Architecture for a reuseable object-oriented polymorphic middleware

Using a middleware when designing a new distributed application allows portability across numerous software and hardware architectures, but introduces a new layer of potential incompatibilities due to the existence of various middleware standards. This paper presents the architecture of DROOPI (Distributed Reusable Object-Oriented Polymorphic Infrastructure). This project aims at defining and implementing a modular middleware emphasizing software reuse, customizability towards environment and application requirements, and transparent interoperability through the support of multiple middleware personalities. Some of these capabilities may be found in similar projects. Our objective is to bring all these properties in a single environment, enabling communication between various components using different middleware standards.
