I think perhaps you do not understand what I am saying. Yes, there are quite a few such tools which allow laypeople and coders to come to an agreement. My point was about coming to and maintaining that agreement. Not how exactly you would go about doing that. I could think of about half-a-dozen good ways to formalize a domain. But even if your process is nothing more than "come to this room and let's talk"? It's difficult to get many people with many other duties in such a situation as much as it would be required. Don't forget -- and I'm sure you haven't -- that it's not just formalizing a language and grammar. It's the fact that these change over time as participants become more absorbed in the domain and see the same concepts from various viewpoints.
