Model-driven Web service engineering

 

Description

The development of composite Web services is still not as simple as the original vision indicated. Currently, the designer of a composite service needs to consider many different design aspects at once. In this project, we propose a modeling methodology based on UML which separates between the four concerns of structure, transactions, workflow, and security, each of which can be modeled by different experts. We have developed a proof-of-concept tool based on Eclipse that is able to extract information from the model and transform it into a computer-readable format and ultimately generate a set of Web service documents (e.g., BPEL, WS-Policy, WS-CDL etc.)
