The World Wide Web Consortium (W3C) has released Web Services Addressing - Core and its SOAP Binding as W3C Recommendations.

The Core properties allow uniform addressing of Web services and messages, independent of the underlying transport, by providing a transport-neutral mechanism for addressing objects in Web services applications built on top of URIs.

This new method is called an endpoint reference, or EPR. EPRs are designed to solve problems posed by: dynamic generation and customisation of service endpoint descriptions, such as those created for a session id or customer id; referencing and description of specific service instances that are created as the result of stateful interactions; and flexible and dynamic exchange of endpoint information in tightly coupled environments where communicating parties share a set of common assumptions about specific policies or protocols that are used during the interaction.

'Web Services Addressing 1.0 provides a mechanism to developers on how to address objects for Web services applications,' said Philippe Le Hégaret, W3C Architecture Domain leader. 'It extends the capabilities of Web services by enabling asynchronous message exchanges, and allowing more than two services to interact.'
