This paper presents a methodology based on data model translation for the management of interoperable information systems. The key features of this solution are 1) a set of abstract metatypes that capture the characteristics of various modeling concepts and 2) the organization of the metatypes in a generalization hierarchy to allow unification and correlation of data models. Description logic formalism is used to provide formal specification of the metatypes and a tool called "Strategic Hierarchy Builder" is defined to build the metatype hierarchy semi-automatically. The Strategic Hierarchy Builder organizes the hierarchy and implements an extensible metamodel in which new metatypes are created by specialization of existing metatypes.
