Abstract

This document specifies the third version of the Synchronized Multimedia Integration Language (SMIL, pronounced "smile"). SMIL 3.0 has the following design goals:

• Define an XML-based language that allows authors to write interactive multimedia presentations. Using SMIL, an author may describe the temporal behaviour 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 components are used for integrating timing into XHTML [XHTML10] and into SVG [SVG].
• Extend the functionalities contained in the SMIL 2.1 [SMIL21] into new or revised SMIL 3.0 modules.
• Define new SMIL 3.0 Profiles incorporating features useful within the industry.

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 Recommendation (PR) of the Synchronized Multimedia Integration Language (SMIL) 3.0.
This document is based upon the SMIL 3.0 Candidate Recommendation published on 15 January 2008. The current document contains editorial improvements, and minor bug fixes. The significant changes in this draft are available in the changeslog.

W3C Advisory Committee Members are invited to send formal review comments to the W3C Team until 06 November 2008. Review comments should be sent to symm-review@w3.org; comments sent there will be made available to members after the review period ends. People wanting their comments visible to members sooner, or to be archived publicly, can send a cc to the ac-forum@w3.org list or to www-archive@w3.org as appropriate. The public is invited to send comments to the public mailing list www-smil@w3.org [archives], including the prefix'[SMIL30 PR]' in the subject line.
After the review the Director will announce the document's disposition. This announcement should be expected no sooner than 14 days after the end of the review.

Feedback received during that review resulted in clarifications but no major changes. The SYMM Working Group believes that this specification addresses all Candidate Recommendation issues. Evidence of interoperability between at least two implementations of this specification are documented in the Implementation Report.

The SMIL 3.0 test suite along with an implementation report are publicly released and are intended solely to be used as proof of SMIL 3.0 implementability. It is only a snapshot 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.

This document has been produced by the SYMM Working Group as part of the W3C Synchronized Multimedia Activity, following the procedures set out for the W3C Process. The goals of the SYMM Working Group are discussed in the SYMM Working Group Charter. The authors of this document are the SYMM Working Group members. Different parts of the document have different editors.

This document was produced by a group operating under the 5 February 2004 W3C Patent Policy. W3C maintains a public list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent. An individual who has actual knowledge of a patent which the individual believes contains Essential Claim(s) must disclose the information in accordance with section 6 of the W3C Patent Policy.

Publication as a Proposed 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.
