Issue 462: Is P181 has amount different from P90 has value?
Posted by Robert on 6/12/2019
Is P181_has_amount really a useful property, compared to its super-property of P90_has_value?
They both take numbers, 181 is a subproperty of 90 just as 97 is a subclass of 54. Their scope notes do not describe any semantic difference between them, as far as I can tell:
P90: This property allows an instance of E54 Dimension to be approximated by an instance of E60 Number primitive.
P181: This property establishes the relationship between an instance of E97 Monetary Amount and the amount of currency, an instance of E60 Number, that it consists of.
As there is no specialization occurring, I do not believe that P181 is in any way different from P90 and thus we should just use P90 with Monetary Amounts and remove P181.

Indeed! P180 already specializes what kind of unit a monetary amount can have.
