From the document: "a. IT that MILDEPs, CCMDs, and DAFAs develop, manage, and operate must be interoperable, to the maximum extent practical, with existing and planned systems (including applications) and equipment of joint, combined, and coalition forces, other U.S. Government departments and agencies, and non-governmental organizations, as required based on operational context. b. To maximize interoperability, IT will, to the maximum extent practical, support, provide, and use open-source, non-proprietary, and industry standard interfaces, data, and services."
