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:

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.

   must disclose the information in accordance with [36]section 6 of
