I am pleased to announce the advancement of "Timed Text (TT) Authoring
Format 1.0 Distribution Format Exchange Profile (DFXP)" to Candidate
Recommendation:
http://www.w3.org/TR/2006/CR-ttaf1-dfxp-20061116/
The disposition of Last Call comments is available at:
http://www.w3.org/2005/03/21/DFXP-2ND-LastCallResponses
There were no new formal objections during the second Last Call. During the
first Last Call (all comments [1]), there were comments [2] that the Working
Group was unable to resolve to the satisfaction of the commenter(s). The
status of these comments and the Working Group's responses [3] has not
changed. See the first Last Call Disposition of Comments for full
discussion:
http://www.w3.org/2005/03/21/DFXPLastCallResponses#Issue11
A preliminary DFXP 1.0 test suite is available at:
http://www.w3.org/2006/DFXP/testsuite/
A preliminary implementation report is available at:
http://www.w3.org/2006/DFXP/DFXP-implementation-result
There are no patent disclosures relevant to this specification; please see
the Timed Text Working Group's patent disclosure page:
http://www.w3.org/2003/01/Timed-text-Patent-statements
The Timed Text Working Group expects to receive more comments in the form of
implementation feedback and test cases. The Working Group believes it will
have satisfied its implementation criteria by 16 February 2007.
This Call for Implementations follows section 7.4.3 of the W3C Process

Abstract
--------
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.
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 http://www.w3.org/TR/.
This is the 10 November 2006 Candidate Recommendation of the Timed
Text (TT) Authoring Format 1.0 Distribution Format Exchange
Profile (DFXP). W3C publishes a Candidate Recommendation to indicate
that the document is believed to be stable and to encourage
implementation by the developer community. The [15]Timed Text (TT)
Working Group expects to request that the Director advance this
document to Proposed Recommendation once the Working Group has, for
each test in the [16]DFXP 1.0 Test Suite, demonstrated support by
two interoperable implementations. The Working Group, working
closely with the developer community, expects to show these
implementations by 16 February 2007. This estimate is based in part
on the preliminary [17]DFXP Interoperability Implementation Report.
The Working Group does not plan to request to advance to Proposed
Recommendation prior to 16 January 2007.

This is a W3C Candidate Recommendation. The second Last Call Working
Draft for this specification resulted in a number of Last Call
comments which have all been addressed by the working group; a list
of all Last Call comments can be found in the [18]Second Last Call
Comments List. The list of changes made since the last public
Working Draft is available in [19]M.2 Changes from Second Last Call
Working Draft to Candidate Recommendation.

During the first Last Call period of this specification, there were
[20]unsatisfied comments that the working group was unable to
resolve in a manner that satisfied the commenter(s). The status of
these comments has not changed during the second Last Call period,
as the working group continues to stand by its [21]original
responses. See also the [22]First Last Call Disposition of Comments
for a complete discussion.

The dynamic flow processing feature, as specified by the
[23]tts:dynamicFlow styling attribute vocabulary, see also [24]B
Dynamic Flow Processing Model, has been determined to be [25]at
risk, and is expected to be given the greatest scrutiny in the
implementation report.

This document is governed by the [32]24 January 2002 CPP as amended
by the [33]W3C Patent Policy Transition Procedure. W3C maintains a
[34]public list of any patent disclosures made in connection with
the deliverables of the group; that page also includes instructions
for disclosing a patent. An individual who has actual knowledge of a
patent which the individual believes contains [35]Essential Claim(s)
must disclose the information in accordance with [36]section 6 of
the W3C Patent Policy.
