Abstract
Open distributed systems are complex systems, which contain a lot of components provided by different vendors and built with different technologies. The use of well-established and standardized modeling techniques is one way to deal with the problems that occur in the specification and development process of these systems. Enterprise Architecture Frameworks provide a good foundation to structure the various required modeling techniques. Existing modeling solutions in the context of Enterprise Architecture Frameworks do not provide optimal support for the specification of open distributed systems. In this paper a coherent MODeling approach for open distributed systems using an Enterprise Architecture framework (MODEA) is developed. The approach uses the latest OMG modeling standards. As an enterprise architecture framework the Reference Model for Open Distributed Systems (RM-ODP) has been chosen. Finally MODEA is illustrated through the specification of two case studies.
