| 摘 要： | 元数据的存储是实现元数据管理的前提。介绍了一个基于XML的本体描述语言CRLE，以该语言作为元数据的基准，分析了CRLE语言与DTD文法的对应关系，并构造了把CRLE语言定义下的本体概念转换为DTD文档的算法，通过元数据和DTD的结合，实现了元数据的XML文档存储。实验表明，该算法可以有效地解决元数据的DTD文档存储。

| Abstract: | Metadata storage is the prior issue of metadata management. An ontology makeup language CRLE(concept representationlanguage for exchange) is introduced, which is based on XML and is used as basis of metadata, and the relationship between the CRLEand DTD is analyzed, then an algorithm to translate concepts defined by CRLE into DTD is illustrated. By the combination of metadataand DTD, metadata is stored into XML document. The experimental result shows that this method can efficiently store metadata usingDTD. |
