We develop a framework of characteristics, essential and recommended, that a data model should have to be suitable as canonical model for federated databases. This framework is based on the two factors of the representation ability of a model: expressiveness and semantic relativism . Several data models are analyzed with repect to the characteristics of the framework, to evaluate their adequacy as canonical models.
