We present the whole querying process of our ontology based data integration proposal, that we call Semantic Mediator. The global schema (a TBox) is composed of the source schemas (also Tboxes) and a taxonomy, which links the sources to each other. The querying process is based on the global-schema's structure and consists of three steps: global query rewriting, source querying and global answer building. We describe the overall distributed system and the query-rewriting algorithm. Then we present an application of such a semantic mediation, the Personae project, which is for enabling historians to share their prosopographic data from the Middle Ages and the Renaissance.
