Model issue: currency unit vs currency resource type

[bhaugen]

We got currency Units and currency Resource Types whose unit is the currency unit.

For example, in Sensorica, we got Canadian Dollars whose unit is the currency Canadian Dollars.

Something is probably wrong with this picture, but I don't know exactly what it is or how to fix it.

We also have Virtual Account Resources, Economic Events, prices, and other things measured in CAD, so the CAD currency Unit seems to be necessary, and is not always a duplication.

And then we got Payments and other Economic Events whose Resource Type is CAD the Resource Type and whose unit is CAD the currency Unit. So in that case, it is a duplication.

We may need to consult a philosopher...

I asked Lynn, why didn't we just have Money as the Resource Type and then the currency CAD or USD or Euro or Yen or whatever would not be duplicate information.

She reminds me that a Resource Type must have a unit. That's why we have all of those currency-specific Resource Types.
