<h2>Scope</h2>
<p>The deployment of the QUIC protocol standardized in IETF (e.g. in the context of HTTP3) is expected to make QUIC support widely available, opening up the possibility to establish new types of network connections in Web applications for client-server data transfer (e.g. unreliable, unordered).</p>
<p>The WebTransport Working Group, in collaboration with the <a href="https://datatracker.ietf.org/wg/webtrans/about/">IETF WebTransport Working Group</a> develops APIs that enable Web developers to make use of these new network capabilities, including possible fallback mechanisms to handle scenarios when a QUIC connection cannot be established.</p>
<p>These capabilities are expected to be useful in a wide variety of contexts where network performance has perceivable impacts on user experience, such as media streaming or cloud gaming.</p>

</section>
<section id="success-criteria">
<h2>Success Criteria</h2>
<p>In order to advance to <a href="https://www.w3.org/Consortium/Process/#RecsPR" title="Proposed Recommendation">Proposed Recommendation</a>, each specification is expected to have <a href="https://www.w3.org/Consortium/Process/#implementation-experience">at least two independent implementations</a> of each feature defined in the specification.</p>
<p>Each specification should contain a section detailing any <a href='https://www.w3.org/TR/security-privacy-questionnaire/'>known security and privacy implications</a>, and suggested mitigation strategies for implementers, web authors, and end users. The group should not publish a specification if acceptable mitigation strategies cannot be found.</p>
<p>There should be testing plans for each specification, starting from the earliest drafts.</p>
<p>To promote interoperability, all changes made to specifications after implementations emerge should have <a href='https://www.w3.org/2019/02/testing-policy.html'>tests</a>.</p>
</section>
<section id="coordination">
<h2>Coordination</h2>
<p>For all specifications, this Working Group will seek <a href="https://www.w3.org/Guide/process/charter.html#horizontal-review">horizontal review</a> for
accessibility, internationalization, performance, privacy, and security with the relevant Working and
Interest Groups, and with the <a href="https://www.w3.org/2001/tag/" title="Technical Architecture Group">TAG</a>.
Invitation for review must be issued during each major standards-track document transition, including
<a href="https://www.w3.org/Consortium/Process/#RecsWD" title="First Public Working Draft">FPWD</a>. 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
<a href="https://www.w3.org/Consortium/Process/#RecsCR" title="Candidate Recommendation">CR</a> and is encouraged
to proactively notify the horizontal review groups when major changes occur in a specification following a review.</p>
<p>Additional technical coordination with the following Groups will be made, per the <a href="https://www.w3.org/Consortium/Process/#WGCharter">W3C Process Document</a>:</p>
<section>
<h3 id="w3c-coordination">W3C Groups</h3>
<dl>
<dt><a href="https://www.w3.org/groups/wg/htmlwg">HTML Working Group</a></dt>
<dd>The HTML Working Group works together with the WHATWG to produce the W3C Recommendation of HTML. The HTML specification defines the WebSockets API which may play a role in fallback scenarios when a WebTransport connection cannot be established.</dd>
<dt><a href="https://www.w3.org/groups/wg/webrtc">Web Real-Time Communications Working Group</a></dt>
<dd>The WebRTC API developed by the WebRTC Working Group enables data transfer between peers with similar charactestics to the ones enabled by WebTransport, and may consider adopting the WebTransport API for peer-to-peer data transfer.</dd>
<dt><a href="https://www.w3.org/2011/webtv/">Media and Entertainment Interest Group</a></dt>

Participation
</h2>
<p>
To be successful, this Working Group is expected to have 6 or more active participants for its duration, including representatives from the key implementors of this specification, and active Editors and Test Leads for each specification. The Chairs, specification Editors, and Test Leads are expected to contribute half of a working day per week towards the Working Group. There is no minimum requirement for other Participants.
</p>
<p>
The group encourages questions, comments and issues on its public mailing lists and document repositories, as described in <a href='#communication'>Communication</a>.
</p>
<p>
The group also welcomes non-Members to contribute technical submissions for consideration upon their agreement to the terms of the <a href="https://www.w3.org/Consortium/Patent-Policy/">W3C Patent Policy</a>.
</p>
<p>Participants in the group are required (by the <a href="https://www.w3.org/Consortium/Process/#ParticipationCriteria">W3C Process</a>) to follow the
W3C <a href="https://www.w3.org/Consortium/cepc/">Code of Ethics and Professional Conduct</a>.</p>
</section>
<section id="communication">
<h2>
Communication
</h2>
<p id="public">
Technical discussions for this Working Group are conducted in <a href="https://www.w3.org/Consortium/Process/#confidentiality-levels">public</a>: 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.
</p>
<p>
Information about the group (including details about deliverables, issues, actions, status, participants, and meetings) will be available from the <a href="https://www.w3.org/groups/wg/webtransport">WebTransport Working Group home page.</a>
</p>
<p>
Most WebTransport Working Group teleconferences will focus on discussion of particular specifications, and will be conducted on an as-needed basis.
</p>
<p>
This group primarily conducts its technical work on its <a id="public-github" href="https://github.com/w3c/webtransport">repositories' GitHub issues</a> and its public mailing list <a href="mailto:[email protected]">[email protected]</a> (<a href="https://lists.w3.org/Archives/Public/public-webtransport/">archive</a>).
The public is invited to review, discuss and contribute to this work.
</p>
<p>
The group may use a Member-confidential mailing list 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.
</p>
</section>
<section id="decisions">
<h2>
Decision Policy
</h2>
<p>
This group will seek to make decisions through consensus and due process, per the <a href="https://www.w3.org/Consortium/Process/#Consensus">W3C Process Document (section 5.2.1, Consensus)</a>. 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.</p>
<p>
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.
</p>
<p>
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 from <span id='cfc'>one week to 10 working days</span>, 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.
</p>
<p>
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.
</p>
<p>
This charter is written in accordance with the <a href="https://www.w3.org/Consortium/Process/#Votes">W3C Process Document (Section 5.2.3, Deciding by Vote)</a> and includes no voting procedures beyond what the Process Document requires.
