- Develop and publish information about accessibility of web technology, including guidance for technology developers, accessibility user requirements for technologies, and information about accessibility principles in general.
- Research accessibility risks and solutions for emerging web-enabled devices and web technologies, such as (but not limted to) artificial intelligence, authentication, automotive interfaces, digital publications, graphics and media, mobile communications devices, payments, tablets, virtual and augmented and mixed reality, Web-enabled television, Web of Things, etc.;
- Develop technological accessibility solutions as stand-alone technologies or as components of other web technologies that could become W3C Recommendations, including but not limited to personalization features and automated pronunciation guidance.
Out of Scope
The following features are out of scope, and will not be addressed by this Working group.
- Engineering accessibility solutions for technologies in scope of other W3C groups.
- Addressing accessibility of technologies that do not interact with web content.
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.
The Working Group will deliver the following W3C normative specifications:
- May need to recharter early to add Pronunciation
- Do Personalization modules in "other duties as assigned" mode
- Remove COGA
- Personalization Semantics Content Module
This specification will provide personalization semantics and vocabularies that can be used to annotate web content enabling user agents to augment or adapt content to various user scenarios based on the user’s personalization settings or preferences.

- Adopted Working Draft: The title, stable URL, and publication date of the Adopted Working Draft which will serve as the basis for work on the deliverable.
- Reference Draft: The title, stable URL, and publication date of the most recent Reference Draft or Candidate Recommendation which triggered an Exclusion Opportunity per the Patent Process. Exclusion period began; Exclusion period ended. (this charter assistant helps in producing the list. use the proper wgid)
- Produced under Working Group Charter: The stable URL of the Working Group charter under which the most recent Reference Draft or Candidate Recommendation was published.
Other non-normative documents may be created such as:
- Supporting documents for Personalization such as Personalization Semantics Explainer and Requirements for Personalization Semantics, etc.;
- Supporting documents for Pronunciation such as Explainer: Improving Spoken Presentation, Pronunciation Gap analysis and use cases, Pronunciation User Scenarios, best practices, etc.;
- Supporting resources for Specification Review such as Framework for Accessible Specification of Technologies and FAST checklist, Reviews of web technology specifications sent to maintaining entities, and Working Group Notes to formalize accessibility knowledge on specific topics as the need arises;
- Accessibility User Requirements such as Media Accessibility User Requirements and others;
- Information about accessibility needs of specific user groups, such as Making content usable for people with cognitive and learning disabilities;
- Research reports addressing, as needed, gaps identified during accessibility reviews of draft specifications, and/or technical questions emerging through other aspects of accessibility reviews;
- Test suite and implementation reports for normative specifications.
Detailed milestones and updated publication schedules are available on the group publication status page.
- March 2021: CR of Personalization Semantics Content Module
- April 2023: PR of Personalization Semantics Content Module

In order to advance to Proposed Recommendation, each normative specification is expected to have at least two independent implementations of every feature defined in the specification.
Each specification should contain a section detailing all known security and privacy implications for implementers, Web authors, and end users. Each specification should contain a section on accessibility that describes the benefits and impacts, including ways specification features can be used to address them, and recommendations for maximising accessibility in implementations.
There should be testing plans for each specification, starting from the earliest drafts. To promote interoperability, all changes made to specifications should have tests.
- Advancement of personalization support on the web via specifications published by this group and features incorporated into other work.
- Improved accessibility of web technologies as measured by the activity of accessibility proponents in coordination with APA, accepted comments on specifications, and other tracked Working Group dialog;
- Release of Web Technology Accessibility Guidelines as Working Group Note and indications of its use by other Working Groups;
- Documentation of new accessibility issues and solutions, potentially with spin-off work begun;
- Record of active and sustained coordination between APA and other stakeholders.
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:

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.
The group encourages questions, comments and issues on its public mailing lists and document repositories, as described in Communication.
The group also welcomes non-Members to contribute technical submissions for consideration upon their agreement to the terms of the W3C Patent Policy.
Participants in the group are required (by the W3C Process) to follow the W3C Code of Ethics and Professional Conduct.
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 on a public repository and may permit direct public contribution requests. The meetings themselves are not open to public participation, however, except by explicit one-time invitation from the chair(s).
Information about the group (including details about deliverables, issues, actions, status, participants, and meetings) will be available from the Accessible Platform Architectures Working Group home page.
This group primarily conducts its technical work email@example.com (archive) and GitHub. Additional communication channels are also used. The public is invited to review, discuss and contribute to this work.
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.
This group will seek to make decisions through consensus and due process, per the W3C Process Document (section 3.3). The Working Group maintains specific procedures to establish and measure consensus and address objections in the Accessible Platform Architectures Working Group Decision Policy. 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.
This Working Group operates under the W3C Patent Policy (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 W3C Patent Policy Implementation.
If the Director approves the proposed W3C Patent Policy (Draft dated 23 June 2020), without making subtantives changes following the Advisory Committee review, this charter will be updated in place to use the updated Patent Policy.
This Working Group will use the W3C Document license for Recommendation-track deliverables and the W3C Software and Document license for Note-track deliverables and licensed non-TR publications.
