Datatype Mappings

This page provides mappings for the datatypes. There are mappings to HL7 V2, HL7 v3, and (where appropriate) vCard (see Mappings to Other Standards for further information & status).

V3 Mapping Issues for Identifier

When mapping an HL7 v3 II datatype to a FHIR Identifier, there are two possibilities:

• If the II has only a root and no extension, the FHIR Identifier will have a system of 'urn:ietf:rfc:3986' and the II.root will appear in Identifier.value
• If the II has both a root and an extension, the II.root will be mapped to a URI - either a human-friendly URL or URN or (less preferred) an OID expressed as a urn, and the II.extension will be sent in Identifier.value

To search on a CDA II.root - which may appear in either Identifier.system or Identifier.value, use the syntax identifier=|[root],[root].

vCard Mappings

• HumanName.text = vCard "FN" field
• HumanName.use = use of the vCard "TYPE" parameter
• HumanName.family, .given, .prefix, .suffix = parts of vCard "N" field. Note that there is no FHIR equivalent for the poorly defined "additional" name field. In FHIR, given names go in "middle" names
• The vCard nickname corresponds to a name with the use "nickname"
