Architecture Centric System Design for Supporting Reconfiguration of Service Oriented Systems

Service-oriented system development is becoming a prominent software development paradigm. A lot of work has been focused on semantic Web and service integration. However, less work has been invested in how to support reconfiguration of the service oriented systems when they evolve dynamically. This paper applies architecture centric system design approach to design of the e-business systems and combines semantic Web technology with e-business modeling to semantically describe service oriented e-business model. Component specifications are attached with semantic information, and component dependencies are semantically defined. The e-business model facilitates semantics based service discovering and service composing, thus the e-business reconfiguration guided by business architecture can be conducted automatically when services are removed or modified.
