Web Services Activity Statement

Web services provide a standard means of interoperating between different software applications, running on a variety of platforms and/or frameworks. Web services are characterized by their great interoperability and extensibility, as well as their machine-processable descriptions thanks to the use of XML. They can be combined in a loosely coupled way in order to achieve complex operations. Programs providing simple services can interact with each other in order to deliver sophisticated added-value services.

The W3C Web Services Activity is designing the infrastructure, defining the architecture and creating the core technologies for Web services. The SOAP 1.2 XML-based messaging framework became a W3C Recommendation in June 2003 and the SOAP Message Transmission Optimization Mechanism (MTOM) in January 2005.

Highlights Since the Previous Advisory Committee Meeting

Since the last Advisory Committee Meeting, eight new W3C Recommendations were published.

The Web Services Resource Access Working Group advanced seven documents to Recommendations:

The SOAP-JMS Binding Working Group advanced one document to Recommendation:

W3C organized a workshop on Data and Services Integration . It was held October 20-21 2011 in Bedford, MA, hosted by MITRE. See the Workshop Report.

Upcoming Activity Highlights

Most Working Groups are now in "maintenance mode", ie: lower activity, but monitoring issue reports.

At this time, no new Working Groups are planned within this Activity, but new work based on the experience gathered during the development of Web Services is likely, though it may happen in another Activity.
