Interconnectivity via a consolidated type hierarchy and XML

Abstract

We propose building a software system that passes any message type between legacy Command, Control, Communications, Computer, Intelligence, Surveillance and Reconnaissance (C4ISR) systems. The software system presents significant cost savings to the Department of Defense (DoD) because it allows us continued use of already purchased systems without changing the system itself. In the midst of the information age, the DoD cannot get information to the warfighter. We still maintain and use heterogeneous legacy systems, which send limited information via a set of common messages developed for a specific domain or branch of DoD. Our ability to communicate with one message format does not meet our needs today, though these stovepipe C4ISR systems still provide vital information. By combining these systems, we will have a synergistic effect on our information operations because of the shared information. Our translator will resolve data representational differences between the legacy systems using a model entitled the Common Type Hierarchy (CTH) . The CTH stores the relationships between different data representations and captures what is needed to perform translations between the different representations. We will use the platform neutral extensible Mark-up Language (XML) as an enabling technology for the CTH model
