--- correct. With things like Reviews we choose to create hReview and
not hBookReview or hConcertReview. ISBN is a unique identifer, UIDs
solve this problem.

--- much akin to IM names, we can also explore using the protocol to
describe the TYPE.
<a href="isbn://123456">A book</a>

correct, UID is a subset of hCards just like Opening-hours is a subset
of hCalendar. I think we should NOT further fragment UID into
ISBN/ISSN/XYZ they are all Unique Identifers. We SHOULD make the UID
page more 'findable' and it should encompass things such as ISBNs, but
i don't think we need to duplicate efforts for each individual TYPE of
UID. We don't have individual pages for TEL TYPE FAX so why have pages
for UID TYPE ISBN? By keeping all the UID types together at the UID
page we can (hopefully) help the next person find information better
when they want to mark-up things like their Nintendo DS code for the
world to see, or other unique identifers. Things like MD5 and SHA-1
hashs for downloads also fall into the category of UID and NOT their
own formats.

This is certainly worth exploring, but re-use is best.
