Abstract: The paper proposes an approach to storing semi-structured data based on XML, and develops algorithms for storing and parsing. Because OEM is a data model with graph structure while common data model for XML is tree structured, the key problem is that how to map data with graph structure into data with tree structure. The problem can be solved by utilizing semantic information of element and attribute of XML data.

摘要： 提出了一种基于XML存储半结构化数据的方法，设计并实现了相应存储与解析算法。鉴于OEM模型是一种图状模型，而通常的XML数据模型是树状模型，为此需解决图状模型数据映射为树状模型数据这一关键问题，利用XML元素和属性的语义信息可从语义级别解决该问题。
