MIT and currently headed by him, • Call for implementation • Maintains hundreds of standards • Call for Review of a Proposed associated with the Web, e- Recommendation commerce, and information representation • W3C Recommendation (REC). • Standards known as Recommendations which proceed through successive Drafts 23 Accessibility (All) Mobile Web Authoring Web IDL Accessible Rich Internet

technologies. • The WHATWG was founded by individuals from Apple, the Mozilla Foundation and Opera Software in 2004 • The WHATWG was formed in response to the slow development of web standards monitored by the World Wide Web Consortium (W3C), and its decision to abandon HTML in favor of XML-based technologies. • The WHATWG has a small, invitation-only steering committee called "Members" 27 www.whatwg.org Web Hypertext Application Technology Working Group 28 W3C Web Standards Process 29 Vs • The Mozilla Foundation and Opera Software presented a position paper at a W3C workshop in June 2004 focusing on developing technologies that are backwards compatible with existing browsers • The workshop concluded with a vote, 8 for, 14 against, for continuing work on HTML • W3C proceed with its XHTML 2.0 Effort • Work based upon that position paper moved to the WHATWG, and was soon renamed HTML5 30 • In 2007, W3C abandoned its XHTML 2.0 effort, offered to merge its working group with WHATWG, and adopted the HTML5 specifications as the starting point for a W3C HTML5 effort "It's time to revisit the standard and see what we can do to meet the current community needs, and to do so effectively with commitments from browser manufacturers in a visible and open way."! Tim Berners-Lee 31 Standardization Timetable • 2008:W3C/WHATWG published the First Public Working Draft of the specification • 2011:‘Last Call’ an invitation to communities inside and outside W3C to confirm the technical soundness of the specification • 2014: Target date for a ‘Recommendation’ • However: in 2012, WHATWG and W3C have decided on a degree of separation. • W3C will continue the HTML5 specification work, focusing on a single definitive standard, • This is considered as a "snapshot" by WHATWG. • The WHATWG organization will continue its work with HTML5 as a "Living Standard". The concept of a living standard is that it is never complete and is always being updated and improved 32 33 Except where otherwise noted, this content is licensed under a Creative Commons Attribution-NonCommercial 3.0 License. !
