The HTML Working Group has published the First Public Working Draft of HTML+RDFa. RDFa is intended to solve the problem of machine-readable data in HTML documents. RDFa provides a set of HTML attributes to augment visual data with machine-readable hints. Using RDFa, authors may turn their existing human-visible text and links into machine-readable data without repeating content. This specification defines rules and guidelines for adapting the RDF in XHTML: Syntax and Processing (RDFa) specification for use in the HTML5 and XHTML5 members of the HTML family. The rules defined in this document not only apply to HTML5 documents in non-XML and XML mode, but also to HTML4 documents interpreted through the HTML5 parsing rules. Learn more about the HTML Activity.

The Device APIs and Policy Working Group has published a First Draft of a Group Note of Device APIs Requirements. These are the requirements intended to be met in the development of client-side APIs that enable the creation of Web Applications and Web Widgets that interact with devices services such as Calendar, Contacts, Camera, etc. Learn more about the Ubiquitous Web Applications Activity.

The Cascading Style Sheets (CSS) Working Group has published a Last Call Working Draft of CSS Backgrounds and Borders Module Level 3.

A Patent Advisory Group (PAG) for the Web Applications Working Group published its report, which suggests that W3C should continue the work on the Widgets 1.0: Updates Specification. W3C launched the PAG when Apple Computer, Inc excluded patent claims from the W3C Royalty-Free licensing commitment. The Group concluded that the US Patent Number 5,764,992 is considered not essential according to Section 8 of the W3C Patent Policy, and provided a set of Recommendations to the Web Applications Working Group.

The Web Applications Working Group has published a Last Call Working Draft of Widgets 1.0: Widget URIs. Resources inside a widget package are identified and located using a method that is specific to widgets technology. Widget URIs reflect this by providing these specific locators with their own syntax so that resources in widget packages can be readily identified. Comments are welcome through 10 November.

The Product Modelling Incubator Group has published their final report. The mission of the Incubator Group was to enable the use of the (Semantic) Web for Product Modelling (PM): the definition, storage, exchange and sharing of product data. Product data is information about the structure and behaviour of things that are realized in industrial processes. So principally product data is about things that are manmade, but it can also be about things in the natural world that interact with those industrial processes and/or its resulting products. The report describes the role and scope of product data, and initial work in two technical areas (1) quantities, units, and scales; and (2) product structure - the decomposition of wholes in parts and the interconnection relationships between these parts. This publication is part of the Incubator Activity, a forum where W3C Members can innovate and experiment. This work is not on the W3C standards track.

The Web Applications Working Group has published the First Public Working Draft of Widgets 1.0: View Modes Media Feature. This specification is part of the Widgets 1.0 family of specifications. It introduces a feature that allows designers to specify different presentations according to "view modes" (e.g., when a widget is running like any other application, when it is running without "chrome," or when occupying all of the screen).

The third and possibly final run of the successful online training course An Introduction to W3C Mobile Web Best Practices is due to start on Monday, 12 October. Participants work at their own pace at times to suit them throughout the 9-week course. The program is well-suited to developers with experience of desktop design and production who wish to apply their HTML and CSS skills to the mobile environment. A mixture of lectures and assignments provide hands-on practical experience in using W3C's Mobile Web Best Practices. Participants will work with both W3C instructors and peers who can share experiences about the real-world challenges of mobile Web design.

Comments from previous participants include:

• "Great course! I really enjoyed it. Found it challenging at times but never felt I was on my own. The forum was an essential element to making me feel part of a community. Kudos!"
• "Thanks for the cool course. I learned a lot."
• "El contenido del curso es excelente, valoro el interes que le prestan a todos los estudiantes y a los temas de los foros."

More information (including a free sample) is available about the course material, registration fee, and intended audience. Learn more about the Mobile Web Initiative.

The W3C community convenes next month in Santa Clara, California for Technical Plenary Week (TPAC) 2009, this year's edition of an annual week-long opportunity for W3C group participants to share news of progress and to address hot-button technical issues face-to-face, including the future of HTML 5, privacy challenges in an era of powerful Web Applications, and how governments are using the Web to increase transparency and accountability. This year, the Internet Society (ISOC), as part of its mission to support the development of open standards, will sponsor TPAC 2009 and actively participate in the event. In addition to ISOC representatives, participants from other standards development organizations will join in discussion about the health of the "Internet Ecosystem" during the Plenary Day. As previously announced, W3C invites the public to a Developer Gathering on 5 November. In addition, the press are invited to attend a Media Breakfast on 3 November from 7:30-8:30am (Pacific Time) for presentations on some of the key topics W3C will cover during the week. Read the press release and learn more about TPAC 2009.

The Math Working Group has published a Last Call Working Draft of A MathML for CSS profile. This document describes a profile of MathML 3.0 that could be used to capture structure of mathematical formulae in the way suitable for further CSS formatting. This profile is expected to facilitate adoption of MathML in web browsers and CSS formatters, allowing them to reuse existing CSS visual formatting model, enhanced with a few mathematics-oriented extensions, for rendering of the layout schemata of presentational MathML. Learn more about the W3C Math Activity.

The Mobile Web Best Practices Working Group has published two Last Call Working Drafts: Mobile Web Application Best Practices and Guidelines for Web Content Transformation Proxies 1.0. The former describes Best Practices for the development and delivery of Web applications on mobile devices. The recommendations expand upon statements made in the Mobile Web Best Practices, especially those that relate to the exploitation of device capabilities and awareness of the delivery context. The latter document provides guidance to implementers of Content Transformation proxies as to whether and how to transform Web content. Content Transformation proxies alter requests sent by user agents to servers and responses returned by servers so that the appearance, structure or control flow of Web applications are modified. Content Transformation proxies are mostly used to convert Web sites designed for desktop computers to a form suitable for mobile devices. Comments on both documents welcome through 6 November.
