基于元模型的企业模型表达

Meta-model-based enterprise model expression

为了促进不同建模方法所建模型之间的信息集成和共享,并解决目前各种建模技术和建模语言之间的差异所造成的多模型驱动系统集成的障碍,该文以模型驱动体系结构(MDA)思想为基础,从元模型层面提出图形层和概念层分离的建模软件开发思路,构建了以可扩展标记语言(XML)作为数据交换格式的通用企业建模工具系统框架,利用元模型描述相关建模方法的语法和语义。以IDEF3建模方法为例,验证了系统框架中元模型XML模式(Schema)的构建方法,通过元模型实现了模型之间的信息交互和共享。

Complex enterprise systems can not easily realize information integration and sharing. However, the model driven architecture （MDA） is emerging as a technique to implement integration and interoperability between information systems. This paper presents a meta-modeling framework for enterprise modeling methods using conceptual and graphical layers in the modeling methods. The general enterprise modeling framework based on the XML （extensible markup language） format provides the user with a method to define a modeling method. This modeling framework enables information exchange and sharing between models. An IDEF3 meta-model implemented to validate the framework shows how information communication can occur between different models.
