It's not a bibliographic site per se, but Freebase has a pretty
comprehensive schema for book metadata.

https://www.freebase.com/book

They use "Book <https://www.freebase.com/book/book?schema=>" for the more
abstract level and "Book
Edition<https://www.freebase.com/book/book_edition?schema=>"
for the more concrete level, but they also abstract out a "Written
Work<https://www.freebase.com/book/written_work?schema=>"
set of core properties which can then be reused in the context of a
Poem<https://www.freebase.com/book/poem?schema=> (with
additional properties for meter, etc), Short
Story<https://www.freebase.com/book/short_story?schema=> or
Play <https://www.freebase.com/theater/play?schema=>.  The Book type
collects together Book Editions, but the bulk of the properties associated
with works are on Written Work.

Another thing they do differently is have a separate Cataloged
Instance<https://www.freebase.com/media_common/cataloged_instance?schema=>type
to hold ISBN numbers so that things like periodicals with ISBN numbers
don't have to be called "Book Editions."  The Media
Common<https://www.freebase.com/media_common> domain
which contains Cataloged Instance also contains other generally useful
types like Adaptation<https://www.freebase.com/media_common/adaptation?schema=>/Adapted
Work, Translation/Translated Work, Publication/Published Work (to connect
together works in a collection, etc)

This is a more fine-grained model than is used today for books, but my
personal hope is that at some point in the future we can use the energy
freed up by not re-cataloging the same item 18 different times to do richer
and more detailed cataloging in those areas where it's appropriate.
