Large amounts of data are managed by organizations, available to be viewed and analysed from multiple perspectives, which becomes a fundamental resource to the effectiveness of the organizations. An organization can achieve full benefit from the available information by managing its data resource, through the planning of its exploitation and its maintenance. The concept of data repository fulfils these requirements, due to the fact that it contains the de-scription of all types of data produced, managed, maintained and exchanged in an organization. This paper describes an experience of the use of an existing repository of conceptual schema, representing a wide amount of entities of in-terest for Central Public administration, in order to produce the corresponding repository of the administrations located in a region. Several heuristics are de-scribed and experiments are reported.
