Abstract: This paper introduces a new technique to dynamically compose Web Services in a decentralized manner. Many of the shortcomings of current Web Service composition mechanisms stem from the difficulty of defining, modularizing and managing non-functional concerns and context-sensitive behaviours. Contextual Aspect-Sensitive Services (CASS) is a distributed aspect platform that targets the encapsulation of coordination, activity lifecycle and context propagation concerns in service-oriented environments. CASS enables crosscutting and context-sensitive concerns to be factored out of the service implementations and modularized into separate units of encapsulation. CASS does not require a centralized orchestration engine to coordinate the message exchanges. Coordination logic is woven directly at the level of the message processing engine. The CASS composition definition language offers a powerful alternative to static and centralized business process definition languages such as BPEL4WS.
