==Realtime Platform Reference FOM (RPR FOM)==
The [[RPR FOM]] is a Federation Object Model (FOM) for the High-Level Architecture designed to organize the PDUs of DIS into an HLA object class and interaction class hierarchy. It has been developed as the SISO standard SISO-STD-001.<ref>{{cite web |title=Guidance and Rationale and Interoperability Modalities for the Real-time Platform Reference FOM |url=https://www.sisostds.org/DesktopModules/Bring2mind/DMX/Download.aspx?Command=Core_Download&EntryId=30822&PortalId=0&TabId=105 |website=SISO |access-date=5 September 2018}}</ref> The purpose is to support transition of legacy DIS systems to the HLA, to enhance a priori interoperability among RPR FOM users and to support newly developed federates with similar requirements. The most recent version is RPR FOM version 2.0<ref>{{cite journal |title=RPR FOM 2.0: A Federation Object Model for Defense Simulations |url=https://www.sisostds.org/DigitalLibrary.aspx?Command=Core_Download&EntryId=42390 |journal=Proceedings of 2014 Fall Simulation Interoperability Workshop |date=Sep 2015}}</ref> that corresponds to DIS version 6.
