The "Babel tower effect", induced by the heterogeneity of applications available in the operation of enterprises brings to a consistent lack of "exchangeability" and risk of semantic loss whenever cooperation has to take place within the same enterprise. Generally speaking, this kind of problem falls within the umbrella of interoperability between local reference information models .This position paper discuss some idea on this field and traces a research roadmap to make enterprise interoperable on the basis of this statement to face interoperability of RIMs by focusing the attention on the product. By applying a transformation between local information models into an "ontological reference model" centred on the product it is possible to insure applications interoperability.
