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.

The MilOps domain in action

In 2016, DoD created the Warfighter Mission Area Architecture Federation and Integration Portal (WMAAFIP), an open source, centralized hub for architecture information on all of DoD’s capabilities. NIEM enabled DoD to share its architecture data dictionaries in a single, simplified, integrated view. Now, with information in a standardized structure and format, DoD can analyze and share information more effectively—even as DoD’s capabilities evolve and grow.

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