I may be confused, but under the 303 redirect model are you allowed to
do multiple redirects. I know that under the HTTP standard you can do
as many redirects as needed provided a user agent is willing to follow
them all. but if the 303 is supposed to point from a
pseudo-real-resource URI to an information-resource then does it
chain? If it does then dealing with those extra mime types would just
be an issue for the application. Ie, replace application/rdf+xml in
the document with your favourite format and see if you get something
suitable back, else try again with your second-favourite format etc.

I think the "cool" thing about the URI's is that they don't require
the format to be a particular value inately, although it would be nice
if the resulting format that comes back the first time has links
directly to the other formats. ie, HTML with link rel=alternate etc to
avoid guessing which formats are available.

Cheers,

Peter

PS. Maybe I missed something also!
