Introduction
Monetary Amounts are similar to Dimensions in that they are primarily a value
with a unit to clarify what the number refers to, but in this case the unit is a currency
. The amount is a particular instance of a value/currency combination, so there can be multiple amounts each of which have the same value and currency, but are used in different models. This is the same as the way there can be multiple dimensions with the same classification, value and unit used in different models.
In the Linked Art API and model, amounts are only used in the Provenance Activity structure, as described in the Provenance model documentation.
Property Definitions
The monetary amount data structure has the following properties.
