The NATO Architecture Framework is an Enterprise Architecture framework by the NATO derived from the DoDAF Enterprise architecture.
The current NATO C3 System Architecture Framework v2 (NAF v2), issued by NATO in September 2004 provides guidance on describing communication and information systems. Revision 3 of the NATO Architecture Framework (NAF), promulgated in November 2007, is identical to MODAF at its core, but extends the framework by adding views for Bandwidth Analysis, SOA and standard configurations.

NAF Meta-Model (NMM)

NAF uses the same meta-model as MODAF. The meta-model is documented in chapter 5 of the NATO Architecture Framework. Version 3.1 of the NMM is identical to v1.2.003 of the MODAF Meta-Model.
