Specification is not a gimmick; it is a real discipline that offers many advantages to software developers. It is helpful for building, managing and describing applications. Specification standards are now available, such as the OMG (Object Management Group) adoption of the UML (Unified Modelling Language) notation and the RM-ODP (Reference Model for Open Distributed Processing) standards developed by ISO (International Standardisation Organisation) and ITU-T (International Telecommunication Union-Telecommunication Sector). However, these standards are totally independent, even though they deal with the same topic. In order to conciliate these two approaches, we propose a way to use the UML notation to express RM-ODP enterprise concepts.
