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=""> Verifiable Credentials Working Group home page. </a> </p> <p> Most Verifiable Credentials 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-vc-wg@w3.org"> public-vc-wg@w3.org </a> ( <a href="https://lists.w3.org/Archives/Public/public-vc-wg/"> archive </a> ) or on <a id="public-github" href="https://github.com/w3c/verifiable-credentials"> GitHub issues </a> (and specification-specific GitHub repositories and issue trackers).

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 of 1 week, 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. </p> </section> <section id="patentpolicy"> <h2> Patent Policy </h2> <p> This Working Group operates under the <a href="https://www.w3.org/Consortium/Patent-Policy/"> W3C Patent Policy </a> (Version of 15 September 2020).
