This paper reports on experiences from establishing a reference architecture framework for the Norwegian Armed Forces. Like a number of other nations and NATO agencies, the armed forces chose TOGAF as their architecture development methodology (ADM), and the NATO Architecture Framework (NAF) for metamodel and content organization. In order to make TOGAF and NAF work together and address the par...

Metamodels are abstractions that are used to specify characteristics of models. Such metamodels are generally included in specifications or framework descriptions. A metamodel is for instance used to inform the generation of enterprise architecture content in the Open Group’s TOGAF 9 Content Metamodel description. However. the description of metamodels is usually done in an ad-hoc manner with c...
