URLs may apply to many cases but not necessarily all.
-- some identifiers are not resolvable by default, such as UUID
-- many identifiers have well-established convention by URI/URN registry,
such as urn:isbn or tel:, in these cases I don't think it's a good
practice to re-invent all of them in URL.
I think the case for ISBN is no big difference from telephone number or
zip code, etc. One may want to use good established practices instead of
having to create a URL for them.

Is it possible to enumerate other alternatives? I am not well familar with
all other choices, but I think both UID and URL have problems.
