I'll note that keeping all of this in sync is going to be challenging. I don't think we have any other renames coming up. During the last call, we had noted that we wanted to automate the generation of the human-readable vocabulary file, JSON Schema, and a variety of other things. Multiple tools were suggested -- that issue is being tracked here: #998
