The US Department of Defense DoD is currently launching itself into the Global Information Grid GIG environment. Although we may not know the full shape of the GIG or even its implication for Modeling and Simulation MS at this point, there are some significant aspects of the GIG upon which we can build to become capable participants in this new world. The Defense Information Systems Agency DISA, which is the organization responsible for building the GIG, and the Defense Modeling Simulation Office DMSO, which is the focal point for MS in DoD, teamed to provide critical technical and operational concepts that have the potential to change dramatically the way we look at distributed simulation. Regardless of how the GIG finally emerges, we know certainly that it will be based on a Service-Oriented Architecture SOA. The GIG comprises four domains that are used to group and categorize the services. DISA is actually working on standards, service stacks, and service definitions. These standards and definitions will provide the core upon which we build MS services in the future. We will describe how using these services will change the way we look at MS standards how existing and emerging data models provide a critical part of the solution and where we are going with the HLA. In particular we will exploit web services, as they are currently the choice for implementing SOA. Topics included are the web service stack standards being adopted by the GIG and their implication for service providers how ontologies, taxonomies and data models play in web services what standard data models are being used how MS needs to look at standards in the light of GIG services and how this affects the review of the IEEE1516 HLA standard.
