The Open Web Platform
The Open Web Platform is the collection of open (royalty-free) technologies which enables the Web. Using the Open Web Platform, everyone has the right to implement a software component of the Web without requiring any approvals or waiving license fees.
This goal of this repository is to document the Open Web Platform and provide links to various helpful resources. It is intended for a general audience. If you're interested in editing these pages, please see the Community portal.
Note: There is a separate dedicated wiki for the HTML Working Group. It is intended for discussion specific to ongoing work and issues within the HTML Working Group. The main page of this wiki is really the W3C HTML page, so start there.
The W3C is working because of the contributions of each individual (from companies, organizations, or just people with passion for the Web). The Web exists because of you. The platform is defined by a list of browser technologies being currently developed, implemented and tested.
The HyperText Markup Language (HTML) is the publishing language of the World Wide Web. The first version of HTML was described by Tim Berners-Lee in late 1991. The current W3C Recommendation for HTML is HTML5.
HTML has been traditionally served with text/html mime type. When developing XHTML 1.0, XHTML 1.1, a transition to application/xhtml+xml. A minority of document less than 0.003% are being served with this latter mime type.
