摘要: 内容管理系统(CMS)的元数据管理是其核心模块,负责记录内容的描述信息和帮助其他模块快速定位相关内容,元数据索引是为检索提速的关键技术。根据XML语言的特点,可采用它作为元数据的描述语言,因此元数据索引问题转变为XML文档的索引问题。该文在对XML数据进行形式化描述的基础上,分析了XML索引算法的特点,针对CMS元数据的特点,提出了一种支持动态更新的XML索引算法。

Abstract: Metadata management is a core module in content management system(CMS), which is responsible for noting description information of content and assisting to find out interrelated content quickly for other module. Metadata index is a kind of key technology to increase search speed. According to the character of XML, it is adopted to become description language of metadata. So the question of metadata index is converted into XML document index. This article describes XML data formally, and analyzes the character of algorithm of XML index and puts forward a kind of algorithm of XML index that supports dynamic update.
