There's currently an inconsistency between the MIME type registration:
Additional information:

           Magic number(s): none

              Although no byte sequences can be counted on to consistently
              identify RDF, RDF documents will have the sequence "http://
              www.w3.org/1999/02/22-rdf-syntax-ns#" to identify the RDF
              namespace.  This will usually be towards the top of the

           File extension(s): .rdf

           Macintosh File Type Code(s): "TEXT"

and the RDF syntax specification:
It is recommended that RDF/XML files stored on Macintosh HFS file systems 
be given a file type of "rdf " (all lowercase, with a space character as 
the fourth letter).

Not being a Macintosh user, I don't know which is better, but I think the 
specs should be consistent.
