Facilitating dynamic service compositions by adaptable service connectors

Dynamic changes of services and requirements require service connection relationships adaptable in service compositions. This paper presents an adaptable service connector model and related language and tools. The model presents service connection relationships as an explicit component with which service connections can be reconfigured and changes of services involved in the interaction can be handled; this makes the service connection relationships more adaptive. With the language and tools supporting the model, services can be dynamically chained, which make service-oriented applications adapt to volatile business requirements and dynamic changeable services. The related case study and evaluation are also presented in this paper.
