摘　　要：模型驱动架构(MDA)是继CORBA,UML之后由OMG推出的重要的软件开发方法学.MDA的核心是模型转换,模型转换语言又是实施模型转换的关键.本文从MOF元模型的角度首先对OCL进行动态特性的扩展,使其具备表达动态行为语义的能力;然后通过扩展相关关键字,定义了一个完整的模型转换程序框架;并提出创建中间转换对象实现了模型转换的可追溯性以及源模型和目标模型转换的同步性.Model-driven architecture（MDA） is a new and very important software development methodology launched by OMG following CORBA and UML.The pivotal problem of MDA is model transformation,and moreover,model transformation language is the key to the implementation of model transformation.This paper,from the perspective of metal model MOF,first,the expansion of dynamic function is made to have OCL the ability to express dynamic behavior semantics;then,through the expansion of keywords concerned,a complete framework of model transformation is defined.The middle conversion object technique is also proposed to make model transformation traceable and maintain the synchronization of source model and target model.
