While current mediators for information integration address and solve the problems of syntactic and structural heterogeneities amongst sources using a semistructured data model like XML [GMPQ + 97, CDSS98, GMW99], the semantic integration problem remains and a mediation engineer has to come up with integrated view definitions on top of the different XML views and DTDs exported by sources. In contrast to this structure-centered approach, the model-centered me
