The HTML Working Group published eight documents:

• Working Drafts of the HTML5 specification, the accompanying explanatory document HTML5 differences from HTML4, and the related non-normative reference HTML: The Markup Language.
• Working Drafts of the specifications HTML+RDFa 1.1 and HTML Microdata, which define mechanisms for embedding machine-readable data in HTML documents, and the specification HTML Canvas 2D Context, which defines a 2D immediate-mode graphics API for use with the HTML5 <canvas> element.
• HTML5: Techniques for providing useful text alternatives, which is intended to help authors provide useful text alternatives for images in HTML documents.
• Polyglot Markup: HTML-Compatible XHTML Documents, which is intended to help authors produce XHTML documents that are also compatible with non-XML HTML syntax and parsing rules.

W3C is pleased to announce the creation of the WebID Incubator Group, whose mission is to further advance for full standardization the WebID protocol, an authentication protocol that uses the SSL/TLS layer for user identification by tying the client to a profile document on the Web through placing a URI in a certificate. It is a first step to a fully standard-based browser authentication experience, but not limited to browser based authentication: peer to peer server authentication will work just as well. The Incubator Group intends to pursue work that has been evolving since 2008, grow the number of interested parties from the Social Web, security and browser communities, and integrate their feedback. The following W3C Members have sponsored the charter for this group: The Apache Software Foundation, DERI Galway, Garlik, INRIA, Nokia, OpenLink Software, Talis, Telecom Italia SpA, Vrije Universiteit Amsterdam. Read more about the Incubator Activity, an initiative to foster development of emerging Web-related technologies. Incubator Activity work is not on the W3C standards track but in many cases serves as a starting point for a future Working Group.

W3C announces the Content on the Multilingual Web Workshop, to take place 4-5 April 2011 in Pisa, Italy. Workshop participants will discuss currently available best practices and standards that help content creators, localizers, language technology developers, browser makers, and others meet the challenges of the multilingual Web. The Workshop also provides opportunities for networking that bring together the various communities involved in enabling the multilingual Web. This is the second of four Workshops being planned by W3C over the next two years as part of the MultilingualWeb European Project and is hosted by the Consiglio Nazionale delle Ricerche. Participation is free and open to anyone. However, space is limited and participants are advised to register as soon as possible. People wishing to speak should submit an outline of their proposed talk with their registration form. The deadline for speaker proposals is 1 March. For more information, see the call for participation. Learn more about W3C's Internationalization Activity.

The W3C Multimodal Interaction Working Group invites implementation of the Candidate Recommendation of Ink Markup Language (InkML). This document describes the syntax and semantics for the Ink Markup Language, a data format for representing ink entered with an electronic pen or stylus. The markup allows for the input and processing of handwriting, gestures, sketches, music and other notational languages in applications. It provides a common format for the exchange of ink data between components such as handwriting and gesture recognizers, signature verifiers, and other ink-aware modules. See the group's implementation report plan. Learn more about the Multimodal Interaction Activity.
