Add Money data type

Description

Currently there is no Money data type in openEHR. An equivalent of the HL7 type for money (value, currency, ordered quantity of some kind) is expected to be satisfactory. Requirements:

  • uses ISO currency codes

  • allows representation of exchange rate multipliers & date provided & who by

  • indicator of whether originally stated in that currency or another

  • should be able to act as a front end of a currency / exchange rate service

Normally money has a specific precision that is not properly supported by a traditional double type.

Might be worth supporting this separate from DV_QUANTITY for this reason more than the units reason.

I know this is important in health administration information, but I wonder how much it would be used in the EHR, which reduces the priority from my perspective..

I'd have to disagree with you Heath re priority - I'd say my experience is this is a foundational type of data captured in healthcare delivery. Perhaps not so important in research type but again in health policy, management etc. this would be a centrepiece.
Besides it'd be good for alignment with FHIR.

I'll stand corrected Koray, but I haven't seen an archetype with a currency concept in it yet.

You're absolutely right that we don't have any Archetypes but perhaps it's because we don't have the means to represent it
I think having the ability will cause otherwise non-Archetyped information be modelled using Archetypes. I'd go on to say we don't have much ADMIN_ENTRY type archetypes in first place.

Do we need a just datatype or a "financial model" like v3 has?
Maybe with just ADMIN_ENTRY and the money DT we can have enough expresiveness to mimic v3 and other financial models (like representing an invoice, an account a claim, etc). But I'm not sure since I never used the IM to express such info. Does anyone has some experience modeling these things with the IM?
