Dubbing and Audio description Profiles of TTML2 https://www.w3.org/TR/2025/CR-dapt-20250311/ feedback due by: April 8, 2025 Published by Timed Text Working Group Abstract This specification defines DAPT , a TTML -based file format for the exchange of timed text content in dubbing and audio description workflows. Status of the Document This section describes the status of this document at the time of its publication. 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 document incorporates a registry section and defines registry tables, as defined in the [w3c-process] requirements for w3c registries. Updates to the document that only change registry tables can be made without meeting other requirements for Recommendation track updates, as set out in Updating Registry Tables; requirements for updating those registry tables are normatively specified within H. Registry Section. Please see the Working Group's implementation report. For this specification to exit the CR stage, at least 2 independent implementations of every feature defined in this specification but not already present in [TTML2] need to be documented in the implementation report. The Working Group does not require that implementations are publicly available but encourages them to be so. A list of the substantive changes applied since the initial Working Draft is found at substantive-changes-summary.txt. The Working Group has identified the following at risk features: Issue 218 : At-risk: support for `src` attribute in `<audio>` for external resource PR-must-have Possible resolution to #113. Issue 219 : At-risk: support for `<source>` element child of `<audio>` for external resource PR-must-have Possible resolution to #113. Issue 220 : At-risk: support for `src` attribute of `<audio>` element pointing to embedded resource PR-must-have Possible resolution to #114 and #115. The link to #115 is that this implies the existence of some referenceable embedded audio resource too, which one of the options described in #115. Issue 221 : At-risk: support for `<source>` child of `<audio>` element pointing to embedded resource PR-must-have Possible resolution to #114 and #115. The link to #115 is that this implies the existence of some referenceable embedded audio resource too, which one of the options described in #115. Issue 222 : At-risk: support for inline audio resources PR-must-have Possible resolution to #115. Issue 223 : At-risk: each of the potential values of `encoding` in `<data>` PR-must-have Possible resolution to #117. Issue 224 : At-risk: support for the `length` attribute on `<data>` PR-must-have Possible resolution to #117. Issue 239 : At-risk: Script Event Grouping and Script Event Mapping PR-must-have Support for the #scriptEventGrouping and #scriptEventMapping features, together, is at risk pending implementer feedback. At risk features may be be removed before advancement to Proposed Recommendation. This document was published by the Timed Text Working Group as a Candidate Recommendation Snapshot using the Recommendation track. Publication as a Candidate Recommendation does not imply endorsement by W3C and its Members. A Candidate Recommendation Snapshot has received wide review, is intended to gather implementation experience, and has commitments from Working Group members to royalty-free licensing for implementations. Future updates to this specification may incorporate new features . This Candidate Recommendation is not expected to advance to Proposed Recommendation any earlier than 08 April 2025. 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.
