摘　　要：模型转换是MDA(modeldrivenarchitecture)的核心技术之一,也是目前MDA研究的热点.目前,MDA范畴内存在多种模型转换方法和工具,它们之间的异构性造成了模型转换代码重用的困难,并使学习和使用模型转换方法的成本增加.受到模型编织技术的启发,提出了一种基于QVT(modelquery/view/transformation)规范的模型转换编织框架QMTW(QVT-basedmodeltransformationweavingframework)来解决以上缺点.展示了模型转换编织的概念、语义、元模型和语法,以及到目标语言的转换定义,并以一个具体实例说明了本框架的使用方法和优点.QMTW提高了模型转换的抽象层次,统一了多种模型转换语言,并支持OMG最新的模型转换规范,在一定程度上消除了模型转换技术的异构性,同时具有简单、规范、扩展性强3个优点.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.
