+This directory contains source files for creating the version 1 flavor of the XSPF spec.
+
+The important files are rfc2629.xslt and xspf2629.xml. These files
+are combined to make an HTML version of the spec as follows:
+
+xsltproc rfc2629.xslt xspf2629.xml > xspf-v1.html
+
+rfc2629.xslt is a modified version of Julian F. Reschke's XSLT
+transformation from RFC2629 XML format to HTML. The original,
+unmodified, version is in rfc2629.xslt-orig.
+
+xspf2629.xml is source for the XSPF spec, formatted per RFC 2629.
+Note that Julian's XSLT does not support all features of RFC 2629, and
+also that I have slightly modified Julian's XSLT to support new
+features, so xspf2629.xml is tightly coupled with the XSLT file here.
+
+The specification source document, HTML document, and modifications to
+rfc2629.xslt are the work of Lucas Gonze <lucas at gonze.com>.

+ standards of the formats for web pages (HTML), weblogs (RSS),
+ and web graphs (RDF/XML). It is evident that there is a need,
+ because XML is the preferred data description language of the
+ moment and as a result the tools and skills to use it are
+ ubiquitous.</t>
+
+ <t>It is also evident that existing playlist formats fall short.
+ ASX (for Windows Media Player) and the iTunes library format
+ are proprietary. ASX resembles XML in that it uses angle
+ brackets, but is not XML by any means. M3U, RAM, and M4U are
+ flat files; QuickTime is binary; Pls is in the Windows .ini
+ format; Gnomoradio RDF is RDF, not XML. SMIL addresses a much
+ larger problem space than the average MP3 player. The timing
+ model of RSS doesn't fit audio and video. Forcing timing
+ models into HTML, as HTML+Time does, creates an unintelligible
+ feature set. Few of these formats are well documented. None
+ of these formats make simple features easy to code and hard
+ features possible. Only one is an open standard. Not one
+ offers playlist interoperability across major vendors.</t>
+
+ <t>The question for software developers is <spanx
+ style="emph">why should I support this new XML playlist
+ format</spanx>? The choice is mainly between M3U and SMIL.
+ Almost every MP3 player accepts M3U but also invents an XML
+ playlist format. Inventing a format creates work, for
+ example to study related formats; you should use XSPF to
+ avoid the work. SMIL, on the other hand, is a prescription
+ for a kind of application that is different from an MP3
+ player -- it describes layouts in time, while XSPF describes
+ concepts common among MP3 players. Given a song with the
+ comment "danceable!", SMIL might have an instruction to
+ write that text in the upper left in a bold sans-serif font,
+ while XSPF would tell an MP3 player that the text is a
+ comment and say nothing about formatting.</t>

+
+ <t>Our group started work in February 2004, achieved rough
+ consensus on version 0 in April 2004, did implementations
+ and fine tuning throughout summer and fall 2004, and
+ declared the tuned version to be version 1 in January
+ 2005. Version 1 is not far from being frozen and
+ code-ready.</t>
+
+ <t>This document describes version 1, which is not ready for
+ implementation. Version 0, the previous one, is stable and

+ <t>The terms URI, URL, and URN should be interpreted here as

+ may be purely an abstraction; a URI is either. In this

+ //playlist/trackList/track/identifier are URNs, all other
+ elements are URLs.</t>

+ <section title="Abstractions">
+
+ <section title="Defining playlists">
+
+ <t>An XSPF playlist describes a sequence of objects to
+ be rendered. Objects might be audio, video, text,
+ playlists, or any other media type. The function of a
+ playlist is to identify the objects and communicate
+ their order.</t>
+ </section>
+
+ <section title="What a playlist is not">
+
+ <t>The function of a playlist <spanx style="emph">is not</spanx> to
+ communicate metadata about the composer, song title,
+ etc. Metadata is hard and there are many providers
+ already. We decided that we couldn't compete, and
+ that there was no need for us to try. Moreover, good
+ metadata does not travel well -- every user has to
+ recreate it. Metadata should come from external
+ sources and namespaces like MusicBrainz or Gracenote;
+ this what the XSPF <spanx class="verb">link</spanx>
+ and <spanx class="verb">meta</spanx> elements are
+ for.</t>
+
+ <t>The function of a playlist <spanx style="emph">is not</spanx> to store
+ derived information about objects that a user has a
+ copy of. A playlist is not a catalog. A catalog is
+ computed across hard data like files; it stores
+ information like filesystem paths and the contents of
+ ID3 tags. This data has no value on any machine but
+ the one on which it originated. Sharing this data
+ would be a privacy and security violation. Software
+ which needs access to this data has no reason to
+ maintain it in a standard format, because it has no
+ reason to allow access to it. Standardizing this data
+ would be fruitless, because there are an endless
+ number of measurements that software might take and
+ store. Derived information belongs in
+ a <spanx style="emph">catalog</spanx>.</t>
+
+ <t>Things a playlist is not, then, are a metadata format or a
+ catalog. We took care to enable these features, but also to
+ avoid duplicating their functionality, poorly.</t>
+
+ </section>
+
+ <section title="Shareability">
+ <t>If there is no reason for a playlist to be shared, there is
+ no need for a new format. Even a buggy format does no
+ damage if it is created and consumed by the same software on
+ the same machine. The need for a new format only comes up
+ when a playlist travels from one machine to another, for
+ example when it is published on the internet.</t>
+
+ <t>One type of shareability is between different pieces of
+ software on the same machine. It is common for playlists
+ created with one application to not be usable by another
+ application on the same machine because of different or
+ conflicting interpretations of the playlist format. M3U
+ suffers from this very badly, because M3U playlists often
+ reference files according to a base path which changes from
+ application to application. The XSPF group aimed to fix this
+ by providing unambiguous definitions.</t>
+
+ <t>The other type of shareability is between different
+ machines. For playlists to be meaningful on different
+ machines, they must be able to identify network resources.
+ Audio and video objects are often abstractions like "movie X
+ by director Y" rather than computer-friendly objects like
+ "whatever file can be gotten from the URL http://foo/x/y". To
+ handle this problem, we have provided support for media
+ objects to be found via queries; XSPF identifiers
+ are <spanx style="emph">fuzzy names</spanx>.</t>
+ </section>
+
+ <section title="Content resolver">
+
+ <t>On a surface level you can use XSPF like any other playlist
+ format. Drop a bunch of filenames into an XSPF document, prepend
+ "file://" to each, and you're ready to go. Under the surface
+ there is much more.</t>
+
+ <t>The guiding design principle was to separate the functionality
+ of a catalog of files from the functionality of a list of songs.
+ Most MP3 players have some sort of cache for file information.
+ This cache stores a list, or catalog, of available files and
+ metadata from ID3 tags and other sources. XSPF is not a catalog
+ format. XSPF exists only to say which songs to play. Almost
+ everything in XSPF is for the purpose of answering the
+ question <spanx class="emph">which resource</spanx>, rather than the
+ question <spanx class="emph">what is this resource</spanx>.</t>
+
+ <t>If XSPF is not a catalog format, what is it? XSPF is an
+ intermediate format. We expected a new kind of software called
+ a <spanx class="emph">content resolver</spanx> to do the job of converting XSPF to a
+ plain old list of files or URLs. A content resolver would be
+ smart enough to keep your playlists from breaking when you move
+ your MP3s from /mp3s to /music/mp3. It would be able to figure
+ out that a playlist entry by the artist "Hank Williams" with the
+ title "Your Cheating Heart" could be satisfied by the file
+ /mp3s/hankwilliams/yourcheatingheart.mp3. It might even know how
+ to query the iTunes music store or another online provider to
+ locate and download a missing song.</t>
+
+ <t>The content resolver maintains the catalog of your songs in
+ whatever format it prefers. It might use a flatfile, a file in
+ the Berkeley DB format, or a SQL database. It might use only ID3
+ metadata, but it might also know how to query MusicBrainz or
+ another metadata service.</t>
+ </section>
+
+ <section title="Fuzzy names">
+ <t>Any given track can be identified in a number of ways. We
+ provided means for absolute identifiers like URLs, filesystem
+ paths and secure hashes, but also for query-based identifiers --
+ free text fields like artist and work title and numeric fields
+ for song length, all of which together should be enough for a
+ good content resolver to turn into files.</t>

+ Before handing off control to the helper application,
+ the browser must download whatever the link points to.
+ For streaming media this makes no sense; either the
+ download will never finish or waiting for a complete
+ download defeats the purpose.</t>
+
+ <t>Typical solution: rather than linking to an audio
+ or video document, link to a playlist containing a URL
+ of an audio or video document. Playlists used for
+ this purpose often contain only a single URL. The Pls
+ format, which is used for MP3-based webcasting, and
+ which contains a single URL of a never-ending stream,
+ takes this approach.</t>
+
+ <t>XSPF' solution: any reasonably compact playlist
+ format supports this equally well. This rules out
+ iTunes library format and sometimes QuickTime, but
+ allows XSPF along with M3U, Pls and other relatively
+ terse formats.</t>

+
+ <section title="Collecting fragmented resources"><!-- first child of usecases -->
+
+ <t>Scenario: There is a very large object like a DVD
+ rip. The likelyhood of downloading the entire object
+ in one shot is low, so the object has been split into
+ pieces. The object then needs to be reassembled on
+ the client side.</t>
+
+ <t>Typical solution: Create a zip file or tarball,
+ which use checksums to ensure integrity of the
+ download; start by sending a playlist which acts a
+ file manifest and allows a user agent to download
+ sub-objects in digestible chunks. However, a manifest
+ has to express paths to related objects according to a
+ filesystem which does not exist on the client, there
+ has to be agreement between the client and server on
+ how to interpret relative paths in a playlist. The
+ problem is that few playlist formats -- only SMIL, to
+ my knowledge -- define the meaning of relative paths
+ in a playlist.</t>
+
+ <t>XSPF' solution: XSPF clearly defines the meaning of
+ relative paths according to the rule that a client
+ must interpret relative paths in a playlist according
+ to the XML Base specification or IETF RFC 2396.</t>
+
+ </section>
+
+ <section title="Alternate media types"><!-- first child of usecases -->
+ <t>Scenario: There is a renderer which is capable of
+ rendering one form of a media object but not another.
+ The server is able to deliver the object in either
+ format, but it needs to communicate URLs for both.
+ Though HTTP content negotiation can be used for
+ instances where the renderer contacts the server
+ directly, it doesn't support protocol negotiation, and
+ it can't be used in non-HTTP protocols.</t>
+
+ <t>Typical solution: This is particularly a problem
+ for Real, which has a large installed base of obsolete
+ software to be babied. The solution is to delver
+ alternate URLs within the same playlist and allow the
+ client to choose. The RAM format allows both a pnm:
+ and a rtsp: URL within the same playlist, separated by
+ a line containg the keyword "--stop--".</t>
+
+ <t>XSPF' solution: An XSPF track object can contain
+ multiple identifiers or locations for the same media
+ object.</t>
+ </section>
+
+ <section title="Caching derived info"><!-- first child of usecases -->
+
+ <t>Scenario: An MP3 player needs to access information
+ about media objects which is too expensive to compute
+ in real time. For a large number of file a user can't
+ wait to re-read ID3 tags, computing SHA1 hashes, or
+ perform a fourier transform for each.</t>
+ <t>Typical solution: An MP3 player computes the
+ information once, the first time it encounters an
+ object, then caches the data. The iTunes library
+ format stores computed information like ID3 data in
+ the global catalog and playlist.</t>
+ <t>XSPF' solution: XSPF defers this information to an
+ external module called the content resolver, and
+ mandates that the information not be included in
+ shared playlists.</t>
+ </section>
+
+ <section title="Metadata storage"><!-- first child of usecases -->
+
+ <t>Scenario: A user needs information about high level
+ concepts like artist and song title rather than
+ machine-level concepts like file name and bit rate.
+ How should artist and song title be communicated, and
+ how should they be stored?</t>
+ <t>Typical solution: Derive the metadata according to
+ an application-defined process like extracting ID3
+ tags, then then store a copy of the metadata in any
+ playlists that reference a media object. The EXTINF
+ property of the extended M3U format is used in this
+ way.</t>
+ <t>XSPF' solution: XSPF defers this functionality to other
+ sources. Metadata is hard; there are already many
+ projects to deal with it, some of which are very good.
+ Metadata is attached to an XSPF track according to
+ whatever syntax an imported vocabulary defines. XML
+ namespaces may be used, but the preferred syntax is the
+ XSPF <spanx class="verb">link</spanx> and <spanx
+ class="verb">meta</spanx> elements. (These elements
+ allows us to validate metadata from external sources,
+ while namespaces don't.)</t>
+ </section>
+
+ <section title="Authoring compilations for expressive reasons"><!-- first child of usecases -->
+
+ <t>Scenario: A businessperson wants to make a batch of
+ videos of related talks from a conference because
+ watching them in a shared context gives a deeper
+ understanding of the subject as a whole.</t>
+
+ <t>Typical solution: A user compiles copies of the
+ videos and puts them in the same location, maybe in
+ the same directory on a web server, maybe in the same
+ directory on a hard drive. The user then puts the
+ locations, whether paths or URLs, into a file in the
+ M3U format.</t>
+
+ <t>XSPF' solution: The XSPF <spanx class="verb">trackList</spanx> element contains a
+ sequence of <spanx class="verb">track</spanx> elements,
+ each of which points to one of the objects.</t>

+ <section title="How do I use MusicBrainz metadata?">
+ <t>
+ Rather than include the literal artist name, song

+ what a track listing means is at
+ http://musicbrainz.org/track. (There is nothing at that
+ URL, which is fine -- the URL in an XSPF meta[@rel]
+ attribute works the same way as the URL in an XML
