With the requirement for complex Web Services steadily increasing, there is a growing interest for reusing basic, existing Web Services to composite new ones. We present a composite Web Services development approach driven by model driven architecture (MDA): using UML(Unified Modeling Language) class diagram to model structure PIM(Plateform Independent Platform) and UML activity diagram to model behavior PIM, then by model transformation converting the PIMs to specific Web Services specification platforms and execution platform to get the corresponding PSMs (platform specific models). The main contributions of this paper are the all-around solution to Web Services composition development and the transformation rules for structure and behavior model of Web Services between PIMs and PSMs.
