W3C Renews Web Services Activity, Expanding Work Semantic Annotations for WSDL Working Group Launched.http://www.w3.org/ -- The World Wide Web Consortium (W3C (World Wide Web Consortium, www.w3.org) An international industry consortium founded in 1994 by Tim Berners-Lee to develop standards for the Web. It is hosted in the U.S. by the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT (www.csail.mit.edu/index.php). ) reinforces its commitment to building the foundations of Web Services by renewing its Web Services Activity. W3C continues work on SOAP, Web Services Description Language “WSDL” redirects here. For other uses, see WSDL (disambiguation). The Web Services Description Language (WSDL, pronounced 'wiz-dəl' or spelled out, 'W-S-D-L') is an XML-based language that provides a model for describing Web services. (WSDL (Web Services Description Language) An XML-based language for defining Web services. Developed by Microsoft and IBM, WSDL describes the protocols and formats used by the service. ), and Addressing specifications and features a new group chartered to enhance Web services descriptions with semantics. Augmenting Web services with Semantic Web technology makes it easier to automate the composition and discovery of Web Services. Semantics Enrich Web Service Descriptions WSDL is used to describe the interface of a Web service, its inputs and outputs. WSDL alone does not provide enough information to determine automatically whether the interfaces of two arbitrary Web services are compatible. Semantic descriptions make it easier to identify automatically services that have compatible inputs and outputs. Thus, given a description of a service for finding books and a description of a service for purchasing them, both equipped with semantics, it becomes much easier to combine the two into a more useful composite. For the same reasons, machine-readable semantic descriptions facilitate the discovery of pertinent Web services. Hooks in WSDL 2.0 WSDL 2.0 includes the hooks to allow the specification of semantic descriptions. W3C has chartered the Semantic Annotations for Web Services Description Language (SAWSDL) Working Group to develop an annotation mechanism that takes advantage of those hooks. "There are multiple communities around Semantic Web Services Semantic Web Services are self-contained, self-describing, semantically marked-up software resources that can be published, discovered, composed and executed across the Web in a task driven semi-automatic way. ," explains Jacek Kopecky, chair of the Semantic Annotations for WSDL Working Group and representative from DERI Innsbruck. "W3C is bringing them together under its consensus-driven process to ensure that the rich and varied expertise can be distilled and put to work in a standard solution for Web automation." The Semantic Annotations for WSDL Working Group will also provide a mapping of the new properties into a Resource Description Framework (World-Wide Web, specification, data) Resource Description Framework - (RDF) A specification being developed in 2000 by the W3C as a foundation for processing meta-data regarding resources on the Internet, including the World-Wide Web. (RDF (Resource Description Framework) A recommendation from the W3C for creating meta-data structures that define data on the Web. RDF is designed to provide a method for classification of data on Web sites in order to improve searching and navigation (see Semantic Web). ) form compatible with the existing RDF mapping for WSDL. Industry and Research Communities to foster Semantic Web and Web Services Convergence More than 400 researchers and developers participate in the continuing Semantic Web Services Interest Group (SWS IG), a public forum created in 2003 to discuss Web Services topics oriented towards integration of the Semantic Web and Web Services. Their feedback and observations from both research and business initiatives are expected to help the new Working Group ground its work in real world experience. In 2005, W3C held the Semantic Web Services workshop to gather information about potential standardization work on Semantics in Web Services. The launch of the SAWSDL Working Group is supported by EC's IST programme WS2 project. About the World Wide Web Consortium (W3C) The World Wide Web Consortium (W3C) is an international consortium where Member organizations, a full-time staff, and the public work together to develop Web standards. W3C primarily pursues its mission through the creation of Web standards and guidelines designed to ensure long-term growth for the Web. Over 400 organizations are Members of the Consortium. W3C is jointly run by the MIT Computer Science and Artificial Intelligence Laboratory  It has been suggested that and be merged into this article or section. (MIT MIT - Massachusetts Institute of Technology CSAIL CSAIL Computer Science & Artificial Intelligence Laboratory (MIT)CSAIL Computer Science and Artificial Intelligence Lab ) in the USA, the European Research Consortium for Informatics and Mathematics (ERCIM ERCIM - European Research Consortium on Informatics and Mathematics. An association of European research organisations promoting cooperative research on key issues in Information Technology. ) headquartered in France, Keio University in Japan, and has additional Offices worldwide.
