A Dynamic Reconfigurable Web Service Composition Framework Using Reo Coordination Language

Web services are self-contained, modular units of application logic which provide business functionality to other applications via Internet connections. Several models have been used to compose Web services which are mainly served at specification level and provide static data dependent coordination processes. Hence they can not support reconfigurable dynamic coordination processes in which participant Web services and the coordination process itself will not be known explicitly prior to execution and would be determined dynamically at run time. In this paper we present a framework to coordinate Web services using Reo coordination language. Reo is a channel-based exogenous coordination language which has a formal basis and supports loose coupling, distribution, dynamic reconfiguration and mobility. Given that Web services are inherently loosely coupled and primarily built independently, the channel-based structure of Reo and its reconfigurability will provide a reconfigurable coordina...
