'''XML Shareable Playlist Format''' ('''XSPF'''), pronounced ''spiff'',<ref>{{cite web |url=http://xspf.org/quickstart/|title=XSPF: XML Shareable Playlist Format: Quick Start|accessdate=2009-04-23}}</ref> is an [[XML]]-based [[playlist]] format for [[digital media]], sponsored by the [[Xiph.Org Foundation]].

XSPF is a datafile 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 webWeb 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 webWeb). 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 <tt>&lt;creator&gt;</tt>, <tt>&lt;album&gt;</tt> and <tt>&lt;title&gt;</tt> 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.

== History ==

XSPF was created by an ''ad hoc'' working group whichthat kickedcommenced offactivities 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.
