Coordinating Web Services Activities with WS-Coordination, WS-AtomicTransaction, and WS-BusinessActivity. Luis Felipe Cabrera George Copeland Jim Johnson David Langworthy Microsoft Corporation January 28, 2004 Summary: Understand how the new WS-Coordination specification relates to the WS-AtomicTransaction and WS-BusinessActivity specifications.
These specifications collectively provide the necessary mechanisms to create activities, join in activities, and reach common agreement on the outcome of joint operations across distributed systems. (22 printed pages) WS-Coordination. WS-Coordination is a Web Services specification developed by BEA Systems, IBM, and Microsoft and accepted by OASIS Web Services Transaction TC in its 1.2 version.
It describes an extensible framework for providing protocols that coordinate the actions of distributed applications. Such coordination protocols are used to support a number of applications, including those that need to reach consistent agreement on the outcome of distributed transactions. The framework defined in this specification enables an application service to create a context needed to propagate an activity to other services and to register for coordination protocols. The framework enables existing transaction processing, workflow, and other systems for coordination to hide their proprietary protocols and to operate in a heterogeneous environment. Additionally WS-Coordination describes a definition of the structure of context and the requirements for propagating context between cooperating services.
