Web Services Activity

Groups · News · Documents · Wiki and tools · Technical discussion · Events

The World Wide Web is more and more used for application to application communication. The programmatic interfaces made available are referred to as Web services.

The goal of the Web Services Activity is to develop a set of technologies in order to lead Web services to their full potential. The Web Services Activity Statement explains the W3C's work on this topic in more detail.

• 2011-04-28: The Web Services Resource Access Working Group published seven Candidate Recommendations: Enumeration (WS-Enumeration), Event Descriptions (WS-EventDescriptions), Eventing (WS-Eventing), Fragment (WS-Fragment), Metadata Exchange (WS-MetadataExchange), SOAP Assertions (WS-SOAPAssertions), and Transfer (WS-Transfer). The review period ends 20 May 2011.
• 2009-09-24: The Web Services Resource Access Working Group published five Working Drafts: WS-Transfer, WS-Resource Transfer, WS-Enumeration, WS-Metadata Exchange and WS-Eventing.
• 2009-07-10: The XML Schema Patterns for Databinding Working Group, the Web Services Choreography Working Group and the XML Protocol Working Group were closed.
• 2009-06-04: The SOAP-JMS Binding Working Group published SOAP over Java Message Service 1.0 as a Candidate Recommendation. The review period ends 31 August 2009
• 2009-03-17: The Web Services Resource Access Working Group published five Working Drafts: WS-Transfer, WS-Resource Transfer, WS-Enumeration, WS-Metadata Exchange and WS-Eventing.
• 2008-11-21: The SOAP-JMS Binding Working Group published SOAP over Java Message Service 1.0 as a Last Call Working Draft. The review period ends 13 January 2009
• 2008-11-07: The Web Services Resource Access Working Group has been created. See its charter. The mission of the WS Resource Access WG is to produce W3C Recommendations for a set of Web Services specifications by refining the WS-Transfer, WS-ResourceTransfer, WS-Enumeration, WS-MetadataExchange and WS-Eventing Member Submissions, addressing existing issues in those specifications, implementation experience and interoperability feedback from implementers and considering composition with other Web services standards.
• 2008-07-23: The SOAP-JMS Binding Working Group published SOAP over Java Message Service 1.0 as a First Public Working Draft.
• 2008-04-11: The proposed charter for the SOAP-JMS Binding Working Group has been created. The mission of the SOAP-JMS Binding Working Group is to produce a W3C Recommendation for how SOAP should bind to a transport that supports the Java™ Message Service (JMS) api by refining the "SOAP over Java™ Message Service 1.0" Member Submission. In the case of SOAP 1.2 this binding must use the SOAP Protocol Binding Framework defined by the XML Protocol Working Group.
• 2008-03-28: The XML Schema Patterns for Databinding Working Group published Basic XML Schema Patterns for Databinding Version 1.0 as a Last Call Working Draft. The review period ends 30 April 2008
• 2007-12-26: The proposed charter for the Web Services Core Working Group will not be approved by the Director, due to its incompatibilities with the W3C Patent Policy. Maintenance of existing W3C Recommendations in Web Services will be accomplished through ad-hoc Groups.
• 2007-12-21: The Efficient XML Interchange (EXI) Working Group has published three documents: First Public Working Drafts of EXI Best Practices and EXI Primer, as well as a Working Draft of EXI Format 1.0. EXI is a very compact representation for the Extensible Markup Language (XML) Information Set that is intended to simultaneously optimize performance and the utilization of computational resources. Using a relatively simple algorithm, which is amenable to fast and compact implementation, and a small set of data types, it reliably produces efficient encodings of XML event streams. The primer and best practices documents complement the format specification. The best practices document also presents information suitable for the general reader interested in EXI's intended role in the expanding Web.
