Last Call: Accessible Rich Internet Applications (WAI-ARIA); Best Practices and Implementation Guide Drafts Also Published

2009-02-24: The Protocols and Formats Working Group published the Last Call Working Draft of Accessible Rich Internet Applications (WAI-ARIA). WAI-ARIA defines a way to make Web content and Web applications more accessible to people with disabilities. It especially helps with dynamic content and advanced user interface controls developed with Ajax, HTML, JavaScript, and related technologies.

The Working Group also published a First Public Working Draft of the WAI-ARIA User Agent Implementation Guide that provides guidance on how browsers and other user agents should expose WAI-ARIA features to platform accessibility APIs. The updated Working Draft of WAI-ARIA Best Practices that was published today describes how Web content developers can develop accessible rich Web applications using WAI-ARIA. These WAI-ARIA documents are described in the WAI-ARIA Overview. Read details in the review announcement, and about the Web Accessibility Initiative (WAI). (Permalink)

XML Security Working Group Releases Eight Working Drafts

2009-02-26: The XML Security Working Group has published a set of eight Working Drafts. The XML Signature 1.1 and XML Encryption 1.1 First Public Working Drafts make changes to the default sets of cryptographic algorithms in both specifications. XML Security Use Cases and Requirements and XML Signature Transform Simplification: Requirements and Design are documents that we expect to help guide the group's work on a future version of the XML Security specifications that might make more radical changes than the 1.1 series of these specifications. The Working Group would like to receive early feedback on these four drafts.

Additionally, the XML Security Derived Keys specification introduces mark-up for key derivation, for use with both XML Signature and XML Encryption. XML Signature Properties defines commonly used signature properties. XML Security Algorithms is a cross-reference for the algorithms and their identifiers used with the XML security specifications, bringing in one place information located in a number of documents. XML Signature Best Practices is a revised Working Draft for Best Practices in using the XML Signature specification. (Permalink)

Last Call: Web Security Context: User Interface Guidelines

2009-02-26: The Web Security Context Working Group has published the second Last Call Working Draft of Web Security Context: User Interface Guidelines. This specification deals with the trust decisions that users must make online, and with ways to support them in making safe and informed decisions where possible. In order to achieve that goal, this specification includes recommendations on the presentation of identity information by Web user agents. It also includes recommendations for handling errors in security protocols. This second Last Call Working Draft incorporates feedback gathered during the first Last Call period, both from the public and from implementers participating in the Working Group. Comments are welcome through 19 March 2009. Learn more about the Security Activity. (Permalink)

Call for Review: Service Modeling Language, Version 1.1 Proposed Recommendation

2009-02-13: The Service Modeling Language Working Group has published the Proposed Recommendations of Service Modeling Language, Version 1.1 and Service Modeling Language Interchange Format Version 1.1. SML extends the coherence-checking mechanisms of W3C XML Schema from individual documents to collections of documents. SML-IF extends the utility of SML by providing mechanisms for gathering together a set of documents whose coherence is guaranteed by an SML schema, which itself is part of the resulting package.

W3C Multimodal Standard Brings Web to More People, More Ways

2009-02-10: As part of ensuring the Web is available to all people on any device, W3C published a new standard today to enable interactions beyond the familiar keyboard and mouse. EMMA, the EMMA: Extensible MultiModal Annotation Markup Language, promotes the development of rich Web applications that can be adapted to more input modes (such as handwriting, natural language, and gestures) and output modes (such as synthesized speech) at lower cost. The document, published by the Multimodal Interaction Working Group, is part of a set of specifications for multimodal systems, and provides details of an XML markup language for containing and annotating the interpretation of user input. Read the press release and testimonials, and learn more about the Multimodal Interaction Activity. (Permalink)

Widgets 1.0: APIs and Events

2009-02-10: The Web Applications Working Group has published the First Public Working Draft of Widgets 1.0: APIs and Events. This specification defines a set of APIs and events for the Widgets 1.0 Family of Specifications that enable baseline functionality for widgets. The APIs and Events defined by this specification defines, amongst other things, the means to:

• access the metadata declared in a widget's configuration document,
• receive events related to changes in the view state of a widget,
• determine the locale under which a widget is currently running,
• be notified of events relating to the widget being updated,
• invoke a widget to open a URL on the system's default browser,
• requests the user's attention in a device independent manner,
• and check if any additional APIs requested via the configuration document's feature element have successfully loaded.

Social Networking Challenges Identified by Industry Leaders in W3C Workshop

2009-02-03: W3C has published a report from the Workshop on the Future of Social Networking. Observations from the fifty-five organizations that participated (and submitted 72 position papers) include:

• By enabling users to share profiles and data across networks, social networking sites can grow further and open possibilities for a decentralized architecture for the Social Web.
• Contextual information, especially for mobile device users, can significantly enrich the social networking user experience.
• Many users remain unaware of the impact of social networking on their privacy.

The report highlights the need for an interoperable distributed social Web framework and suggests concrete next steps for W3C. W3C now welcomes interested parties to contribute to public discussion.

Last Call: W3C XML Schema Definition Language (XSD) 1.1

2009-02-02: The XML Schema Working Group has published Last Call Working Drafts of W3C XML Schema Definition Language (XSD) 1.1 Part 1: Structures and Part 2: Datatypes. This former specifies the XML Schema Definition Language, which offers facilities for describing the structure and constraining the contents of XML documents, including those which exploit the XML Namespace facility. The schema language, which is itself represented in an XML vocabulary and uses namespaces, substantially reconstructs and considerably extends the capabilities found in XML document type definitions (DTDs). The latter defines facilities for defining datatypes to be used in XML Schemas as well as other XML specifications. The datatype language, which is itself represented in XML, provides a superset of the capabilities found in XML document type definitions (DTDs) for specifying datatypes on elements and attributes. Comments are welcome through 20 February. Learn more about the Extensible Markup Language (XML) Activity. (Permalink)

Working Draft: WebCGM 2.1

2009-02-02: The WebCGM Working Group has published a Working Draft 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. First published (1.0) in 1999, WebCGM unifies potentially diverse approaches to CGM utilization in Web document applications. It therefore represents a significant interoperability agreement amongst major users and implementers of the ISO CGM standard. Learn more about the Graphics Activity. (Permalink)

XML Base (Second Edition) Is a W3C Recommendation

2009-01-28: The XML Core Working Group has published the W3C Recommendation of XML Base (Second Edition). This document describes a mechanism for providing base URI services to XLink, but as a modular specification so that other XML applications benefiting from additional control over relative URIs but not built upon XLink can also make use of it. The syntax consists of a single XML attribute named xml:base. The functionality is similar to the base element in HTML. This document is part of W3C's ongoing work to maintain the core XML technologies. Learn more about the Extensible Markup Language (XML) Activity. (Permalink)
