Research on DSL-based composition language in service-oriented architecture

Enterprise Service Bus is the request and convergence point of all the services for the large-scale distributed applications. How to compose the service in the dynamic and open network environment is a difficult problem. This paper proposes a service-oriented DSL composition language, which provides Web service semantic description of the composition process. The language uses top-down composition approach and considers the matching of heterogeneous messages. It can be properly resolved the composition process granularity control and heterogeneous messages matching. It has some application value for loosely coupled, cross-platform, heterogeneous environments composition and integration of Web service such as e-commerce, e-government, and workflow based on Web services and so on.
