1.23.1.0 Named Systems List

The URIs defined on this page are available as a value set (XML or JSON).

1.23.1.0.1 Known Code Systems

The following names (URIs) may be used in the system element of the Coding data type. If a URI is defined here, it SHALL be used in preference to any other identifying mechanisms. If a code system is not listed here, the correct URI may be determined by working through the following list, in order:

  • the HL7 OID Registry
  • the documentation associated with the code system
  • consulting the owner of the code system
  • asking on the HL7 vocabulary mailing list

1.23.1.0.2 Known Identifier Systems

The following names (URIs) may be used in the system element of the Identifier data type. If a URI is defined here, it SHALL be used in preference to any other identifying mechanisms. If an identifier system is not listed here, the correct URI may be determined by working through the following list, in order:

  • the HL7 OID Registry
  • the documentation associated with the identifier
  • consulting the owner of the identifier
  • asking on the HL7 vocabulary mailing list
identifier URI Comment
URIs (W3C): when the identifier is a URI urn:ietf:rfc:3986 As defined by RFC 3986 (with many schemes defined in many RFCs). OIDs and UUIDs are represented in their URN form (urn:oid: and urn:uuid: - plain oid: and uuid: are not used). Note that UUIDs are always lowercase in a IRI

Driver's licenses are often recorded without recording which authority issued the license. In these cases, use the general identifier http://hl7.org/fhir/drivers-license

Important Note: This list of names is incomplete and subject to change. Some values may be dropped and others will likely be added in the coming months as HL7 institutes formal processes around URIs in vocabulary.

Note that some of the URNs in this list follow the URN specification in RFC 5141 for referring to standards published by ISO, such as urn:std:iso:11073:10101. Where ISO standards define codes with meanings, and there is no entry in the list above, and they are not registered in the HL7 OID registry, the default URN for the code system is that defined by the RFC 5141.
