idea. Better to explain
more clearly where we've been and where we're going.

The Bibframe model's eliding of  FRBR works and expressions is
concerning, but I do welcome the comment that Bibframe expects to
distinguish types of works. This acknowledgment that Works (and by
implication Expressions) need to be sorted into types could help us
label work descriptions in a way that would let us say both that
Shakespeare's Romeo and Juliet is a work and that a resource which
aggregates Romeo and Juliet with an introduction, a critical essay, a
glossary, etc., is also a work, but an aggregate work (as FRBR 3.3
states), without sacrificing the ability to distinguish these two
types of work. They represent different levels of abstraction and
users searching for works should be able to specify which they
want--the thirty-some dramatic works Shakespeare wrote, or the
thousands of aggregate works centered on those thirty-some plays.
