<p>A major challenge in building the Semantic Web is resolving the differences among heterogeneous databases. After the rise of XML as the global standard for data interchange, researchers are developing techniques to handle data integration. So far, most approaches have focused on syntactic and schematic heterogeneities. This article illustrates an approach that leverages current XML technologies and the hierarchical organization of the data to resolve semantic heterogeneities. Two real-world cases from the field of geographic information systems illustrate the approach.</p>
