A formalizing hybrid model transformation approach for collaborative system

Model transformation plays an important role in current MDD (Model Driven Development). Combined with direct model manipulation, relational algebra and template theory, this paper presents a formalizing hybrid model transformation for the design in universal collaborative system. Furthermore, it implements an extendible prototype system based on MDA paradigm called CSCWMDA. CSCWMDA specifies a model driven process that takes UML models and generates collaborative system code by hybrid model transformation. Finally, a case study of Cooperative Authoring System illustrates our approach demonstrating the hybrid MDE process. This approach removes the heterogeneity of model transformation to some extent, and at the same time it is simple and well regulated.
