基于XML的教育资源库元数据标准化研究

Metadata Standardization of Educational Resource Database Based on XML

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,针对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,使网络远程教育系统中资源信息不能有效共享传播的问题,提出了基于XML(eXtensible Markup Language)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。

To improve the utilizing rate of network educational resource and share the data of different database with different structure,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 can not propagate efficiently.Put forward a scheme about metadata standardization technology of educational resource database based on XML（eXtensible Markup Language） 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 which can achieve the sharing and exchange of data in different educational resource database.
