2. Call for Participation: W3C Workshop on Frameworks for Semantics in Web Services

Position papers are due 22 April for the W3C Workshop on Frameworks for Semantics in Web Services to be held 9-10 June in Innsbruck, Austria. Participants will discuss possible future W3C work on a comprehensive and expressive framework for describing all aspects of Web services. The workshop's goal is to envision more powerful tools and fuller automation using Semantic Web technologies such as RDF and OWL.

3. xml:id Is a W3C Candidate Recommendation

W3C is pleased to announce the advancement of xml:id Version 1.0 to Candidate Recommendation. The specification introduces a predefined attribute name that can always be treated as an ID and hence can always be recognized. Comments are invited through 10 March.

4. Last Call: SMIL 2.1

The SYMM Working Group has released the First Public Working Draft of Synchronized Multimedia Integration Language (SMIL 2.1) as a Last Call Working Draft. Comments are welcome through 25 February. SMIL (pronounced "smile") puts animation on a time line, allows composition of multiple animations, and describes animation elements for any XML-based host language. Version 2.1 extends SMIL 2.0 and supports enhanced interactive multimedia presentations, reuse of SMIL syntax and semantics, and new mobile profiles.

5. Working Group Note: Extending XLink 1.0

The XML Core Working Group has released Extending XLink 1.0 as a Working Group Note. The document describes changes that could be incorporated into an XLink Version 1.1 specification to address usability, dependence on annotations provided by external grammars, and interoperability. The Working Group plans no updates to this Note.

6. W3C Supports the URI Standard and IRI Proposed Standard

W3C is pleased to announce its support for two publications that are important for Web addressing and increase the international reach of the Web. The documents are coordinated efforts of the Internet Engineering Task Force (IETF) and W3C.

Uniform Resource Identifier (URI): Generic Syntax (RFC 3986, STD 66) was written by Tim Berners-Lee (W3C), Roy Fielding (Day Software) and Larry Masinter (Adobe) with involvement of the W3C Technical Architecture Group (TAG). Simple text strings that refer to Internet resources, URIs may refer to documents, resources, to people, and indirectly to anything. URIs are the most fundamental component of the Web.

Internationalized Resource Identifiers (IRIs) (RFC 3987) was written by Martin Dürst (W3C) and Michel Suignard (Microsoft) with involvement of the W3C Internationalization Working Group. Lifting the limitation of URIs to a subset of US-ASCII, IRIs allow characters in the Universal Character Set (Unicode/ISO 10646). Content developers and users can now identify resources in their own languages.

7. W3C Recommendations Enhance SOAP Performance

The World Wide Web Consortium released three W3C Recommendations to improve Web services performance by standardizing the transmission of large binary data. "Web services have just become faster and more usable," said Yves Lafon (W3C). Using an XML Schema datatype, XML-binary Optimized Packaging (XOP) allows efficient serialization of XML element content.

Using a XOP-based selective encoding, the SOAP Message Transmission Optimization Mechanism optimizes hop-by-hop exchanges between SOAP nodes.

The Resource Representation SOAP Header Block allows applications to carry a representation of a resource in a SOAP message.
