Audio dramas are a separate product, if we are looking at this from a
product point of view. As you mention, they are often the result of a
broadcast, and that may be the more important aspect, "product-wise."
Audiobooks are a major product of their own, as witnessed by the
purchase of Audible.com by Amazon. Given the general thrust of
schema.org, I believe it should be in a category of its own.

Actually, audiobooks refer variously to "reader" "read by" "narrator"
and "narrated by". There is a significant difference between reading
every word (albeit with some actorly inflection and differentiation of
voices) and "performing." I do wish there were someone here from the
audiobook business, but I suspect that "performer" would not be seen as
appropriate for audiobooks.

Audiobooks have their own copyrights and their own copyright holders,
and these are separate from the copyrights on the printed book. The
bibliographic data should represent the audiobook, not the print book it
is read from. The publisher of the print book does not hold the
copyright in the audiobook, but they have a contract with the audiobook
producer that allows them to create the audiobook product. This is not
unlike the licensing of a book to be made into a movie. The movie
copyright is separate from the book copyright.

BTW, the copyright designation for sound recordings is (p), not (c).
You'll see this in library data:

Imprint 	New York : Listening Library, p2007

This is also true for all re-publications of books, as you see if you do
a search in any large bibliographic database. The date of publication is
... the date of publication. There are hundreds of publications of Moby
Dick after 1851, and the metadata for each one contains *solely* the
date of publication of the "re-publication." I would love for
bibliographic data to contain an "original date of the work" (which,
BTW, you can find in Wikipedia entries for creative works), but in
bibliographic metadata that information is not included since it
requires some research on the part of the metadata creator.

I can understand the desire to connect the audiobook and the print book
which is being read. In most catalogs and databases they "connect"
because they have the same author, title and subjects, so they are
retrieved with the same query and may be merged in display (cf. Amazon
displays). I'm not sure that the data that exists will lend itself to
providing the information to support isBasedOnUrl. This becomes a
question of goals, therefore: to provide schema.org properties for
current data, or to make schema.org into a schema that allows new
metadata to be created. I admit that at the moment I'm more interested
in the former, since I see a first use case for schema to mark up
existing data. I'm not seeing it as a metadata creation schema. Perhaps
others are aiming at the latter?
