First Drafts of Two Provenance Specifications Published

10 January 2012 | Archive

The Provenance Working Group has published two First Public Working Drafts:

  • PROV-AQ: Provenance Access and Query which specifies how to use standard Web protocols, including HTTP, to obtain information about the provenance of Web resources. This is part of the larger W3C provenance framework. Provenance refers to the sources of information, such as people and processes, involved in producing or delivering Web documents, data, and resources.
  • PROV Model Primer which provides an intuitive introduction and guide to the core data model for building representations of the entities, people and processes involved in producing a piece of data or thing in the world.

W3C Invites Implementations of Multimodal Architecture and Interfaces

12 January 2012 | Archive

The Multimodal Interaction Working Group invites implementation of the Candidate Recommendation of Multimodal Architecture and Interfaces. The specification describes a loosely coupled architecture for multimodal user interfaces, which allows for co-resident and distributed implementations, and focuses on the role of markup and scripting, and the use of well defined interfaces between its constituents.

Two Drafts Published by the HTML Data Task Force

12 January 2012 | Archive

The HTML Data Task Force of the Semantic Web Interest Group has published two documents today:

  • The HTML Data Guide aims to help publishers and consumers of HTML data. With several syntaxes (microformats, microdata, RDFa) and vocabularies (, Dublin Core, microformat vocabularies, etc.) to choose from, it provides guidance on deciding what to choose in a way that meets the publisher's or consumer's needs.
  • The Microdata to RDF describes processing rules that may be used to extract RDF from an HTML document containing microdata.

Both documents are Working Drafts, with the goal of publishing a final version as Interest Group Notes. Comments and feedbacks are welcome; please send them to the mailing list.

Last Call: CSS Image Values and Replaced Content Module Level 3

12 January 2012 | Archive

The Cascading Style Sheets (CSS) Working Group has published a Last Call Working Draft of CSS Image Values and Replaced Content Module Level 3. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. This module contains the features of CSS level 3 relating to the <image> type and replaced elements. It includes and extends the functionality of CSS level 2, which builds on CSS level 1. The main extensions compared to level 2 are the generalization of the <url> type to the <image> type, several additions to the ‘<image>’ type, a generic sizing algorithm for images and other replaced content in CSS, and several properties controlling the interaction of replaced elements and CSS's layout models. Comments are welcome through 07 February. Learn more about the Style Activity.

11 January 2012 | Archive

The W3C Advisory Committee has elected Robin Berjon (unaffiliated) and re-elected Henry Thompson (U. of Edinburgh) to the W3C Technical Architecture Group (TAG). W3C Director and TAG co-Chair Tim Berners-Lee also re-appointed Noah Mendelsohn (unaffiliated) and Jonathan Rees (Creative Commons). They join continuing participants Peter Linss (HP), Ashok Malhotra (Oracle), Larry Masinter (Adobe), and Jeni Tennison (unaffiliated). Many thanks to Dan Appelquist whose term ends this month. The mission of the TAG is to build consensus around principles of Web architecture and to interpret and clarify these principles when necessary, to resolve issues involving general Web architecture brought to the TAG, and to help coordinate cross-technology architecture developments inside and outside W3C. Read the TAG's December 2011 finding Identifying Application State and learn more about their public work plan.

Last Call: WAI-ARIA 1.0 User Agent Implementation Guide

10 January 2012 | Archive

The Protocols and Formats Working Group has published a Last Call Working Draft of WAI-ARIA 1.0 User Agent Implementation Guide. This document describes how user agents should support keyboard navigation and respond to roles, states, and properties provided in Web content via WAI-ARIA. These features are used by authors creating accessible rich internet applications. Users often access the content using assistive technologies that rely on platform accessibility APIs to obtain and interact with information from the page. The WAI-ARIA User Agent Implementation Guide defines how implementations should expose content to accessibility APIs, helping to ensure that this information appears in a manner consistent with author intent. This document is part of the WAI-ARIA suite described in the WAI-ARIA Overview. Comments are welcome through 17 February. Learn more about the WAI Technical Activity.
