JC3IEDM is an evolution of the C2IEDM standard that includes joint operational concepts, just as the Land Command and Control Information Exchange Data Model (LC2IEDM) was extended to become C2IEDM.
"[2] According to JC3IEDM's documentation,[3] this aim is attempted to be achieved by "specifying the minimum set of data that needs to be exchanged in coalition or multinational operations.
Any addition that is deemed to be of general interest may be submitted as a change proposal within the configuration control process to be considered for inclusion in the next version of the specification."
Toward that end, it lays down a common approach to describing the information to be exchanged in a command and control (C2) environment.
Subsequent releases have seen areas of the model developed in greater depth than others and there is variation in the number of sub-types and attributes for each type in the current version.
