URN + URV = URL
and that a URL refers to a single instance of a document at a single
locatation.
Although there may be some use of a URV within hypertext (and other
links), I would think that the typical case would be to just use an
unadorned URN, since I wouldn't know which variant would be wanted until
retrieval time. It would seem that some sort of negotiation/protocol
would be useful here, even something as simple as what Gopher+ does
(return list of all variants/views). This would allow for smart clients
to do the negiotiation.
As long as the URV is extendable, this looks like a good idea. I would
opt for just 2 dimensions within the URV right now, location and format.
I also remember a proposal for a URM (modifier). Would this work for
the URV?
