The Working Group will maintain the <a href="https://www.w3.org/TR/did-core/">DID</a>
specification, which defines a new type of identifier that enables verifiable,
decentralized digital identity. This includes possible
<a href="https://www.w3.org/2020/Process-20200915/#correction-classes">class 1, 2, or 3 </a>
level changes on the Recommendation.
</p>
<p>
The Working Group will also seek consensus around DID Method specifications, and
may produce related documents.
</p>
<p>
The Working Group will begin working toward a specification for DID Resolution
and DID URL Dereferencing.

<section id="scope" class="scope">
<h2>Scope</h2>
<p>Beyond the maintenance of the <a href="https://www.w3.org/TR/did-core/">DID Identifiers</a> specification, the following, non-normative Working Group Notes will also be maintained by the Working Group.</p>
<ul>
<li>
<a href="https://www.w3.org/TR/did-spec-registries/">DID Specification Registries</a>, including transitioning it from a WG Note to a <a href="https://www.w3.org/2021/Process-20211102/#registries">W3C Registry</a>.

</li>
</ul>
<p>The Working Group may also publish new Working Group Notes that may be necessary to clarify, help the deployment and usage, or propose new features to the Group’s main recommendation-track deliverable.</p>
<p>
The Working Group may also publish new Working Group Notes, Editors Drafts, or
Working Drafts for DID Resolution or DID URL Dereferencing, or of DID Method
Specifications. Any new documents intended for Recommendation will be
limited to the Working Draft maturity level.

The <a href="https://www.w3.org/TR/did-spec-registries/#did-methods">DID Specification Registries</a> contains many links to examples of DID Method Specifications, some of which may be selected by the working group for development into a Recommendation.

<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 normative specification is expected to have <a href="https://www.w3.org/Consortium/Process/#implementation-experience">at least two independent implementations</a> of every feature defined in the specification.</p>
<p>Each specification should contain separate sections detailing all known security and privacy implications for implementers, Web authors, and end users.</p>
<p>There should be testing plans for each specification, starting from the earliest drafts.</p>
</section>
<section id="coordination">
<h2>Coordination</h2>
<p>For all specifications, this Working Group will seek <a href="https://www.w3.org/Guide/documentreview/#how_to_get_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>

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>

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="">Decentralized Identifier Working Group home page.</a>
</p>
<p>
Most Decentralized Identifier 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 the public mailing list <a id="public-name" href="mailto:public-did-wg@w3.org">public-did-wg@w3.org</a> ( <a href="https://lists.w3.org/Archives/Public/public-did-wg/">archive</a>) or on <a id="public-github" href="https://github.com/w3c/did-wg/">GitHub issues</a> (and specification-specific GitHub repositories and issue trackers). 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.

<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 3.3</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 3.4, Votes)</a> and includes no voting procedures beyond what the Process Document requires.
