摘要: 图形语言形式化描述体系由于需要一定的理论背景而不适于最终用户,为了满足最终用户对领域建模语言进行规范描述的需求,提出了一种可以描述图形语言二维语法结构的语言(EUVDL,End-User Visual Definition Language),分别从设计范型、抽象语法和具体语法3个方面考虑了最终用户的支持,并且给出支持最终用户使用的具体设计策略、设计了基于EUVDL的图形建模语言环境开发平台.通过和其他图形语言描述方法的比较以及实例演示,可以看出利用EUVDL描述图形建模语言具有语法结构简单、描述能力较强、支持描述重用的特点,适于最终用户使用.

Abstract: Formal specification of diagrammatic languages is not applicable to end users because of the requisition of computer theory. In order to satisfy the requirement of end users to define their own domain-specific modeling language, a language named EUVDL(end-user visual definition language),was proposed, which could be used to specify the 2-dimensional syntactic structure of diagrammatic model in software engineering. The specification technique of EUVDL combined the object-oriented methods and the rule-based approaches rather than formal specification. The support to end users was provided from following aspects: paradigm, abstract syntax, and concrete syntax. In order to make EUVDL available, the practical strategies for end users were presented and a framework for diagrammatic modeling environment generator was designed. Through comparison to other specification methods and demonstration of an example of visual process model, the conclusion can be drawn out that the specification method has the feature of simple structure, expressive power and reusable ability, and is adapted to end-users.
