W3C Invites Implementations of Multimodal Architecture and Interfaces
</a>
</h3>
<p class="date"><span class="dtstart published" title="2012-01-12T10:57:52-05:00">12 January 2012</span></p>
<p>The <a href="http://www.w3.org/2002/mmi/">Multimodal Interaction Working Group</a> invites implementation of the Candidate Recommendation of <a href="http://www.w3.org/TR/2012/CR-mmi-arch-20120112/">Multimodal Architecture and Interfaces</a>. 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.

<p>The <a href="http://www.w3.org/wiki/Html-data-tf">HTML Data Task Force</a> of the <a href="http://www.w3.org/2001/sw/interest/">Semantic Web Interest Group</a> has published two documents today:</p>
<ul class="show_items">
<li>The <a href="http://www.w3.org/TR/2012/WD-html-data-guide-20120112/">HTML Data Guide</a> aims to help publishers and consumers of HTML data. With several syntaxes (microformats, microdata, RDFa) and vocabularies (schema.org, 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.</li>
<li> The <a href="http://www.w3.org/TR/2012/WD-microdata-rdf-20120112/">Microdata to RDF</a> describes processing rules that may be used to extract RDF from an HTML document containing microdata.</li>
</ul>
<p>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 <a href="mailto:public-html-data-tf@w3.org">public-html-data-tf@w3.org</a> mailing list.</p>

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

<p class="date"><span class="dtstart published" title="2012-01-12T10:13:42-05:00">12 January 2012</span></p>
<p>The <a href="http://www.w3.org/Style/CSS/members">Cascading Style Sheets (CSS) Working Group</a> has published a Last Call Working Draft of <a href="http://www.w3.org/TR/2012/WD-css3-images-20120112/">CSS Image Values and Replaced Content Module Level 3</a>. 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 <a href="http://www.w3.org/Style/">Style Activity</a>.</p>

<p>The W3C Advisory Committee has elected Robin Berjon (unaffiliated) and re-elected Henry Thompson (U. of Edinburgh) to the W3C <a href="/2001/tag/">Technical Architecture Group (TAG)</a>. 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 <a href="/2004/10/27-tag-charter.html#Mission">mission</a> 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.

<p>The <a href="http://www.w3.org/WAI/PF/">Protocols and Formats Working Group</a> has published a Last Call Working Draft of <a href="http://www.w3.org/TR/2012/WD-wai-aria-implementation-20120110/">WAI-ARIA 1.0 User Agent Implementation Guide</a>. 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.

<p>The <a href="http://www.w3.org/2008/xmlsec/">XML Security Working Group</a> has published a new Last Call Working Draft of "<a href="http://www.w3.org/TR/2012/WD-xmlenc-core1-20120105/">XML Encryption 1.1</a>" to solicit review of changes since the previous Candidate Recommendation. The primary changes are to (1) make the AES-128-GCM algorithm mandatory to implement, to address newly publicized chosen-ciphertext attacks against the CBC class of algorithms, (2) add new security considerations related to chosen-ciphertext attacks, timing attacks, CBC block encryption vulnerabilities, and the insecure use of error messages, (3) add a new algorithm for the RSA-OAEP key transport that does not require SHA-1 with the mask generation function, enabling use of various hash MGF combinations.</p>
<p>The XML Security WG is also soliciting review of the Last Call working draft of
"<a href="http://www.w3.org/TR/2012/WD-xmlenc-transform20-20120105/">XML Encryption 1.1 CipherReference Processing using 2.0 Transforms</a>". This specification brings the simplification benefits of the ongoing XML Security 2.0 effort to XML Encryption CipherReference transform processing. Feedback on both of these Last Call drafts is requested by 16 February 2012.</p>
<p>The Working Group also published today First Public Working Drafts
of "<a href="http://www.w3.org/TR/2012/WD-xmlenc-core1-testcases-20120105/">Test Cases for XML Encryption 1.1</a>" and
"<a href="http://www.w3.org/TR/2012/WD-xml-c14n2-testcases-20120105/">Test Cases for Canonical XML 2.0</a>" and encourages community participation in developing further tests and performing testing.
