Querying along XLinks in XPath/XQuery: Situation, Applications, Perspectives

Erik Behrends, Oliver Fritzen, Wolfgang May


This paper summarizes the situation about using XLink for connecting XML instances. We discuss applications where XLink functionality can be useful, and derive requirements how the basic XLink technology should be supported in these scenarios. We compare several proposals dealing with interlinked XML data with our dbxlink approach which is a minimal extension to XLink and XPath, and we show how its semantics can be added to arbitrary XPath-based query engines.
