In the last decade, the ontologies are used in order make understandable the data, and to be a support (or system's interoperability problems. As shared common vocabulary. the ontologies play a key role in resolving partially the semantic conflicts among systems. Since, ditTerent applications of the same domain have several representations oethe same real world entities, our aim is to propose MurO: a Multi-representation ontology. The latter is an ontology characterizing the concepts by a variable set o( properties (static and dynamic) or attributes in several contexts and in several scales of granularity. We introduce first the MurO formalism. Then, we show its use with the ongoing EISMO (Enterprise Information System Multi-representation ontology) project and its relevance for answering the motivating requirements.
