Re: Name for a concept?

It seems to me that I called it an Ore condition, as suggested by Peter Johnstone, in my Acyclic Models book and I almost surely got that name from Gabriel-Zisman. Since it has been used that way in at least two books and generalizes a well-known condition from rings (also monoids) I see no good reason not to go with that.
