一种结合MDA的高阶模型转换方法

Method of higher-order model transformation combined with MDA

模型转换是MDA的关键技术,也是MDA的研究热点。目前,不同的MDA开发平台都有一套相对独立的开发技术和转换框架,这使平台之间缺乏兼容性,模型转换代码重用困难。究其原因是缺少一种与具体转换语言相对应,且与平台无关的转换规则模型。为了解决以上问题,将高阶模型转换的思想与模型驱动软件开发相结合,提出了一种构造模型转换规则的高阶转换元模型,并以ATL语言为例展示了高阶转换元模型的使用方法;最后通过一个实例验证了该方法的可行性和可用性。该方法提高了模型转换语言的抽象层次,降低了模型转换语言的重用难度,在一定程度上解决了模型转换技术不兼容的问题。

Model transformations are the core and research focus of MDA.Nowadays,the MDA development platforms have a set of relatively independent development techniques and transformation frameworks,which causes incompatibility between different platforms and difficulty in reuse of model transformation code.The reason lays on the lack of a platform-independent model of transformation rules corresponding to specific transformation language.To solve these shortcomings,this paper combined higher-order model transformation with model-driven software development,and proposed a kind of general higher-order transformation metamodel which described the model transformation.Furthermore the ATL language,for example,showed the use of higher-order transformation metamodel.At last,it provided a study case to verify its feasibility and availability.The approach improves the Abstraction layer of model transformations,reduces the difficulty of the reuse of model transformation language,and solves the incompatible problem of model transformation technology in a way.
