A service composabilty model to support dynamic cooperation of cross-enterprise services

Abstract

With the development of web services related technologies, more and more enterprises adopt web services to encapsulate their business systems to be published on Internet. Due to the different semantic of the web services, it brings much difficulty to implement the dynamic cooperation of the cross-enterprise services efficiently. This paper introduces a service composability model to support the dynamic cooperation of cross-enterprise services by utilizing the semantic rules of the internal composability. The WSDL descriptions of the web services are extended with semantic capability, which enable the cross-enterprise services to be composed and cooperated automatically according to the synthetic comparison of the semantic features. Furthermore, a policy driven negotiation process is also proposed to enable the cooperation of cross-enterprise services to achieve win-win.
