SMIL Animation

This is a W3C Recommendation of a specification of animation functionality for XML documents. It describes an animation framework as well as a set of base XML animation elements suitable for integration with XML documents. It is based upon the SMIL 1.0 timing model, with some extensions, and is a true subset of SMIL 2.0. This provides an intermediate stepping stone in terms of implementation complexity, for applications that wish to have SMIL-compatible animation but do not need or want time containers.

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 document 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.

The SMIL Animation specification has been produced as part of the W3C Synchronized Multimedia Activity and was written by the SYMM Working Group (members only) of the W3C Interaction Domain, working with the SVG Working Group (members only) of the W3C Document Formats 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).

The SYMM Working Group (members only) considers that all features in the SMIL 2.0 specification have been implemented at least twice in an interoperable way. The SYMM Working Group Charter (members only) defines this as the implementations having been developed independently by different organizations and each test in the SMIL 2.0 test suite has at least two passing implementations. The 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 specification (and thus with the SMIL Animation specification also), these may be found on the SYMM Patent Statement page in conformance with W3C policy.
