The Framework is the Ontology
I have no idea where people get the idea that the Zachman Framework requires any documentation at all. The Zachman Framework is an ontology – the theory of the existence of essential components of an enterprise (actually, of anything) that warrant description in order to successfully create it, operate it or change it. Whether any or all of those components are described (documented, made explicit) is a function of a methodology and the choice of the Enterprise… not a requirement of the Framework.
