Extension: Translation

Official URL: http://hl7.org/fhir/StructureDefinition/translation Version: 5.3.0-ballot-tc1
Standards status: Trial-use Maturity Level: 3 Computable Name: Translation
Other Identifiers: OID:2.16.840.1.113883.4.642.5.1583

Language translation from base language of resource to another language, used to provide translations for strings, including markdown. Generally, the type of the translation extension SHOULD match that of the element being extended.

It is also allowed to provide translations of elements of type code, which may be appropriate to use for rendering when the code itself is a natural language word (usually in English). In such cases, the translation is not provided as an alternative code, and is not intended for machine interpretation. This extension should never appear on a code that is part of a Coding, as placing the translation on Coding.display is more appropriate.

Context of Use
