The World Wide Web Consortium (W3C) Media Annotations Working Group has published a Last Call Working Draft of "API for Media Resources 1.0." This specification defines an API to access metadata information related to media resources on the Web. The overall purpose is to provide developers with convenient access to metadata information stored in different metadata formats. The API provides means to access the set of metadata properties defined in the Ontology for Media Resources 1.0 specification. Comments are welcome through 07 August. Learn more about the Video in the Web Activity. http://www.w3.org/2008/WebVideo/Annotations/, http://www.w3.org/TR/2011/WD-mediaont-api-1.0-20110712/

W3C Extends HTML Working Charter: HTML5 Last Call in May 2011 and Recommendation in 2014.
The Worldwide Web Consortium (W3C) extended the charter of the HTML Working Group, reaffirming the commitment for HTML5 to reach Last Call in May 2011, and announcing plans to reach Recommendation by 2014. W3C is developing a comprehensive test suite to help achieve broad interoperability for the full specification. "Stable specifications are useful targets for interoperability at the same time that innovation never ceases". http://www.w3.org/News/2011#entry-9015, http://www.w3.org/TR/html5/

The W3C's Web Performance Working Group is working on a specification to define 20 "fine-grained" metrics to measure the duration of just about every aspect of a web user's navigation behavior. The W3C's working draft of the Navigation Timing Specification is in the "last call for comments" phase. After being finalized, it will specify 20 measurements for every page visited. http://test.w3.org/webperf/specs/NavigationTiming/

The Internet Society announced a 1M USD donation to the World Wide Web Consortium (W3C). This donation, the second installment of the Internet Society’s 2009 pledge of 2.5M USD over three years, will support the evolution of W3C as an organization that creates open Web standards. Both organizations have closely aligned views and strongly support the ongoing evolution of the open Internet as an invaluable platform for innovation. As active participants in the development of the open standards that ensure that the various parts of the system interoperate, both the Internet Society and W3C work to forge the strong partnerships among the various organizations that form this Internet Ecosystem. http://isoc.org

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. http://www.w3.org/html/

The SPARQL Working Group has published a First Public Working Draft of  "SPARQL 1.1 Federation Extensions," which defines extensions to the SPARQL Query Language to support distributed SPARQL query execution. The group also published 5 updates, listed below. The group seeks feedback, particularly on open issues identified in each document. Features: SPARQL 1.1 Query adds support for aggregates, subqueries, projected expressions, and negation to the SPARQL query language; SPARQL 1.1 Update defines an update language for RDF graphs; SPARQL 1.1 Service Description defines a vocabulary and discovery mechanism for describing the capabilities of a SPARQL endpoint; SPARQL 1.1 Uniform HTTP Protocol for Managing RDF Graphs describes the use of the HTTP protocol for managing named RDF graphs on an HTTP server; SPARQL 1.1 Entailment Regimes defines conditions under which SPARQL queries can be used with entailment regimes such as RDF, RDF Schema, OWL, or RIF. http://www.w3.org

The WebCGM Working Group has published a W3C Recommendation of "WebCGM 2.1." Computer Graphics Metafile (CGM) is an ISO standard, defined by ISO/IEC 8632:1999, for the interchange of 2D vector and mixed vector/raster graphics. WebCGM is a profile of CGM, which adds Web linking and is optimized for Web applications in technical illustration, electronic documentation, geophysical data visualization, and similar fields. WebCGM aims to balance graphical expressive power  with simplicity and implementability. A small set of standardized metadata elements supports the functionalities of hyperlinking and document navigation, picture structuring and layering, and enabling search and query of WebCGM picture content. WebCGM 2.1 refines and completes the features found in WebCGM 2.0. http://www.w3.org/

The W3C (World Wide Web Consortium) Mobile Web Test Suites Working Group released a second web compatibility test for mobile browsers. Based on the same idea of evaluating support of a number of Web technologies at a glance as in the first Web Compatibility Test published in July 2008, this second version features a number of more recent technologies that promise to make Web browsers more powerful, in particular on mobile devices.

The W3C (World Wide Web Consortium) Math Working Group has published a Proposed Recommendation of "XML Entity Definitions for Characters." This document presents a completed listing harmonizing the known uses in math and science of character entity names that appear throughout the XML world and Unicode. This document is the result of years of employing entity names on the Web. There were always a few named entities used for special characters in HTML, but a flood of new names came with the symbols of mathematics. Comments are welcome through 11 March.

The World Wide Web Consortium (W3C) Cascading Style Sheets (CSS) Working Group has published a Last Call Working Draft of "CSS Styling Attributes Level 1." Markup languages such as HTML and SVG provide a styling attribute on most elements, to hold a fragment of a style sheet that applies to those elements. One of the possible style sheet languages is CSS. This draft describes the syntax and interpretation of the CSS fragment that can be used in such styling attributes. Comments are welcome through 09 February. http://www.w3.org/Style/
