By no means am I saying that the Zachman Framework (which he now labels an ontology) is the bees knees.  There are plenty of such frameworks—DoDAF, ToGAF, MoDAF—to choose from.

What I like about Zachman is its simplicity.

In the context of vocabularies... please to recognize you're going to need 36 vocabularies, one for each cell.  For certain there will be overlaps & commonality, but the basic issue is that the folks in mahogany row (Row 1) do not use the same language the stokers do (Row 6).

A lot of this language will not be found in formal dictionaries.

Remember the situation from my 1980 example... 70 different names for the core business concept "policy number."  I'd be willing to guess that with the tos & fros of business over the past 30 years, that number has NOT gone down.

Obviously most of the time a worker primarily deals with the language in their little box.  But there's plenty of activity at the edges of the cells too where language discrepancies need to be resolved... often by trial & error.
