Dear Advisory Committee Representative,
Chairs,

I am pleased to announce that Timed Text Markup Language 2 (TTML2) is a W3C Candidate Recommendation (second CR version - CR2):
  https://www.w3.org/TR/2018/CR-ttml2-20180628/

The approval and publication are in response to this transition request:
  https://lists.w3.org/Archives/Member/chairs/2018AprJun/0118.html


Please provide feedback by 26 July 2018 as follows:
Raise an issue in the GitHub repository <https://github.com/w3c/ttml2/>, or send an email to <public-tt@w3.org>.

There are no formal objections.

Patent disclosures relevant to this specification may be found on the Timed Text Working Group's patent disclosure page in conformance with W3C policy:
  https://www.w3.org/2004/01/pp-impl/34314/status

This Call for Implementations follows section 6.4 “Candidate Recommendation" of the W3C Process Document:
  https://www.w3.org/2018/Process-20180201/#candidate-rec

Timed Text Markup Language 2 (TTML2)
W3C Candidate Recommendation 28 June 2018

This Version:
   https://www.w3.org/TR/2018/CR-ttml2-20180628/

Latest Published Version:
   https://www.w3.org/TR/ttml2/


Abstract

This document specifies the Timed Text Markup Language (TTML), Version 2, also known as TTML2, in terms of a vocabulary and semantics thereof.

The Timed Text Markup Language 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.

It 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, TTML Content may be used directly as a distribution format, for example, providing a standard content format to reference from a <track>element in an [HTML 5.2] document, or a <text> or <textstream> media element in a [SMIL 3.0] 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 https://www.w3.org/TR/.

This is the Second Candidate Recommendation (CR2) of the Timed Text Markup Language 2 (TTML2), and is intended to be progressed to a W3C Recommendation. If you wish to make comments regarding this document, please file an issue on GitHub or send email to public-tt@w3.org (subscribe, archives) with a subject line starting with [ttml2]. The deadline for comments is 26 July 2018.

The W3C publishes a Candidate Recommendation to indicate that the document is believed to be stable and to encourage implementation by the developer community. This Candidate Recommendation is expected to advance to Proposed Recommendation no earlier than 9 August 2018.

For this specification to exit CR, the following criteria must be met, as documented in the Working Group's implementation report. For each feature introduced in this specification:

	• At least two independent implementations must support the feature. If both transformation semantics and presentation semantics are defined for the feature, then at least one implementation must be a transformation processor and at least one implementation must be a presentation processor;
	• At least one of those implementations must be a validating processor that successfully verifies valid or invalid use of the feature as applicable.
The following features are at-risk, and may be dropped during the CR period:

	• #animation-version-2
	• #audio
	• #audio-description
	• #audio-speech
	• #border-radii
	• #bpd
	• #display-inlineBlock
	• #embedded-audio
	• #extent-measure
	• #font
	• #fontSelectionStrategy-character
	• #gain
	• #ipd
	• #lineShear
	• #pan
	• #pitch
	• #region-implied-animation
	• #rubyAlign-withBase
	• #shear
	• #speak
	• #speech
	• #textOrientation-sideways-LR
	• #validation

The term “at-risk” is a W3C Process term-of-art, and does not necessarily imply that the feature is in danger of being dropped or delayed. It means that the Working Group believes the feature may have difficulty being interoperably implemented in a timely manner, and marking it as such allows the Working Group to drop the feature if necessary when transitioning to the Proposed Recommendation stage without having to publish a new Candidate Recommendation omitting the feature.

A cumulative summary of all changes applied to this version since the current (TTML1, 2nd Edition) Recommendation was published is available at Timed Text Markup Language 2 (TTML2) Change Summary. An abbreviated list of changes affecting language syntax can be found at U Changes to Vocabulary from TTML1.

This document has been produced by the Timed Text (TT) Working Group as part of the W3C Video in the Web Activity, following the procedures set out for the W3C Process. The authors of this document are listed in the header of this document.

Publication as a Candidate Recommendation does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.

This document was produced by a group operating under the W3C Patent Policy. W3C maintains a 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 Essential Claim(s) must disclose the information in accordance with section 6 of the W3C Patent Policy.

This document is governed by the 1 February 2018 W3C Process Document.
