Gonze Expires March 27, 2007 [Page 1] Internet-Draft Media type application/xspf+xml September 2006 Abstract This document defines a new media type for the XML Shareable Playlist Format (XSPF, pronounced like "spiff"). XSPF allows playlists to be exchanged between different software, across networks and across administrative boundaries. A media type registration enhances shareability. An XSPF playlist describes a sequence of objects to be rendered in time. Objects might be audio, video, text, playlists, or any other media type with an inherent duration. The function of an XSPF document is to identify the objects and communicate their order. Table of Contents 1. Requirements notation . . . . . . . . . . . . . . . . . . . . . 3 2.

Requirements notation The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. Gonze Expires March 27, 2007 [Page 3] Internet-Draft Media type application/xspf+xml September 2006 2. Registration Type name: application Subtype name: xspf+xml Required parameters: none Optional parameters: charset. Same as charset parameter of application/xml as specified in [RFC3023]. Encoding considerations: Same as encoding considerations of application/xml as specified in [RFC3023]. Interoperability considerations: Versions 0 and 1 are compatible except for some playlist publication dates which precede the first publication of either specification, hence are impossible in practice. This media type registration encompasses both versions. Published specification: http://xspf.org/xspf-v1 (version 1) http://xspf.org/xspf-v0 (version 0) Applications that use this media type: Gnomoradio, Webjay.org, Musicplayer, Playr, Jinzora, Yahoo Music Engine, Serpentine, Plurn, ultraPh0nZ FMP256, Spiffy, Plext, BMPx, I/ON, Drupal playlist module, Wordpress playlist module, Ning, Music For Dozens, Musicmobs/Mobster, VLC media player, AmaroK, Pear:: Package::File_XSPF, CPAN XML::XSPF, Odeo, Jamendo, ArtistServer, Project Opus, (others) Additional information: Magic number(s): none, but see section 3.1 of [RFC3023]. File extension(s): .xspf Macintosh file type code(s): "TEXT" Fragment/anchor identifiers: see [RFC3023]. Person & email address to contact for further information: Lucas Gonze Gonze Expires March 27, 2007 [Page 4] Internet-Draft Media type application/xspf+xml September 2006 Intended usage: COMMON Restrictions on usage: none Author/change controller: The XSPF specification is a work product of the Xiph.org Foundation's Playlist Ad Hoc Group. The working group's home on the web is http://xspf.org. The specifications were edited by Lucas Gonze , Matthias Friedrich , and Robert Kaye . XML namespace: http://xspf.org/ns/0 Base URIs: see [RFC3023]. BOM: see [RFC3023]. Gonze Expires March 27, 2007 [Page 5] Internet-Draft Media type application/xspf+xml September 2006 3. Security considerations The XML-based media type being registered has all of the security considerations described in [RFC3023] plus additional considerations. Playlist authors who publish documents containing local filesystem paths should take care to not reveal confidential information contained in those strings. The registration does not employ active content. Gonze Expires March 27, 2007 [Page 6] Internet-Draft Media type application/xspf+xml September 2006 4.
