Extension: PQ-translation

FHIR Infrastructure Work Group

Maturity Level: 1

Informative

Use Context: Any

URL for this extension:

http://hl7.org/fhir/StructureDefinition/iso21090-PQ-translation

Status: draft. Extension maintained by: Health Level Seven International (Modeling and Methodology)

An alternative representation of the same physical quantity expressed in a different unit from a different unit code system and possibly with a different value.

Comment:

It is not necessary for information processing entities to check and enforce that the translations are valid translations of the base unit, but they are allowed to do so, and to reject instances where the translations are not valid. NOTE Translations are allowed to contain other representations in UCUM units, but there is generally no point to this as it is possible to convert from one UCUM form to another.

Context of Use: Use on Element ID Quantity
