摘要

我们描述了DataFoX，它是XML文档的一种新的查询语言，它扩展了Datalog，支持树作为变量的域。我们还为DataFoX引入了一种层代数，它支持语言级别的数据异构性，以及几种基于代数的评估技术。

Querying spatiotemporal XML using DataFoX

We describe DataFoX, which is a new query language for XML documents and extends Datalog with support for trees as the domain of the variables. We also introduce for DataFoX a layer algebra, which supports data heterogeneity at the language level, and several algebra-based evaluation techniques.
