Class Description
Commodities in the context of IEC 62325 are MarketProducts (energy, regulation, reserve, etc) traded at a specific location, which in this case is a Pnode (either a specific pricing node or a pricing area or zone defined as a collection of pricing nodes). The CommodityDefinition is a container for these two parameters, plus the unit of measure and the currency in which the Commodity is traded. Each CommodityDefinition should be relatively static; defined once and rarely changed.
