Information model mapping is a necessary step in task solving over heterogeneous information resources in distributed information systems, digital libraries, subject mediators. For model mapping, close constructions of models are found and express one through another. Variety of constructions used in information models, may be reduced to a set of simple constituents. Upper level ontologies describe such constituents for wide classes of models (structural, object, behavioral, and others). Description of particular model constructions performed by combining concepts of upper level ontology and concretizing values of their properties. So in information modelís reference schema, which describes a set of its constructions and their relationships may be annotated by descriptions in terms of upper level ontology. The paper represents an approach to semantic integration of information models, based on discovering commonalities between descriptions of their constructions in terms of upper level ontology. Such integration is an essential step for model mapping.
