Does an official URN for the MIME type exist?
Mozilla Firefox and other applications use notations like "urn:mimetype:text/plain
" or "urn:mimetype:handler:text/plain
".
There are two problems with this approach:
No "mimetype
" namespace exists according to the IANA's official registry (http://www.iana.org/assignments/urn-namespaces/). Thus, only "urn:x-mimetype
" would be a valid namespace (according to RFC 3406 section 4.1).
The slash "/
" may not be used in URNs according to RFC 2141 section 2.2. But it could be encoded to "%2F
".
All that considered, is there another way to represent the MIME type "text/plain
" as an URN than "urn:x-mimetype:text%2Fplain
"?
[UPDATE: Thinking about it, an URI would be ok too. But I can't find no URI for MIME type neither.]
Thanks

FYI, I read the presence of /
as a SHOULD NOT by RFC 2141, rather than a MUST NOT.
For this approach I would just use the URI of the assignment, e.g. <http://www.iana.org/assignments/media-types/application/zip>. The only caveat is that not all of them dereference. If you can live with that though, you should be OK.
