The Real-time Platform Reference Federation Object Model (RPR FOM) enables linking computer simulations of discrete physical entities into complex virtual worlds.
It is a High Level Architecture (HLA) federation object model developed for distributed simulation applications of defense and security.
[3] The standard consists of two parts: When the High Level Architecture was introduced by the US Department of Defense in 1996 the RPR FOM effort was initiated to facilitate the migration from DIS to HLA.
The development of RPR FOM 2.0 started in 2000, but came to a halt in 2007, resulting in a widely used draft version 17.
Development of this upcoming version was started in 2016 by the SISO DIS and RPR FOM Product Support Group.
