摘 要: XML作为一种数据交换的国际标准,已经贯穿于Internet应用的各个领域之中。而XQuery也能够有效地查询和处理XML文档。这些技术的日渐成熟推动了数字图书系统的发展,也使得图书信息的修订愈加容易,版本更新更加频繁。为合理有效的组织和管理这些多版本的图书信息,方便用户查询,设计完成一个有效支持版本管理和历史信息查询的新型数字图书系统。 XML has become widely accepted for both representation and exchange of data over the Internet. And XQuery as a standard query language is very helpful for searching and querying XML data. These entire make digital libraries possible also make it too easy to revise documents and publish new versions. Thus version management and historical queries have become a critical issue characterized by significant new challenges and opportunities. In this paper we propose a new XML-based digital library system that supports version management and historical queries.
