W3C OWL 2 Standard Facilitates Information Management and Integration

27 October 2009 | Archive

Today W3C announces a new version of a standard for representing knowledge on the Web. OWL 2, part of W3C's Semantic Web toolkit, allows people to capture their knowledge about a particular domain (say, energy or medicine) and then use tools to manage information, search through it, and learn more from it. As an open standard based on Web technology, OWL 2 lowers the cost of merging knowledge from multiple domains. More than a dozen implementations of OWL 2 are already available. The standard consists of 13 documents, of which 4 are instructional. Read the press release , read the testimonials, and learn more about the Semantic Web.

Incubator Group Report: Rich Web Application Backplane

27 October 2009 | Archive

The Rich Web Application Backplane Incubator Group (XG) published their final report today. The report describes two areas of work undertaken by the XG; authoring patterns helpful in supporting high-function web applications in managing client-side data and user interaction control. In addition, a range of methods are considered for implementing such patterns in current browsers without requiring plug-ins or extensions using javascript-based markup behaviors. The Backplane XG recommends that a workshop be organized bringing together interested parties with an aim to creating a Working Group to define a standardized architecture and API for XML and HTML interaction formats implemented in Javascript. 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.

SML XLink Reference Scheme Note Published

23 October 2009 | Archive

The Service Modeling Language Working Group has published a Group Note of The SML XLink Reference Scheme. The Service Modeling Language [SML] specification extends the Extensible Mark-up Language and XML Schema with a mechanism for incorporating into XML documents references to other documents or document fragments. The SML specification does not mandate the use of any specific reference scheme, and provides an extensibility mechanism for defining new reference schemes. This note illustrates how the extensibility mechanism can be used to define an SML reference scheme based on XLink links. Learn more about the Extensible Markup Language (XML) Activity.

Three Health Care and Life Science Interest Group Notes Published

23 October 2009 | Archive

The Semantic Web Health Care and Life Sciences Interest Group published three Interest Group notes produced by the Scientific Discourse Task Force:

These notes describe how one can use the Semantic Web to express and integrate scientific data from different domains and from heterogeneous services. It is hoped that they will inspire further contributions to the ongoing work of the Health Care and Life Sciences Interest Group and its Scientific Discourse Task Force, as well as inspire those in other domains to exploit the Semantic Web. On a related topic, the Interest Group holds a Workshop on Scientific Discourse at ISWC 2009 on Monday, 26 October. Learn more about the Semantic Web.

W3C Launches MashSSL Incubator Group

22 October 2009 | Archive

W3C is pleased to announce the creation of the MashSSL Incubator Group, whose mission is to create an open security protocol to solve a fundamental Internet security problem. Specifically, when two web applications communicate through a potentially untrusted user they do not have any standard way of mutually authenticating each other and establishing a trusted channel. The group seeks to create an open, secure standard for solving this problem. The following W3C Members have sponsored the charter for this group: DigiCert, Venafi and VeriSign. Read more about the Incubator Activity, an initiative to foster development of emerging Web-related technologies. Incubator Activity work is not on the W3C standards track.

Six SPARQL 1.1 First Drafts Published

Two Security First Drafts Published: XML Signature Syntax and Processing Version 2.0; Canonical XML Version 2.0

22 October 2009 | Archive

The XML Security Working Group has published two First Public Working Drafts: XML Signature Syntax and Processing Version 2.0 and Canonical XML Version 2.0. The former provides integrity, message authentication, and/or signer authentication services for data of any type, whether located within the XML that includes the signature or elsewhere. XML Signature 2.0 includes a new transform model designed to address requirements including performance, simplicity and streamability. This model is significantly different than in XML Signature 1.x (see Section 10: "Differences from 1.x version"). XML Signature 2.0 is designed to be backward compatible, however, enabling the XML Signature 1.x model to be used where necessary. Canonical XML Version 2.0 is a major rewrite of Canonical XML Version 1.1 to address issues around performance, streaming, hardware implementation, robustness, minimizing attack surface, determining what is signed and more. It also incorporates an update to Exclusive Canonicalization, effectively a 2.0 version, as well. Learn more about the W3C Security Activity.
