Three W3C Workshops in early 2005: Rules Languages, Frameworks for Semantics, XML Schema
W3C Workshop on Rule Languages for Interoperability,
Washington, D.C., USA, 27-28 April 2005
Rule languages and rule systems are widely used in applications ranging from database integration, service provisioning, and business process management to loan underwriting, privacy policies and Web services composition. General purpose rule languages remain relatively non standardized, however, and rule systems from different suppliers are rarely interoperable. More recently, RDF and OWL semantic Web languages are beginning to support data/knowledge sharing on the same scale and with considerable flexibility. Many consider that the next fundamental piece of the Semantic Web architecture is a standardized language for sharing rules.
W3C Workshop on Frameworks for Semantics in Web Services,
Innsbruck, Austria, 9-10 June 2005
Web Services standards make up an integrated technology stack that Web applications developers can rely on to ensure interoperability. The initial emphasis of W3C's work has been on well-defined messaging interfaces and protocols, and registries in which services can be advertised. In addition, from the beginning, research has been conducted towards a broad range of challenges in this area, such as managing service lifecycles and resources; providing richer characterizations of processes, capabilities, and constraints; and composing a service from several other services. This workshop aims at gathering experience on applications and architectures that provide semantics for Web services, and at discussing various approaches for integration into the mainstream of Web services technologies, as well as the strategy and sequencing that could be put in place to accomplish this goal. This workshop is organized as part of the Web Services and Semantics (WS2) project, funded by the European Commission's IST FP6 Programme.
W3C Workshop on XML Schema 1.0 User Experiences,
June 21-22, 2005 - Redwood Shores, CA, USA
XML Schema 1.0 has been widely adopted by vendors and as a foundation for other specifications in the Web Services area, in XML query systems, and elsewhere.This workshop will gather concrete reports of user experience with XML Schema 1.0, and examine the full range of usability, implementation, and interoperability problems around the specification and its test suite. Topics of discusson include, but are not limited to, the use of XML Schema in vocabulary design, Web Services description and toolkits, XHTML, XML Query, and XML Schema editors.
