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.
