I'd go with Stove providing the "Canon" - if not, it's certainly a safe default since it can translate between text and graphical representations to see what it means for a certain abbreviation.
If you are developing an app, ad say in the docs "this part uses pokerstove notation to describe a range" - I think everyone should be able to either understand immediately or if not learn easily.
We had a small thread on this a while ago:
