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 https://www.w3.org/TR/.
This document has been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and is endorsed by the Director as a W3C Recommendation. It is a stable document and may be used as reference material or cited 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 SMIL 3.0 edition is a new version, it extends the functionalities contained in SMIL 2.1 [SMIL21], incorporating new features useful within the industry.
This SMIL3.0 W3C Recommendation supersedes the 13 December 2005 SMIL 21 Recommendation [SMIL21].
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.
