摘要： 针对元数据管理和使用过程中存在的问题，提出一种新的元数据管理应用系统，介绍系统架构和层次划分机制，通过JAXB技术和O/R映射框架实现基于XML文档元数据的存储管理，利用HQL查询语言访问和检索元数据记录，并利用MVC模式实现基于Web的元数据检索。实验结果表明，该设计方案有效可行。

Abstract: Aiming at the problems existed in process of metadata management and application, a novel metadata management and application system is proposed. The system architecture and mechanism of level division are introduced. The storage and management of metadata are implemented by using JAXB technology and O/R mapping framework. The record of metadata is visited and retrieved by using HQL query language. MVC mode is used for the implementation of a prototype metadata search application. Experimental results show this design scheme is effective and feasible.

Key words: metadata, XML file, JAXB technology, O/R mapping framework, HQL query language, MVC mode
