Timed Text Working Group Charter

Deliverables

More detailed milestones and updated publication schedules are available on the group publication status page.

Draft state indicates the state of the deliverable at the time of the charter approval. Expected completion indicates when the deliverable is projected to become a Recommendation, or otherwise reach a stable state.

Success Criteria

In order to advance to Proposed Recommendation, each normative feature is expected to meet the requirements set out in §3.1 to demonstrate adequate implementation experience.

Each Recommendation-track Technical Report:

• SHOULD contain a section detailing all known security and privacy implications for implementers, Web authors, and end users.
• SHOULD have an associated testing plan, starting from the earliest drafts.
• SHOULD contain a section on accessibility that describes the benefits and impacts, including ways that features defined in the Technical Report can be used to address them, and recommendations for maximising accessibility in implementations.
• SHOULD address the Media Accessibility User Requirements
• SHOULD contain a section discussing interoperability with previous versions, if any, of the Technical Report, and other relevant specifications.

To promote interoperability, all normative changes made to Technical Reports SHOULD have associated tests.

Coordination

For all specifications, this Working Group will seek horizontal review for accessibility, internationalization, performance, privacy, and security with the relevant Working and Interest Groups, and with the TAG. Invitation for review must be issued during each major standards-track document transition, including FPWD. The Working Group is encouraged to engage collaboratively with the horizontal review groups throughout development of each specification. The Working Group is advised to seek a review at least 3 months before first entering CR and is encouraged to proactively notify the horizontal review groups when major changes occur in a specification following a review.

Additional technical coordination with the following Groups will be made, per the W3C Process Document:

Communication

Technical discussions for this Working Group are conducted in public: the meeting minutes from teleconference and face-to-face meetings will be archived for public review, and technical discussions and issue tracking will be conducted in a manner that can be both read and written to by the general public. Working Drafts and Editor's Drafts of specifications will be developed in public repositories and may permit direct public contribution requests. The meetings themselves are not open to public participation, however.

Information about the group (including details about deliverables, issues, actions, status, participants, and meetings) will be available from the Timed Text Working Group home page.

Most Timed Text Working Group teleconferences will focus on discussion of particular specifications, and will be conducted on an as-needed basis.

This Working Group primarily conducts its technical work on the public mailing list public-tt@w3.org (archive) or GitHub issues. The public is invited to review, discuss and contribute to this work.

The Working Group MAY use a Member-confidential mailing list member-tt@w3.org (archive) for administrative purposes and, at the discretion of the Chairs and members of the group, for member-only discussions in special cases when a participant requests such a discussion.

Decision Policy

This group will seek to make decisions through consensus and due process, per the W3C Process Document (section 3.3). Typically, an editor or other participant makes an initial proposal, which is then refined in discussion with members of the group and other reviewers, and consensus emerges with little formal voting being required.

However, if a decision is necessary for timely progress and consensus is not achieved after careful consideration of the range of views presented, the Chairs may call for a group vote and record a decision along with any objections.

To afford asynchronous decisions and organizational deliberation, any resolution (including publication decisions) taken in a face-to-face meeting or teleconference will be considered provisional. A call for consensus (CfC) will be issued for all resolutions (for example, via email, GitHub issue or web-based survey), with a response period 10 working days, depending on the chair's evaluation of the group consensus on the issue. If no objections are raised by the end of the response period, the resolution will be considered to have consensus as a resolution of the Working Group.

All decisions made by the group should be considered resolved unless and until new information becomes available or unless reopened at the discretion of the Chairs or the Director.

This charter is written in accordance with the W3C Process Document (Section 3.4, Votes) and includes no voting procedures beyond what the Process Document requires.

Patent Policy

This Working Group operates under the W3C Patent Policy (Version of 15 September 2020). To promote the widest adoption of Web standards, W3C seeks to issue Web specifications that can be implemented, according to this policy, on a Royalty-Free basis.

Licensing

For each deliverable the Working Group MAY choose either the W3C Document license or the W3C Software and Document license.
