Exploring agent-supported simulation brokering on the semantic Web: foundations for a dynamic composability approach

Federated simulations address the need for interoperability, as well as the improvement of reuse and composability. The focal goal in a federated simulation is to facilitate composable simulations by standardizing interfaces to assure technical interoperability among disparate simulations. Yet, existing federated simulation infrastructures neither facilitate substantive interoperability nor are dynamically extensible. Emergent Web services technologies hold out the potential to significantly improve the development of interoperable, extensible, and dynamically composable federations. As such, recent initiatives (i.e., XMSF) are urging the use of open standards that can be applied within an extensible framework for next generation modeling and simulation applications. We discuss how the realization of multimodel and multisimulation formalisms in terms of semantic Web and agent technologies may bring new vistas to demonstrate runtime model discovery, instantiation, composition, and interoperation.
