XML is the W3C standard document format for writing and ex- changing information on theWeb. RDF is theW3Cstandard model for describing the semantics and reasoning about information on the Web. Unfortunately, RDF and XMLalthough very close to each otherare based on two different paradigms. We argue that in order to lead the Semantic Web to its full potential, the syntax and the semantics of information needs to work together. To this end, we develop a model-theoretic semantics for the XML XQuery 1.0 and XPath 2.0 Data Model, which provides a unified model for both XML and RDF. This unified model can serve as the basis for Web applications that deal with both data and semantics. We il- lustrate the use of this model on a concrete information integration scenario. Our approach enables each side of the fence to benefit from the other, notably, we show how the RDF world can take ad- vantage of XML query languages, and how the XML world can take advantage of the reasoning capabilities available for RDF
