W3C And WHATWG Partnered On Single HTML And DOM Specifications

Both have signed an MoU to work together on the development of a single version of the HTML and DOM specifications.

Recently, World Wide Web Consortium (W3C) announced that W3C and the Web Hypertext Application Technology Working Group (WHATWG) have signed an agreement to collaborate on the development of a single version of the HTML and DOM specifications.
W3C and WHATWG both believe that diverging the specifications and splitting the community to focus on different documents, has been costly and inefficient.

  • Both the companies will work together on HTML and DOM, in the WHATWG repositories, in order to produce a Living Standard and Recommendation/Review Draft-snapshots.
  • WHATWG will maintain the HTML and DOM Living Standards, while W3C will facilitate community work directly in the WHATWG repositories.
  • W3C will also stop independent publishing of a designated list of specifications related to HTML and DOM. It will work to take WHATWG Review Drafts to W3C Recommendations
The company said that W3C and WHATWG had been working on effective partnership mechanisms since December 2017. In September and December 2018 during the extensions of the Web Platform Working Group, W3C noted that while negotiations continued to make a single authoritative specification for HTML and DOM, the specifications that were part of the negotiations with the WHATWG would not be advanced on the W3C Recommendation track.
