| 摘要: |
| 模型转换是模型驱动体系结构的核心技术之一.在一个复杂的模型驱动的开发过程中,可能同时使用多种转换语言及相应的工具实现转换程序.这一方面增加了开发人员的学习负担,也会导致各种兼容性问题的出现.提出一种语义可配置的模型转换技术,通过重新定义转换语言的语义,允许开发人员使用一种转换语言解决不同的转换问题.首先,总结出一组常见的转换原语;然后,利用一种基于OCL 的脚本语言TSS 来描述转换语言的语义;最后,对该方法的完全性、表达能力和复杂度进行了讨论,并通过一组案例对该方法进行了验证. |

| Abstract: |
| Model transformation is a vital technique of MDA. In a complex model-driven development process, it is most likely capapble of employing multiple transformation languages, along with their corresponding tools, to develop a set of model transformations. This increases the learning costs, and also leads to some compatibility problems. The paper proposes a technique of semantics-configurable model transformation, which enables developers to solve different problems using one transformation language, by redefining the semantics of the language. First, a set of common primitive actions are proposed. Then, TSS, an OCL-based scripting language, is employed to specify the logic of a primitive action. Finally, the paper discusses the completeness, expressiveness, and complexity of this approach, and evaluates the approach with some case studies. |
