392. Applying existing NATO standards or - in those areas where NATO STANAGS do not yet exist - International Standards are key for achieving interoperability in a federated environment. The dynamic nature of future operations results in unforeseen information exchange requirements within and across the supporting force. This might require the development and design of new Joining, Membership and Exiting Instructions (JMEI) for systems/capabilities within Combined Endeavor which do not exist. Since CE will not have a ‘formal’ body for Change management like the Coalition Interoperability Assurance and Validation (CIAV) Working Group, changes will most likely be part of CE Planning Conferences and/or execution schedule. CE will not develop new data exchange formats and leave that to other venues such as ACT led CWIX. JMEI shall be evaluated and developed in-line with existing NATO policies and guidelines so that they can be quickly transformed into standards (e.g. STANAGS) by the appropriate NATO Bodies based on the NATO Bi-SC Data Strategy, the NATO NNEC Data Strategy, and when appropriate, based on the APP-15 process. The CEMN Profile is maintained by the CEMN CJ6 Working Group and is expected to be upgraded every 12 months.

393. ADatP-34 defines four stages within the life-cycle of a standard: emerging, mandatory, fading and retired; in those situations where multiple stages are mentioned, the CEMN Profile recommends dates by which the transition to the next stage is to be completed by all CEMN members. If a nation decides to implement emerging standards it is her responsibility to maintain backwards compatibility to the mandatory standard.

394. Any discrepancies discovered between different elements of this Profile, shall be resolved through a change proposal prepared by the responsible NATO body or a CEMN member nation.

395. CEMN Profile change requests can only be submitted by NATO civil or military bodies or CEMN member nations.

396. The CEMN CJ6 Working Group will review updates to ADatP-34 and CEMN Profile change proposals and if required will produce a new version of the CEMN Profile. The CEMN profile of the NISP is reviewed by the CEMN CJ6 Working Group on a annual basis and requests for formal adoption by the Interoperability Profile Capability Team (IP CaT) are made by the WG on an annual basis.
