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.

1.  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] (Bradner, S., “Key words for use in RFCs to Indicate Requirement Levels,” March 1997.).

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] (Murata, M., St. Laurent, S., and D. Kohn, “XML Media Types,” January 2001.).

Encoding considerations:

Same as encoding considerations of application/xml as specified in [RFC3023] (Murata, M., St. Laurent, S., and D. Kohn, “XML Media Types,” January 2001.).

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] (Murata, M., St. Laurent, S., and D. Kohn, “XML Media Types,” January 2001.).

File extension(s):

.xspf

Macintosh file type code(s):

"TEXT"

Fragment/anchor identifiers:

see [RFC3023] (Murata, M., St. Laurent, S., and D. Kohn, “XML Media Types,” January 2001.).

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 <[email protected]>, Matthias Friedrich <[email protected]>, and Robert Kaye <[email protected]>.

XML namespace:

http://xspf.org/ns/0

Base URIs:

see [RFC3023] (Murata, M., St. Laurent, S., and D. Kohn, “XML Media Types,” January 2001.).

BOM:

see [RFC3023] (Murata, M., St. Laurent, S., and D. Kohn, “XML Media Types,” January 2001.).

3.  Security considerations

The XML-based media type being registered has all of the security considerations described in [RFC3023] (Murata, M., St. Laurent, S., and D. Kohn, “XML Media Types,” January 2001.) 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.
