A Weaving Framework for Model Transformation

Model transformations are the core and research focus of MDA(model driven architecture). Nowadays, there are many model transformation approaches and tools, and the heterogeneity of them causes that the model transformation code can’t be reused easily and the cost of studying and using model transformation increases. To eliminate these shortcomings, inspired by model weaving technique, this paper proposes a QVT(model query/view/transformation)-based model transformation weaving framework named QMTW(QVT-based model transformation weaving framework). The conception, semantics, metamodel and syntax of QMTW added with a mapping from itself to the QVT Relation language are subscribed. A study case is provided to show how developers can use and take advantage of QMTW. The approach promotes the abstraction layer of model transformations, unites other model transformation languages, and supports QVT specification. So it eliminates the heterogeneity of model transformation partly. It is simple, specification-based and extensible.
