HL7 Terminology (THO)

This page is part of the HL7 Terminology (v3.1.0: Release) based on FHIR R4. This is the current published version. For a full list of available versions, see the Directory of published versions

NamingSystem: Uniform Resource Identifier (URI)

Official URL: http://terminology.hl7.org/NamingSystem/uri Version:
Active as of 2022-02-07 Computable Name: URI

As defined by RFC 3986 (http://www.ietf.org/rfc/rfc3986.txt)(with many schemes defined in many RFCs). For OIDs and UUIDs, use the URN form (urn:oid:(note: lowercase) and urn:uuid:). See http://www.ietf.org/rfc/rfc3001.txt and http://www.ietf.org/rfc/rfc4122.txt

This oid is used as an identifier II.root to indicate the the extension is an absolute URI (technically, an IRI). Typically, this is used for OIDs and GUIDs. Note that when this OID is used with OIDs and GUIDs, the II.extension should start with urn:oid or urn:uuid:

Note that this OID is created to aid with interconversion between CDA and FHIR - FHIR uses urn:ietf:rfc:3986 as equivalent to this OID. URIs as identifiers appear more commonly in FHIR.

This OID may also be used in CD.codeSystem.
