JC3IEDM, or Joint Consultation, Command and Control Information Exchange Data Model is a model that, when implemented, aims to enable the interoperability of systems and projects required to share Command and Control (C2) information. 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. The program is managed by the Multilateral Interoperability Programme (MIP). The Joint C3 Information Exchange Data Model JC3IEDM is produced by the MIP-NATO Management Board (MNMB) and ratified under NATO STANAG 5525. JC3IEDM a fully documented standard for an information exchange data model for the sharing of C2 information. The overall aim of JC3IEDM is to enable "international interoperability of C2 information systems at all levels from corps to battalion (or lowest appropriate level) in order to support multinational (including NATO), combined and joint operations and the advancement of digitisation in the international arena." According to JC3IEDM's documentation, this aim is attempted to be achieved by "specifying the minimum set of data that needs to be exchanged in coalition or multinational operations. Each nation, agency or community of interest is free to expand its own data dictionary to accommodate its additional information exchange requirements with the understanding that the added specifications will be valid only for the participating nation, agency or community of interest. 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." "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 structure should be sufficiently generic to accommodate joint, land, sea, and air environmental concerns. The data model describes all objects of interest in the sphere of operations, e.g., organizations, persons, equipment, facilities, geographic features, weather phenomena, and military control measures such as boundaries. Objects of interest may be generic in terms of a class or a type and specific in terms of an individually identified item. All object items must be classified as being of some type (e.g. a specific tank that is identified by serial number WS62105B is an item
