Abstract

This document specifies the second version of the Synchronized Multimedia Integration Language (SMIL, pronounced "smile"). SMIL 2.0 has the following two design goals:

• Define an XML-based language that allows authors to write interactive multimedia presentations. Using SMIL 2.0, an author can describe the temporal behavior of a multimedia presentation, associate hyperlinks with media objects and describe the layout of the presentation on a screen.
• Allow reusing of SMIL syntax and semantics in other XML-based languages, in particular those who need to represent timing and synchronization. For example, SMIL 2.0 components are used for integrating timing into XHTML [XHTML10] and into SVG [SVG].

Status of this document

This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http://www.w3.org/TR/.

This is a W3C Proposed Edited Recommendation, a revised edition of the Synchronized Multimedia Integration Language (SMIL) 2.0.
It is here made available for review by W3C members and other interested parties. Note that a Candidate Recommendation draft has not been deemed necessary by the Working Group, as there are no substantial implementation issues arising as a result of this edition, which aims only to incorporate the published corrigenda to the first edition.
If this document is approved as a W3C Recommendation, it will supersede the 07 August 2001 version of the the SMIL 2.0 Recommendation.

Please send comments on this Proposed Edited Recommendation to www-smil@w3.org, including 2E PER in the subject line, no later than 05 December 2004.
Publication as a Proposed Edited Recommendation does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.

This document has been produced by the SYMM Working Group [members only] as part of the W3C Synchronized Multimedia Activity. The goals of the SYMM Working Group are discussed in the SYMM Working Group charter [members only].

This second edition of SMIL 2.0 is not a new version, it merely incorporates the changes dictated by the corrections to errors found in the first edition as agreed by the SYMM Working Group, as a convenience to readers. A separate list of all such corrections is available at http://www.w3.org/2001/07/REC-SMIL20-20010731-errata.
The errata list for this second edition is available at http://www.w3.org/2004/06/EditedREC-SMIL20-errata.

The SMIL 2.0 test suite and Implementation results are publicly released and are intended solely to be used as proof of SMIL 2.0 implementability. It is only a snap shot of the actual implementation behaviors at one moment of time, as these implementations may not be immediately available to the public. The interoperability data is not intended to be used for assessing or grading the performance of any individual implementation.

There are patent disclosures and license commitments associated with the SMIL 2.0 Recommendation, these may be found at the Working Group's public SYMM Patent Statement page in conformance with W3C policy.

The 7 August 2001 version of the SMIL 2.0 Recommendation was published before W3C adopted a specific Patent Policy. Per the Patent Policy Transition Procedure, this revision of the Recommendation will therefore be covered by the 24 January 2002 Current Patent Practice.

Please report errors in this document to www-smil@w3.org - (public archives).

The authors of this document are the SYMM Working Group members. Different parts of the document have different editors.
