The convergence of open systems and interoperable systems

This paper sets out the case that technical ISR (Intelligence, Surveillance and Reconnaissance) System Interoperability is a sub-set of more general Open and Modular Information System design; both address the same architectural issues associated with layers, templates, interface specification, profiles, data models, process control and assurance. The paper develops a set of frameworks and models to enable those ISR specialists concerned with interoperability to engage with those concerned with open and modular information system infrastructures.
