The default representation if no extension is specified is a normal web 
page. I guess you could try to do something with content negotiation, 
but I'd rather not rely on that. On the other hand the page could 
include something like:

   <link
     rel="alternate" type="application/rdf+xml"
     href="http://uniprot.org/entry/P12345.rdf"
   />

Haven't given that much thought yet.

Note that if you actually entered http://uniprot.org/entry/P12345.rdf, 
you would be forwarded to some other site that is capable of serving the 
resource. Since these URLs are not really as stable as they should be, I 
prefer to use URNs for identifying resources, e.g.

   urn:lsid:uniprot.org:uniprot:P12345

This also avoids confusion with users who always expect a URL to be 
resolvable...
