Abstract

XML is expected to become the next generation standard language for exchanging data over the Internet. In general, the contents of XML documents may change as time goes by, and then, it is important to capture entire histories of those documents. In this paper, we propose a logical data model for representing histories of XML documents. The proposed model extends the XPath data model, and is capable of representing change histories of XML documents. Various alternative approaches to the physical implementation of the model are also presented.
