This page summarizes the relationships among specifications, whether they are finished standards or drafts. Below, each title links to the most recent version of a document.
W3C Recommendations have been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and are endorsed by the Director as Web Standards. Learn more about the W3C Recommendation Track.
Group Notes are not standards and do not have the same level of W3C endorsement.
This document specifies the distribution format exchange profile (DFXP) of the timed text authoring format (TT AF) in terms of a vocabulary and semantics thereof.
The timed text authoring format is a content type that represents timed text media for the purpose of interchange among authoring systems. Timed text is textual information that is intrinsically or extrinsically associated with timing information.
The Distribution Format Exchange Profile is intended to be used for the purpose of transcoding or exchanging timed text information among legacy distribution content formats presently in use for subtitling and captioning functions.
In addition to being used for interchange among legacy distribution content formats, DFXP content may be used directly as a distribution format, for example, providing a standard content format to reference from a
This document specifies the third version of the Synchronized Multimedia Integration Language (SMIL, pronounced "smile"). SMIL 3.0 has the following design goals:
This document specifies the second version of the Synchronized Multimedia Integration Language (SMIL, pronounced "smile"). SMIL 2.1 has the following design goals:
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 specification defines an XML timing language that makes SMIL 3.0 element and attribute timing control available to a wide range of other XML languages. This language allows SMIL timing to be integrated into a wide variety of a-temporal languages, even when several such languages are combined in a compound document. Because of its similarity with external style and positioning descriptions in the Cascading Style Sheet (CSS) language, this functionality has been termed SMIL Timesheets.
This document specifies usage scenarios and requirements for a timed text authoring format. A timed text authoring format is a content type that represents timed text media for the purpose of interchange among authoring systems. Timed text is textual information that is intrinsically or extrinsically associated with timing information.
The XHTML+SMIL profile defines a set of XHTML abstract modules that support a subset of the SMIL 2.0 specification.
These specifications have either been superseded by others, or have been abandoned. They remain available for archival purposes, but are not intended to be used.
