Interoperability in networked systems of systems: the issue here is how to achieve semantic consistency among systems that were not designed to interoperate and do so quickly and efficiently. The specific software systems I have been funded to study are military command and control and simulation systems. The Mason C4I Center team that I lead has developed middleware software that enables interoperation of systems developed by various nations participating in the NATO Modeling and Simulation Group. An instance of six command and control systems from different nations interoperating with five simulation systems from different nations has been demonstrated, and the work continues to move forward. This inherently involves international collaboration and also has been the basis of industry support from Saab, MAK, and ESRI Networked multimedia for distributed education and collaboration: the hard problem here is how to build systems that are most effective within the framework of group psychology for collaboration and learning and also work well over the evolving Internet.
