This project published a document that reviews literature about

273-610: A new edition or level of the recommendation. Additionally, the W3C publishes various kinds of informative notes which are to be used as references. Unlike the Internet Society and other international standards bodies, the W3C does not have a certification program. The W3C has decided, for now, that it is not suitable to start such a program, owing to the risk of creating more drawbacks for the community than benefits. In January 2023, after 28 years of being jointly administered by

312-542: A paper on natural language usage for people with cognitive disabilities, and initial work on accessibility requirements for XML-based markup languages (XML Accessibility Guidelines).

Membership requirements are transparent except for one requirement: An application for membership must be reviewed and approved by

624-555: Is now endorsed by the W3C, indicating its readiness for deployment to the public, and encouraging more widespread support among implementors and authors. Recommendations can sometimes be implemented incorrectly, partially, or not at all, but many standards define two or more levels of conformance that developers must follow if they wish to label their product as W3C-compliant. A recommendation may be updated or extended by separately-published, non-technical errata or editor drafts until sufficient substantial edits accumulate for producing

663-569: Is the main international standards organization for the World Wide Web . Founded in 1994 and led by Tim Berners-Lee , the consortium is made up of member organizations that maintain full-time staff working together in the development of standards for the World Wide Web.

The Evaluation and Repair Tools Working Group develops technical specifications that support the accessibility evaluation and repair of Web sites. It also maintains

1287-877: The same process as other parts of the W3C. Like other W3C initiatives, the WAI consists of several working groups and Special interest groups , each with its own focus. Only working groups can produce technical reports that become W3C recommendations. A working group can sometimes delegate specific work to a task force , which then presents its results back to the working group for approval. Interest groups may produce reports (for example, as W3C Notes), but not recommendations. Each of these types of groups (working group, task force, interest group) can have one or more mailing lists. They meet through conference calls at regular intervals (typically every week or every other week) and sometimes use web-based surveys to collect input or comments from participants. They can also meet face to face (one to five times per year). In 1997 Judy Brewer has been

1326-622: The standard matures. A candidate recommendation is a version of a more mature standard than the WD. At this point, the group responsible for the standard is satisfied that the standard meets its goal. The purpose of the CR is to elicit aid from the development community on how implementable the standard is. The standard document may change further, but significant features are mostly decided at this point. The design of those features can still change due to feedback from implementors. A proposed recommendation

1365-615: The user interface on the one hand, and the content produced by the tool on the other. The working group consists of representatives from organizations that produce authoring tools, researchers, and other accessibility experts.
