实现科学数据共享的基石语言——XML的理论与应用

Basic Language for Implementing Scientific Data-sharing: XML'S Theory and Application

本文介绍了逐渐成为新世纪网络“国际语言”的XML;阐述了其在标记语言设计、数据交换与整合、内容管理、Web服务、语义网等应用领域中的核心地位;分析了其在学科标记语言设计、元数据技术系统、通用科学数据描述与发布、互操作能力、元数据目录服务、精确数据服务与个性化功能服务、数据网格等科学数据共享管理诸方面的基石作用,指出了XML对于科学数据共享技术平台构架建设的重要意义;最后展望了基于XML的科学数据共享实施策略。

The paper introduces XML, the international language for the network world during the new century. A discussion is given for XML's central role in such varied applications as markup language design, data interchange and integration, content management, Semantic Web, Web Services and value-proof, and an analysis is put into for its basic function in such scientific data-sharing areas as subject markup language design, metadata technology system, generalized scientific data description and distribution, interoperability, precise data services, personalized services and data grid, indicative of XML' s great implication for the construction of the technology architecture for the scientific data-sharing. The paper ends with prospecting for the XML-based scientific data-sharing implementation strategies.
