There's no process for W3C to do track this as far as I see and the process from the IETF side is rather opaque to me, apart from email the ietf-types list for advice/feedback, which does not seem to be authoritative. > Once the registration is official, we should also submit a patch to the > Apache httpd project to get common file suffixes for RDF serialisations > into the Apache default configuration files.

Yes, it got added since RDF/XML registration was approved by IETF types and the Apache project made the change. > It would be handy to add: > > AddType application/rdf+xml .owl A bad idea I think, format should have one mime type. (Aside #1: Alternative: have app/rdf+xml+owl or app/rdf+xml+owl[1-8] for each of the 3 OWL1 & 5? OWL2 varieties, if you must. Mixing the vocabularies in with the formats is a mistake, where do FOAF, DC, RDFS, ... and versions of those get recorded? Summary: don't go there. ) > AddType text/n3 .n3 > AddType text/turtle .ttl > AddType text/plain .nt # Or maybe use text/turtle here too? It would be good to get the turtle one done. The major subtlety here is default encoding. N-Triples is always ASCII, Turtle is always UTF-8. So text/plain is fine for .nt and it does not need a registration. (see http://www.w3.org/TeamSubmission/2008/SUBM-turtle-20080114/#sec-mediaReg ) Aside #2 - I think it's about time for an updated Turtle to fix typos, clarifications. So maybe we can ask again at that point. Dave
