The combination of semistructured data from different sources on the Internet often fails because of syntactic and semantic differences. The resolution of these heterogeneities requires explicit context information in the form of metadata. We give a short overview of a representation model that is well suited for the explicit description of semistructured data, and show how it is used as the basis of a prototype for metadata-driven integration of heterogeneous data extracted from
