Unified Reversible Life Cycle for Future Interoperable Enterprise Distributed Information Systems

Abstract

This paper aims at improving the re-implementation of existing information systems when they are called to be involved in a system of systems, i.e. a federation of enterprise information systems that interoperate. The idea is reusing the local experiences coming from the development of the original information system with the process of Model Discovery and Ontological approach. We give first, a review of ongoing researches on Enterprise Interoperability. The MDA can help to transform concepts and models from the conceptual level to the implementation. The HLA standard, initially designed for military M&S purpose, can be transposed for enterprise interoperability at the implementation level, reusing the years of experiences in distributed systems. From these postulates, we propose a MDA/HLA lifecycle to implement distributed enterprise models from the conceptual level of federated enterprise interoperability approach. In addition to this classical development, we propose a model reversal methodology to help re-implement the legacy information system, in order to achieve the interoperability with other systems.
