The MilOps Domain provides a catalogue of data components necessary to support improved data interoperability between DOD and mission partners for operations.


The MilOps Domain is stewarded by the Joint Staff, as requested by the DOD Chief Information Officer (CIO). A MilOps Domain Configuration and Control Board (MilOps CCB) was formally stood up in March 2014. The MilOps CCB manages domain content and addresses technical issues arising from the development of Information Exchange Package Documentations (IEPDs) using MilOps Domain Content. NIEM is the identified and preferred semantic solution for interoperability by the DoD Chief Data Officer (CDO), Chief Information Officer (CIO) and the Secretary of Defense as defined in the DoD Instruction (DoDI) 8320.07; Implementing the Sharing of Data, Information, and Information Technology (IT).

The MilOps domain in action

In 2014 the U.S. Army won a Best of NIEM award for their Tactical Infrastructure Enterprise Services Coalition Warfare Program (TIES CWP). TIES CWP used NIEM to improve interoperability and information sharing between the U.S. and coalition partners.
