摘　　要：大粒度的模型转换是模型驱动软件开发场景下的重要技术需求,仅通过定义通用模型转换语言不足以满足这一需求,其中一个原因是通用模型转换语言工作在特定建模语言的元模型层次而非一般设计意图层次上.文中提出一种模式语义链(PSL)元建模方法.通过重型扩展统一建模语言(UML)元模型以直接形式化描述可表达一般设计意图的模式,并应用UML动作语义和元模型继承实现模式自动生成及转换.该方法为实现一般设计意图层次上的大粒度模型转换提供了有效支持.The coarse-grained model transformation is an important technical requirement on the Model-Driven Software Development (MDSD) scene. It is not enough to meet this requirement only by defining the general model transformation languages. One of the reasons is that the general model transformation languages work at the level of metamodels of specific modeling languages, but not at the level of general design intentions. In this paper, a PSL (Pattern Semantic Link) metamodelling method is proposed. The heavyweight extension of the UML (Unified Mo. deling Language) metamodel is firstly carried out to formalize the patterns which can be used to express general design intentions. UML Action Semantics and the metamodel inheritance are then used to realize the automatic pattern generation and transformation. The proposed method can effectively support the coarse-grained model transformation at the level of general design intentions.
