Although 302 is generally wrong, it is implemented right:
http://lists.w3.org/Archives/Public/public-swbp-wg/2006Jan/0076.html

 The temporary URI SHOULD be given by the Location field in the
   response. Unless the request method was HEAD, the entity of the
   response SHOULD contain a short hypertext note with a hyperlink to
   the new URI(s).

Actually, -I is a head request so the first request shouldn't contain any 
content. Besides that the second request (200 OK) returns "Content-Type: 
application/rdf+xml" 

The problem with 302 and purl.org is very old and probably unresolved (please 
research, start here: 
http://lists.w3.org/Archives/Public/public-swbp-wg/2006Jan/0076.html)

Linking can't be verified because of no SPAQL endpoint found.
