JC3IEDM
The Joint Command, Control and Consultation Information Exchange Data Model is first and foremost an information exchange data model. The model can also serve as a coherent basis for other information exchange mechanisms, such as message formats, currently lacking a unified information structure. It is the most current evolution in a long line of data model as far back as the Generic Hub GH. JC3IEDM is intended to represent the core of the data identified for exchange across multiple functional areas and multiple views of the requirements. Toward that end, it lays down a common approach to describing the information to be exchanged in a command and control (C2) environment. The JC3IEDM has recently been updated to include Improvised Explosive Devices (IED) and Irregular Actors (IA).
