I intend to submit the following media type registration to the IESG for registration with IANA. However, before then I would welcome community review and feedback on the proposed registration. If you see any problems, please let me know. Assuming that the appropriate form for such a media type registration would be an RFC-style document I wrote one up using the xml2rfc syntax and published it here: http://www.isotopicmaps.org/sam/xtm-rfc.html The actual registration part is included below. --------------------------------------------------------------------- This is a media type registration as defined in RFC 4288, "Media Type Specifications and Registration Procedures" [RFC4288]. *MIME media type name:* application *MIME subtype name:* xtm+xml *Required parameters:* none *Optional parameters:* charset Same as charset parameter of application/xml, defined in RFC 3023 [RFC3023]. *Encoding considerations:* Same as encoding considerations of application/xml, defined in RFC 3023 [RFC3023]. *Security considerations:* See Section 5. *Interoperability considerations:* _NEED TO WRITE THIS PART_ *Published specification:* See the Topic Maps Data Model [ISO13250-2] and the XTM specification [ISO13250-3]. *Applications which use this media type:* XTM is device-, platform-, and vendor-neutral and is supported by a range of applications and web services. *Magic number(s):* none Although no byte sequences can be counted on to consistently identify XTM, XTM documents will have the sequence "http://www.topicmaps.org/xtm/" to identify the XTM namespace. This will usually be near the top of the document. *File extensions(s):* .xtm *Macintosh File Type Code(s):* "xtm " *For further information:* contact the editors, Lars Marius Garshol <larsga@garshol.priv.no> and Graham Moore <graham.moore@networkedplanet.com>, or ISO SC34. More information may be found on the website of ISO SC34 WG3: <http://www.isotopicmaps.org>. *Intended usage:* COMMON *Author/Change controller:* The XTM standard was produced by ISO SC34, which has change control over the standard. --------------------------------------------------------------------- --Lars M. http://www.garshol.priv.no/tmphoto/ http://www.garshol.priv.no/blog/
