Yes yes, normalization would be nice to, though a little beyond what I 
am (or was) thinking of currently. Going back to how 
event_definitions.yaml is the best 'source' we have currently, is it 
possible to rip out (for now) event_definitions.yaml  and I assume the 
python code-gen part from ceilometer into a new library (and/or repo); 
at least this would be a small step forward (I think).

Perhaps this may have already been planned to?

Assuming that at some point nova has its notifications in object format 
(which allows for getting a json schema) then nova could make that 
schema set fetchable (and the other projects do the same thing) then we 
could see where that ship goes and adjust this new repo to accommodate that.
