In today's distributed simulation world, there are several standards available for conducting real-time, platform-level wargaming across multiple, geographically dispersed locations. The most common standards used in military simulations are Distributed Interactive Simulation (DIS), High level Architecture (HLA) and Test and Training Enabling Architecture (TENA). The biggest challenge using different standards in the same wargame is to provide interoperability between the simulations to exchange data via a common set of exchange formats, called enumerations. However, each interoperability standard defines enumerations in its own way, according to its unique data structure. TRADOC's Battle Lab Collaborative Simulation Environment (BLCSE) federation simulation architecture consists of DIS and HLA based federates and utilizes OneSAF as a main entity driver in the federation. It has become apparent that the BLCSE federation needed a methodology to translate objects' definitions between the different standards used in the federation. Our engineering team has developed a methodology to utilize translation tables to provide interoperability between the various federates. Although our methodology successfully served the BLCSE federation for several years, it was labor-intensive and error-prone. Additionally, each new entity introduced into the federation required a FOM update to include related new enumeration. This year, our engineering team introduced a better methodology to reduce the time and man-power to obtain the target results and eliminate periodic FOM updates. They developed a method to utilize existing DIS enumeration tables to provide interoperability between the various HLA federates and OneSAF. It was proved that using only DIS enumerations throughout the federation would save time and effort. However this required some changes in the OneSAF and other federates' software. This paper will detail the procedural and technical implementation that combined legacy enumeration synchronization models and modern interoperability framework into one unified approach including sample OneSAF code.
