Abstract

Message Exchange Pattern (MEP) is a challenging problem in the interaction of Web services. However, by means of the non-formal descriptions, such as in SOAP and WSDL, it is impossible to conduct precise definition of MEPs, thus leading to potential ambiguities that can degrade the interoperability of Web services. Moreover, it is difficult to enact the MEPs automatically, which means the Web services infrastructure has to hard-code the support for various MEPs and it is also difficult to be extended. In this paper, we propose an automatic enactment of MEPs for Web services. The enactment consists of two parts. The first part is the formal description method for MEPs, which is used to define MEP accurately with no ambiguities. The second part is the automatic enactment framework, which will automatically enact a new MEP through a MEP process machine that is generated according to the MEP definition. New MEPs would become easy to be engaged in Web services.
