1.18.3 Data Type Mappings

This page provides mappings for the data types. There are mappings to HL7 v2, v3, and (where appropriate) vCard.

Primitive Types

Complex Types

1.18.3.1 Primitive Types

See also Base Definition, Examples and Detailed Descriptions.

Data Type	V2	RIM
base64Binary	~ED	BIN
boolean	n/a	BL
date	DT	TS
dateTime	DTM	TS
decimal	~NM	REAL
instant	DTM	TS
integer	~NM/~SI	INT
string	ST	ST
time	TM	n/a
uri	n/a	URL

1.18.3.2 Attachment

1.18.3.3 Mappings for HL7 v2 (http://hl7.org/v2)

Attachment	ED/RP
contentType	ED.2+ED.3/RP.2+RP.3. Note conversion may be needed if old style values are being used
language
data	ED.5
url	RP.1+RP.2 - if they refer to a URL (see v2.6)
size
hash
title
creation

1.18.3.4 Mappings for RIM (http://hl7.org/v3)

Attachment	ED
contentType	./mediaType, ./charset
language	./language
data	./data
url	./reference/literal
size	N/A (needs data type R3 proposal)
hash	.integrityCheck[parent::ED/integrityCheckAlgorithm="SHA-1"]

1.18.3.5 Identifier

See also Base Definition, Examples and Detailed Descriptions.

1.18.3.6 Mappings for HL7 v2 (http://hl7.org/v2)

Identifier	CX / EI (occasionally, more often EI maps to a resource id or a URL)
use	N/A
type	CX.5
system	CX.4 / EI-2-4
value	CX.1 / EI.1
period	CX.7 + CX.8
assigner	CX.4 / (CX.4,CX.9,CX.10)

1.18.3.7 Mappings for RIM (http://hl7.org/v3)

Identifier	II - see see identifier pattern at http://wiki.hl7.org/index.php?title=Common_Design_Patterns#Identifier_Pattern for relevant discussion. The Identifier class is a little looser than the v3 type II because it allows URIs as well as registered OIDs or GUIDs. Also maps to Role[classCode=IDENT]
use	Role.code or implied by context
type	Role.code or implied by context
system	II.root or Role.id.root
value	II.extension or II.root if system indicates OID or GUID (Or Role.id.extension or root)
period	Role.effectiveTime or implied by context
assigner	II.assigningAuthorityName but note that this is an improper use by the definition of the field. Also Role.scoper
