The MAIN function of the High LEVEL Architecture is to ESTABLISH a common infrastructure, or the foundation, for a building other components of a system. The infrastructure is then used and re-used by other components of a system that rely on COMMUNICATION and other resources through HLA. This non-software blueprint of a system has been used by the AMG to create an environment that supports interoperability and reusability. Interface specification is used to coordinate communication efforts of various components that are built on top of the HLA.
