5.1 Introduction Ontology mediation is a process for establishing schema or data interoperability between two or more domain ontologies, whereas ontology mapping is the process of identifying concept and attribute correspondences between domain ontologies, usually via a matching process. Both ontology mediation and mapping enable ontologists to borrow and reuse rich schema dežnitions from existing domain ontologies already developed by other experts in their respective domains.
