XSPF is a file 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.

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 (e.g., on the Web). XSPF's meta-data rich open format has permitted a new kind of playlist sharing called content resolution.

A simple form of content resolution is the localisation of a playlist based on metadata. An XSPF-compliant content resolver will open XSPF playlists and search a catalog for every title with <creator>, <album> and <title> tags, then localise the playlist to reference the available matching tracks. A catalog may reference a collection of media files on a local disk, a music subscription service like Yahoo! Music Unlimited, or some other searchable archive. The end result is shareable playlists that are not tied to a specific collection or service.

Example of an XSPF 1.0 playlist

 
<?xml version="1.0" encoding="UTF-8"?>
<playlist version="1" xmlns="http://xspf.org/ns/0/">
  <trackList>
    <track>
      <title>Windows Path</title>
      <location>file:///C:/music/foo.mp3</location>
    </track>
    <track>
      <title>Linux Path</title>
      <location>file:///media/music/foo.mp3</location>
    </track>
    <track>
      <title>Relative Path</title>
      <location>music/foo.mp3</location>
    </track>
    <track>
      <title>External Example</title>
      <location>http://www.example.com/music/bar.ogg</location>
    </track>
  </trackList>
</playlist>

History

XSPF was created by an ad hoc working group that commenced activities 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 a recommendation of any standards body besides the Xiph.Org Foundation.

Features

Software and web playlist converters
gollark: Apparently they just... got it wrong in this case? Weird.
gollark: Not really. Most sanely configured stuff ignores x-forwarded-for and whatnot from clients.
gollark: I looked up the extension in question though, and it does sort of make sense what it does.
gollark: It wouldn't be a HTTP header, that's the wrong layer.
gollark: Oh, I see, it pretends to be a reverse proxy and some poorly configured thing accepts it.
