XML Shareable Playlist Format (XSPF)

XML Shareable Playlist Format (XSPF), pronounced spiff[1], is an XML-based playlist format for digital media, sponsored by the Xiph.Org Foundation. Lucas Gonze of Yahoo.com/Webjay.org originated the format in 2004.
XSPF is a data format for sharing the kind of playlist that can be played on a personal computer or portable device. In the same way that any user on any computer can open any web page, XSPF is intended to provide portability for playlists.

Features
  • A playlist format like M3U or ASX
  • MIME content-type of application/xspf+xml
  • Patent-free (no patents by the primary authors)
  • Specification under the Creative Commons Attribution-NoDerivs 2.5 license
  • XML, like Atom
  • Unicode support
  • Cross-platform support
    History
    XSPF was created by an ad-hoc working group which kicked off in February 2004, achieved rough consensus on version 0 in April 2004, worked on implementations and fine tuning throughout summer and fall 2004, and declared the tuned version to be version 1 in January 2005.

    XSPF is not yet an Internet standard, and is not a recommendation of any standards body besides Xiph.Org Foundation.

    Content Resolution
    Traditionally playlists have been composed of file paths that pointed to individual titles. This allowed a playlist to be played locally on one machine or shared if the listed file paths were URLs accessible to more than one machine (i.e. on the web). XSPF's meta-data rich open format has permitted a new kind of playlist sharing called content resolution.
    In the simplest terms, content resolution is the local recreation of a playlist based on meta-data. A content resolver will open XSPF playlists and search a catalog for every title with , and Yahoo! Music Unlimited or some other searchable archive. The end result are shareable playlists that are not tied to a specific collection or service.
