面向对象方法在元数据研究中的应用

Applications of ObjectOriented for Metadata Research

摘要:

面向对象设计技术,将元数据标准中的元数据子集、元数据实体和元数据元素抽象为面向对象中的对象类和属性,将元数据管理中涉及的对象抽象为对象类,提出了元数据标准和元数据管理的对象模型.这种设计理念增强了元数据标准之间的兼容性、元数据管理的可扩展性及代码重用.

Abstract:

Multistandard coexistence and metadata management system reconstruction are presented in metadata research.The paper presents object models of metadata standard and metadata management system based on objectoriented design.Metadata section,metadata entity and metadata element are abstracted to be classes and properties,and the objects involved in management system are abstracted to be classes.In this way,compatibility between standards is strengthened.Management system extensibility and code reuse is improved.
