<h1 id="title">Web Fonts Working Group Charter</h1>
<p class="mission">The <strong>mission</strong> of the <a href="https://www.w3.org/Fonts/WG">Web Fonts Working Group</a> is to develop specifications that allow the interoperable deployment of downloadable fonts on the Web.</p>
<p>WOFF 1.0 and 2.0 are widely implemented W3C Recommendations.
However, for fonts with many glyphs (such as are typically used for Chinese and Japanese, for example), even with the compression provided by WOFF, download sizes are still large. Static subsetting runs the risk of missing glyphs, or some text being rendered in a fallback font. Early experiments have demonstrated
the feasibility of a font enrichment API, where a server delivers a font with minimal glyph repertoire and the client can query the full repertoire and request additional subsets on-the-fly. The API takes care of progressively enriching the downloaded font, without requiring cumbersome CSS manipulations or multiple, separate font files. This API could be implemented as a script library, or as a native browser API.

<h2>Coordination</h2>
<p>For all specifications, this <i class="todo">Working</i> Group will seek <a href="https://www.w3.org/Guide/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> and at least 3 months before <a href="https://www.w3.org/Consortium/Process/#RecsCR" title="Candidate Recommendation">CR</a>, and should be issued when major changes occur in a specification.</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>
<p class="todo">In addition to the above catch-all reference to horizontal review which includes accessibility review, please check with chairs and staff contacts of the <a href="https://www.w3.org/WAI/APA/">Accessible Platform Architectures Working Group</a> to determine if an additional liaison statement with more specific information about concrete review issues is needed in the list below.</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>
</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 on a public repository, 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="">Web Fonts Working Group home page.</a>
</p>
<p>
Most Web Fonts 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 <i class="todo">pick one, or both, as appropriate:</i> on the public mailing list <a class="todo" id="public-name" href="mailto:public-[email-list]@w3.org">public-<i class="todo">[email-list]</i>@w3.org</a> (<a class="todo" href="https://lists.w3.org/Archives/Public/public-[email-list]/">archive</a>)
<i class="todo">or</i> on <a class="todo" id="public-github" href="[link to Github repo]">GitHub issues</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 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, but 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 and/or web-based survey), with a response period from one week to 10 working days, depending on the chair's evaluation of the group consensus on the issue.
If no objections are raised on the mailing list by the end of the response period, the resolution will be considered to have consensus as a resolution of the <i class="todo">Working</i> 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/policies#Votes">W3C Process Document (Section 3.4, Votes)</a>, and includes no voting procedures beyond what the Process Document requires.

<p><i class="todo">[Keep 'Patent Policy' for a Working Group, 'Patent Disclosures' for an Interest Group]</i></p>
<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 5 February 2004 updated 1 August 2017). To promote the widest adoption of Web standards, W3C seeks to issue Recommendations that can be implemented, according to this policy, on a Royalty-Free basis.
For more information about disclosure obligations for this group, please see the <a href="https://www.w3.org/2004/01/pp-impl/">W3C Patent Policy Implementation</a>.
</p>
<h2>Patent Disclosures </h2>
<p>The Interest Group provides an opportunity to
share perspectives on the topic addressed by this charter. W3C reminds
Interest Group participants of their obligation to comply with patent
disclosure obligations as set out in <a shape="rect" href="https://www.w3.org/Consortium/Patent-Policy/#sec-Disclosure">Section
6</a> of the W3C Patent Policy. While the Interest Group does not
produce Recommendation-track documents, when Interest Group
participants review Recommendation-track specifications from Working
Groups, the patent disclosure obligations do apply. For more information about disclosure obligations for this group,
please see the <a href="https://www.w3.org/2004/01/pp-impl/">W3C
