Reusability of DDS Information-Model for Distributed VRE

Virtual Reality Environments (VRE) which simulate reality and thus present a safer learning environment, are increasingly being adopted to simulate complex systems. Such systems make the process of engineering virtual environments a complex task, especially due to the abundance of dynamic data types like behaviors. In parallel, distribution services have become essential following advances in telecommunications and the subsequent demand on mobile technologies. Hence, middleware enables technologies to provide such services to existing and newly-developed applications. Data Distribution Service (DDS) is a middleware standard for real-time applications based on a peer-to-peer architecture. DDS requires awareness about the type of distributed data which is achieved by defining an information-model. Consequently, distributing VRE using DDS complicates the development process of its information-model in order to meet the requirements of complex data types. In this paper, we propose a generic informationmodel in order to facilitate the structuring of domain models and ensure their reusability.
