Review requested for MusicXML media type proposals
by Michael Good 10 Jul '07

10 Jul '07

MusicXML is a digital sheet music format currently used for interchange between Finale, Sibelius, and over 75 other music notation programs. The format was developed by Recordare LLC and you can find more information at Recordare's web site: http://www.recordare.com/xml.html The current version is 1.1, but version 2.0 is in beta test. The main goal of the MusicXML 2.0 update is to move from being primarily a music notation interchange format to being a music notation distribution format - the equivalent of MP3 files for digital sheet music. With this broader goal, it now seems appropriate to register media types. MusicXML 2.0 files will come in two versions: an uncompressed XML file similar to what is used in the current MusicXML format, and a zip-compressed XML file similar to what is used in ODF and other XML-based distribution formats. We are proposing two media types for these two versions: application/vnd.recordare.musicxml application/vnd.recordare.musicxml+xml The +xml version is for the uncompressed XML file; the other is for the compressed file format. We have posted draft registration proposals on the MusicXML developer mailing list and are now ready for review on this list. My next two e-mail messages will be the registration proposals for these two media types. Thank you very much for your assistance in reviewing these proposals.

MIME type for diffs, *any* MIME type
by Lisa Dusseault 27 Jun '07

27 Jun '07

Hi, This has come up before and stalled the whole attempt to standardize a PATCH method for HTTP: the lack of a properly registered MIME type for any binary or text diff format. The GDiff format described in http://www.w3.org/TR/NOTE- gdiff-19970901 states the MIME type but it was never registered. The IPR situation is completely unclear. No author of this has ever responded to my pings. The VCDIFF format is described in http://www.faqs.org/rfcs/ rfc3284.html does not choose a MIME type. The IPR disclosure <https:// datatracker.ietf.org/public/ipr_detail_show.cgi?ipr_id=40> states that AT&T grants licenses to "transmit data over the Internet under HTTP 1.1". I do not want to start to interpret whether that covers new HTTP 1.1 methods as well as the ones that existed when this grant was made. An AT&T guy responded to my emails and said he'd suggest a more liberal license to the lawyers but we never saw anything come of that. Julian recently mentioned the POSIX 'diff' format which is most widely used and probably under the most liberal license due to existing source code licenses. No official MIME type was ever suggested for this until Julian's mail but a bit of googling suggests that some applications informally use application/diff and this is probably what is meant by that. I am unaware of an existing formal spec for this -- and that's the sticking point for registering this one -- although clearly interoperability is common. Can we just ask IANA to register any or all of these, perhaps with appropriate disclaimers in the form about IPR or specification formality? Surely that would be better than the status quo. Can I help cut red tape here? Lisa

review of media type and URI from draft-levin-mmusic-xml-media-control-10.txt
by Even, Roni 19 Jun '07

19 Jun '07

Hi, I would like to ask for review of a media type and new URI for an XML namespace defined in http://tools.ietf.org/wg/mmusic/draft-levin-mmusic-xml-media-control-10.txt. The text from the draft is listed here. 1. Application/media_control+xml media type registration Media Type Name: application subtype name: media_control+xml Required parameters: None Optional parameters: charset See RFC 3023 [4] for a discussion of the charset parameter on XML- derived types. Since this type is used exclusively in SIP, the use of UTF-8 encoding is strongly encouraged. Encoding considerations: 8-bit text Security considerations: Security considerations specific to uses of this type are discussed in RFC xxxx [[Note to RFC editor: replace xxxx with the RFC number of this document when published]]. RFC 1874 [1] and RFC 3023 [4] discuss security issues common to all uses of XML. Interoperability considerations: The use of this media type body is intended to be generally interoperable. No unique considerations have been identified. Published specification: RFC xxxx [[Note to RFC editor: replace xxxx with the RFC number of this document when published]] Applications which use this media type: This media type is used to convey information regarding media control commands and responses between SIP endpoints particularly for allowing a Video Fast Update intra-frame request. Additional information: Magic Number(s): None. File Extension(s): None. Macintosh File Type Code(s): None. Object Identifier(s) or OID(s): None. Intended usage: Limited Use Person to contact for further information: Name: Orit Levin E-Mail: oritl(a)microsoft.com Other Information/General Comment: None. Author/Change Controller: Orit Levin. 2. URN for XML schema URI: urn:ietf:params:xml:ns:media_control Description: This is the XML namespace URI for XML elements defined by [RFCXXXX] to describe information exchanged between SIP endpoints for media control. It is used in the application/media_control+xml body type. Registrant Contact: Name: Orit Levin E-Mail: oritl(a)microsoft.com Author/Change Controller: Orit Levin. XML: BEGIN <?xml version="1.0"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML Basic 1.0//EN" "http://www.w3.org/TR/xhtml-basic/xhtml-basic10.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="content-type" content="text/html;charset=utf-8"/> <title>Namespace for Tight Media Control</title> </head> <body> <h1>Namespace for Tight Media Control</h1> <h2>application/media_control+xml</h2> <p>See <a href="[[[URL of published RFC]]]">RFCXXXX</a>.</p> </body> </html> END Thanks Roni Even

Media type for output of POSIX "diff" utility
by Julian Reschke 04 Jun '07

04 Jun '07

Hi, I think it would be good to have a specific media type for the output of the POSIX "diff" tool (see <http://www.opengroup.org/onlinepubs/000095399/utilities/diff.html>). Questions: - Am I missing something (meaning, is there already one)? - Were there previous attempts to to this that failed? (why?) - Would the specification at <http://www.opengroup.org/onlinepubs/000095399/utilities/diff.html> be sufficient as specification of the contents of the file? - Would it make sense to define individual types for the different diff output formats (simple, context, ...), or would that be something for a type parameter? Feedback appreciated, Julian
