In Prospective Issues in Simulation Model Composability: Basic Concepts to Advance Theory, Methodology and Technology, a three-tier strategy is suggested to advance the composability infrastructure. Advances in the infrastructure are predicated on the developments in theory, methodology, and technology. Better understanding of the conceptual models of composable simulations is argued to be critical in improving the technology for composition. In particular, making context a significant component of such a conceptual model, and capturing, packaging, and distribution of the context is suggested to improve qualification of simulation models for composition. The notion of an agent-mediated model base technology that uses intelligent matchmaking and brokering mechanisms to operate on such context specification objects is suggested. The article 'Terrain Surface Codes for an All-Season, Off-Ride Motion Simulator describes the approach taken to relate terrain mechanics properties with the terrain database, in sufficient detail to support the TARDEC Ride Motion Simulator and additionally, allow consistency when interacting with Semi-Automated Force (SAF) vehicles within the OneSAF Test Bed (OTB), OneSAF Objective System (OOS) and potentially other simulators or simulations.
