The United Kingdom Ministry of Defence (UK MOD) has a vision for utilisation of a range of common simulation services and components which aim to reduce Modelling and Simulation (M&S) acquisition and support costs and promote re-use across the UK defence enterprise. The Simulation Composition and Representation of Natural and Physical Environments (SCORE) is a joint industry and Defence Science and Technology Laboratory (Dstl) research project which is providing advice and recommendations to de-risk this vision. Under SCORE and the related Architecture Interoperability and Management of Simulation (AIMS) project, a range of studies into providing services and components as a service are being undertaken, with links into the NATO Modelling and Simulation Group (MSG)-136 Modelling and Simulation as a Service (MSaaS) activity. This paper provides an overview of work undertaken within the first 2 years of the SCORE project associated with de-risking the delivery of non-runtime simulation services. This includes research to understand how data, behaviours, scenarios and other simulation components can be most effectively stored, codified and accessed. Work to date has drawn upon approaches undertaken in adjacent areas of defence to modelling and simulation, such as geospatial data, to evaluate candidate registry and repository solutions. The study has also included the development of data models and frameworks which can most effectively reflect data storage and retrieval requirement. The paper will discuss development and experimentation of these capabilities as part of efforts to inform a potential UK MOD approach to delivering Modelling and Simulation as a Service.
