## 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. The latest status of this document series is maintained at the W3C.

This is a W3C Working Draft of the Synchronized Multimedia Integration Language (SMIL) 2.0 specification produced by the SYMM Working Group [members only]. This specification is a revision of the W3C Last Call Working Draft 21 September 2000, incorporating comments and suggestions received during the Last Call review. Only minor editing updates are expected in the upcoming Candidate Recommendation version.

The XHTML+SMIL Profile which appeared in previous working drafts is still in progress and not yet ready for Last Call. It continues to be updated and will be published as a separate Working Draft when it is ready. Refer to the available public working draft version of that profile.

This is a W3C Working Draft for review by W3C Members and other interested parties. It is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to use W3C Working Drafts as reference material or to cite them as other than "work in progress". This is work in progress and does not imply endorsement by, or the consensus of, the W3C Membership.

This document has been produced as part of the W3C Synchronized Multimedia Activity of the W3C User Interface Domain. The goals of the SYMM Working Group are discussed in the SYMM Working Group charter [members only], (revised July 2000 from original charter version).
