元数据标准化在教育资源库共享中的应用

摘要

The construction of our educational resource database is short of unifed planning,which results in some problems such as repeat construction and inconsistent formal. Resource in the distance education system cannot propagate efficiently. To improve utilizing rate of network educational resource and share the data of different database with different structure,the paper designed a model of educational resource metadata management platform and put forward a scheme about metadata standardization technology of educational resource database based on XML and study a method of date exchange based on formwork. This scheme can change other structure data to XML by complying with metadata of educational resource and implementing directives and,which can achieve the sharing and exchange of data in different educational resource database.%目前我国各院校的教育资源库的建设缺乏统一规划,存在重复建设、数量庞杂、形式不规范等问题,使得网络远程教育系统中资源信息不能有效共享传播.为提高网络教育资源的利用率,共享不同结构的资源库的数据,设计一个教育资源元数据管理平台模型,并提出了基于XML的教育资源库元数据标准化的方案,研究了基于模板的XML数据转换方法,通过指令的执行,并应用教育资源元数据标准,将其他格式的数据通过模板转化成XML文档,从而实现不同教育资源库之间数据的互换和共享.
