【摘要】 分析了目前元数据管理的研究现状和存在的问题;按照OMG的MOF规范,建立了统一的MOF元元模型,对不同领域的元模型进行统一描述;提出了一个高度可集成可扩展的元数据管理框架和元模型建模规范;介绍了主题与元模型的相容约束规则以及主题与元数据的访问约束规则;通过采用对元数据按主题进行动态分类的方式,实现了对元数据的多维管理。更多还原

【Abstract】 Current situation and problems in the research of meta-data management are analyzed.According to the criterion of MDA MOF,a uniform meta-meta-model of MOF is build.In the model,meta-models in various domains is described uniformly.A highly-integration and extensible framework of meta-data management and the criterion of modeling meta-model are presented.The consistent regulation between subject and meta-model is introduced as well as the accessible rule between subject and meta-data.By means of clas-sifying meta-data in the light of subject dynamically,the multi-dimension management of meta-data is implemented.更多还原
