2008-04-15: The Rule Interchange Format (RIF) Working Group published three drafts today:
These drafts help solidify the "pure logic rules" branch of RIF, which is distinct from the "production rules" branch (on which a Working Draft is expected within the next 6 months). Both branches share "RIF Core" (also expected within the next 6 months). The Framework document (FLD) specifies how the various logic dialects relate, while the Basic Logic Dialect (BLD) provides an interlingua for rule languages providing approximately "Horn" expressivity. The third document specifies how BLD can be logically combined with RDF and OWL. Learn more about the Semantic Web Activity. (Permalink)

2008-04-15: The Ubiquitous Web Applications Working Group has published a Working Draft of Delivery Context Ontology. The Delivery Context Ontology provides a formal model of the characteristics of the environment in which devices interact with the Web or other services. The delivery context is an important source of information that can be used to adapt materials to make them useable on a wide range of different devices with different capabilities. The delivery context includes the characteristics of the device, the software used to access the service and the network providing the connection among others. This document describes the ontology (using OWL) and gives details of each property that it contains. Learn more about the Ubiquitous Web Applications Activity. (Permalink)
2008-04-15: The Internationalization Core Working Group has published a Working Draft of Web Services Internationalization (WS-I18N). This document describes enhancements to SOAP messaging to provide internationalized and localized operations using locale and international preferences. These mechanisms can be used to accommodate a wide variety of development models for international usage. Learn more about the Internationalization Activity. (Permalink)
2008-04-15: The Mobile Web Initiative Device Description Working Group has published a Group Note of Device Description Repository Core Vocabulary. This document identifies properties that are considered essential for adaptation of content in the Mobile Web. Its intended use is to define a baseline Vocabulary for Device Description Repository (DDR) implementations. The Vocabulary defined in this document is not intended to represent an exhaustive set of properties for content adaptation. DDR Implementations that require additional properties are free to make use of additional vocabularies. The process of creating a new Vocabulary can be modeled on the process described in this document. Learn more about the Mobile Web Initiative Activity. (Permalink)
2008-04-15: The Uncertainty Reasoning for the World Wide Web Incubator Group published their final report. The document includes a set of use case descriptions that illustrate situations for reasoning under uncertainty; some of the use cases include comprehensive information and details on how uncertainty would help to address issues that cannot be properly addressed with current deterministic approaches. The document also identifies methodologies that may be applied to address the use cases and that show promise as candidate solutions for uncertainty reasoning on the scale of the World Wide Web. 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. (Permalink)
2008-04-15: The Common Web Language Incubator Group published their final report. The goal of the Common Web Language is to allow the exchange of information through the Web and also for enabling computers to process information semantically. CWL allows people to describe contents and meta-data of Web pages written in natural language; the language seeks to lower language barriers and to facilitate the automatic extraction of information from Web pages. 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. (Permalink)
2008-04-14: The Web Application Formats Working Group has published four Working Drafts related to Widgets 1.0: The Widget Landscape (Q1 2008), Packaging and Configuration, Digital Signature, and Requirements; these are the First Public drafts for Digital Signatures and Landscape. Widgets are small client-side Web applications for displaying and updating remote data, that are packaged in a way to allow a single download and installation on a client machine, mobile phone, or mobile Internet device. "Landscape" reviews commonalities and fragmentation across widget user agents and explores how fragmentation currently affects, amongst other things, authoring, security, distribution and deployment, internationalization and the device-independence of widgets. "Packaging" defines a Zip-based packaging format and an XML-based configuration document format for widgets. "Digital Signature" defines a profile of the XML-Signature Syntax and Processing specification to allow a widget resource to be digitally signed. "Requirements" lists the design goals and requirements that specification would need to address in order to standardize various aspects of widgets. Learn more about the Rich Web Client Activity.

2008-04-14: The Mobile Web Best Practices Working Group has published the First Public Working Draft of Content Transformation Guidelines 1.0. This document provides guidance to managers of content transformation proxies and to content providers for how to coordinate when delivering Web content. Content transformation techniques diverge widely on the web, with many non-standard HTTP implications, and no well-understood means either of identifying the presence of such transforming proxies, nor of controlling their actions. This document establishes a framework to allow that to happen. Learn more about the Mobile Web Initiative Activity. (Permalink)
2008-04-14: The Multimodal Interaction Working Group has published an updated Working Draft of Multimodal Architecture and Interfaces (MMI Architecture), which defines a loosely coupled architecture for multimodal user interfaces. The main change in this draft is a more thorough specification of the events sent between the Runtime Framework and the Modality Components, including both schemas for the individual messages and ladder diagrams showing message sequences. The architecture envisioned by the Working Group will provide a general and flexible framework providing interoperability among modality-specific components from different vendors - for example, speech recognition from one vendor and handwriting recognition from another.

2008-04-11: The OWL Working Group published six drafts today related to the OWL 2 Web Ontology Language:
OWL 2 (previously known as OWL 1.1) defines extensions to OWL, which is one of the core standards of the Semantic Web. Semantic Web terms (such as "author" or "title") can be organized into vocabularies (such as "data about publications"). OWL is used to represent the meaning of terms (see, for example, the work of the Health Care and Life Sciences Interest Group) in these vocabularies (or, "ontologies'), and relationships between those terms. Three of the drafts published today (syntax, semantics, and mapping-to-rdf) are the same as their January 2008 counterparts except for the name change. Of the three new drafts: "XML Serialization" specifies a new XML (not RDF/XML) syntax for OWL; "Profiles" specifies subsets (logical fragments) of OWL that target particular application contexts; and the "Primer" provides a unified technical introduction to OWL 2. The Working Group seeks feedback on these drafts and has highlighted particular issues throughout the documents. Learn more about the Semantic Web. (Permalink)
2008-04-10: The XHTML2 Working Group has published the second Last Call Working Draft of XHTML Role Attribute Module. The XHTML Role Attribute defined in this specification allows the author to annotate XML Languages with machine-extractable semantic information about the purpose of an element. Use cases include accessibility, device adaptation, server-side processing, and complex data description. This attribute can be integrated into any markup language based upon XHTML Modularization. Comments are welcome through 10 May. Learn more about the HTML Activity. (Permalink)
2008-04-10: The Web API Working Group has published the Working Draft of Language Bindings for DOM Specifications. This specification defines an Interface Definition Language (IDL) to be used by other specifications that define a Document Object Model (DOM). The document also addresses how interfaces described with this IDL correspond to constructs within ECMAScript and Java execution environments. Learn more about the Rich Web Client Activity.

2008-04-09: W3C is pleased to announce the creation of the Rich Web Application Backplane Incubator Group, sponsored by W3C Members CWI, HP, IBM, and Xerox. The mission of the XG is to explore and refine the architecture of a "Rich Web Application Backplane" -- a set of common building blocks for Web applications. The XG charter states: "[B]enefits to end-user interaction of adopting such common infrastructure will include richer user interaction enabled through simplified approaches to mixing multiple interaction technologies in a single application. The ability to easily share data across multiple components, and to freely intermix AJAX and declarative components, should support a wider range of high function composable UIs." Like all XG's, this group's work is not standards-track. Read more about the Incubator Activity, an initiative to foster development of emerging Web-related technologies. (Permalink)
2008-04-08: The mission of the W3C Health Care and Life Sciences (HCLS) Interest Group is to show how to use Semantic Web technology to answer cross-disciplinary questions in life science that have, until now, been prohibitively difficult to research. Today the HCLS Interest Group published two Working Drafts. The first describes the construction and use of the knowledge base that was used as part of a demonstration of life sciences data integration at the the 2007 World Wide Web Conference in Banff, Canada. The second document explains the process of integrating data with an existing Semantic Web knowledge base. The success of the group continues to draw industry interest. W3C Members are currently reviewing a draft charter that would enable the renewed HCLS Interest Group to develop and support use cases that have clear scientific, business and/or technical value, using Semantic Web technologies in three areas: life science, translational medicine, and health care. We invite all W3C Members to review the draft charter (which is public during the review), and encourage those who are interested in using the Semantic Web to solve knowledge representation and integration on a large scale to join the Interest Group.

2008-04-08: The Mobile Web Initiative Device Description Working Group has published the First Public and Last Call Working Draft of Device Description Repository Simple API. Web content delivered to mobile devices usually benefits from being tailored to take into account a range of factors such as screen size, markup language support and image format support. Such information is stored in "Device Description Repositories" (DDRs). This document describes a simple API for access to DDRs, in order to ease and promote the development of Web content that adapts to its Delivery Context. Comments are welcome through 01 May. Learn more about the Mobile Web Initiative. (Permalink)

2008-04-03: The XML Core Working Group has published the Last Call Working Draft of XML Linking Language (XLink) Version 1.1. This specification defines the XML Linking Language (XLink) Version 1.1, which allows elements to be inserted into XML documents in order to create and describe links between resources. It uses XML syntax to create structures that can describe links similar to the simple unidirectional hyperlinks of today's HTML, as well as more sophisticated links. Comments are welcome through 16 May. Learn more about the Extensible Markup Language (XML) Activity. (Permalink)
2008-04-03: The W3C SWS Testbed Incubator Group published their final report: SWS Challenge Testbed Incubator Methodology Report. This document describes the SWS Testbed XG's Final Report on the best practices for a methodology for evaluating the efficacy of various techniques for mediation, discovery, and composition of Web Services, such techniques including software engineering approaches as well as semantic annotations. These best practices are based upon two years of experience with five workshops and one year of discussion and meetings on this subject by the XG Participants. The publication is part of the Incubator Activity, a forum where W3C Members can innovate and experiment. (Permalink)
2008-04-03: The Web Security Context Working Group has published a Working Draft of Web Security Context: Experience, Indicators, and Trust. 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; on handling errors in security protocols in a way that minimizes the trust decisions left to users, and induces them toward safe behavior where they have to make these decisions; and on data entry interactions that will make it easier for users to enter sensitive data into legitimate sites than to enter them into illegitimate sites. Learn more about the Security Activity. (Permalink)
2008-04-03: The XHTML2 Working Group has published a Working Draft of CURIE Syntax 1.0. The aim of this document is to outline a syntax for expressing URIs in a generic, abbreviated syntax. While it has been produced in conjunction with the XHTML 2 Working Group, it is not specifically targeted at use by XHTML Family Markup Languages. Note that the target audience for this document is Language designers, not the users of those Languages. Learn more about the HTML Activity. (Permalink)
