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.

Completed Work
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.

SMIL 3.0 Recommendation specifies the third version of the SMIL. It
is built on top of SMIL 2.1. It extends the functionalities contained
in SMIL 2.1 into new or revised SMIL 3.0 modules. It also defines new
SMIL 3.0 Profiles incorporating features useful within the industry.

SMIL 2.1 Recommendation specifies the second version of the
Synchronized Multimedia Integration Language (SMIL, pronounced
"smile"). SMIL 2.1 has the following design goals:
* Define an XML-based language that allows authors to write
interactive multimedia presentations. Using SMIL, an author can
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.
* Extend the functionalities contained in the SMIL 2.0 [SMIL20] into
new or revised SMIL 2.1 modules.
* Define new SMIL 2.1 Mobile Profiles incorporating features useful
within the mobile industry..

SMIL Animation Recommendation specifies 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..

SMIL 1.0 Recommendation specifies the first version of SMIL to allow
integrating a set of independent multimedia objects into a synchronized
multimedia presentation. Using SMIL, an author can describe the
temporal behavior of the presentation, describe the layout of the
presentation on a screen and associate hyperlinks with media objects

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 Note describes 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..

This Note describes a snapshot of certain aspects of the discussions
on future work on SYMM and SMIL. Following the approach spearheaded by
the W3C HTML Working group, the Note describes how SMIL 1.0
functionality and future SYMM functionality can be represented as a set
of markup modules. The intention was to study the feasibility of such
an approach, and the details of the proposed modularisation are
preliminary only.

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
<text> or <textstream> media object
element in a [SMIL 2.1] document.
