A MDE Based Approach for Bridging Formal Models

Different formal methods have presented plenty of formal models for system specification and proof. Hence the problem of bridging these formal models rises. MDE is a new paradigm in software engineering, which  implements software by (meta-)modeling and model transforming. In this paper, we provide a MDE based approach for  bridging heterogeneous formal models: Firstly, the heterogeneous formal models are introduced into MDE as domain specific languages by metamodeling. Then, transformation rules are built for semantics mapping. At last, model-text syntax rules are developed, so as to map models to programs. Our approach could be applied on formal models in both graphical style and grammatical style. A case study of bridging MARTE to LOTOS is also illustrated showing the validity and practicability of our approach.
