Ed, I realize that. I am questioning using a non-intuitive example when
first presenting BIBFRAME to librarians. Obviously, what is there is
supposed to be just an example, not a complete vision of what BIBFRAME
could some day be. If you only show a few authorities as examples, using
ones that are rare from the view of most librarians might not be the
best case.

Publisher-supplied metadata (ONIX for Books) may include publisher identifiers drawn from a variety of standardized code databases, such as GLN, SAN, ISNI, as well as library authority metadata (LCCN) (See ONIX Code List 44). Such metadata (and authorities) may be linked to a BIBFRAME Instance via a common ISBN.
