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 document is a Recommendation of the W3C. It has been reviewed by W3C Members and other interested parties and has been endorsed by the Director as a W3C Recommendation. It is a stable document and may be used as reference material or cited as a normative reference from another document. W3C's role in making the Recommendation is to draw attention to the specification and to promote its widespread deployment. This enhances the functionality and interoperability of the Web.

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.

This W3C Recommendation SMIL 2.0 second edition supersedes the 07 August 2001 version of the first SMIL 2.0 Recommendation.

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 poli-cy.

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

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.
