A Route-Based Composition Language for Service Cooperation

Service-oriented programming model provides an effective way to integrate different applications across distributed, heterogeneous, dynamic environment which is common in e-business. Web service, with WSDL, SOAP and related protocols, is such an industrial effort to address the interoperation of different systems. Service composition is to combine such services, which distributed among different organizations, to new complex and value-added service while preserving the autonomy of the old ones. In this paper, we identify some common patterns and scenarios of service composition and then propose a general framework for dynamic service publish, discovery and life management which is the basis of service composition. By extending and enhancing web service definition, a route-based composition language xSCL is proposed to solve problems that impede service reuse.
