This paper describes the techniques, which are being developed and used by Bevilacqua Research Corporation (BRC), to address the cooperative development and reuse of knowledge for intelligent simulations. The work is based on the use of the draft proposed American National Standards (dpANS) Conceptual Graph standard that defines a Conceptual Graph Interchange Format (CGIF). This standard, while originated for Conceptual Graphs, offers the flexibility and robustness to describe knowledge. The knowledge description can then be utilized in any application that can understand the dpANS standard. The paper summarizes the state of the current standardization efforts, then discusses parsing CGIF, and concludes by discussing knowledge applications and some implications of the standardization of knowledge representations.
