A Comparison of XML-Based Temporal Models

摘要

Much research work has recently focused on the problem of representing historical information in XML. This paper describes a number of temporal XML data models and provides their comparison according to the following properties: time dimension (valid time, transaction time), support of temporal elements and attributes, querying possibilities, association to XML Schema/DTD, and influence on XML syntax. We conclude that the approaches of managing time information using XML mostly do not require changes of current standards.
