Generated Narrative: CodeSystem namingsystem-identifier-type

This case-sensitive code system http://hl7.org/fhir/namingsystem-identifier-type defines the following codes:

CodeDisplayDefinition
oid OID

An ISO object identifier; e.g. 1.2.3.4.5.

\n
uuid UUID

A universally unique identifier of the form a5afddf4-e880-459b-876e-e4591b0acc11.

\n
uri URI

A uniform resource identifier (ideally a URL - uniform resource locator); e.g. http://unitsofmeasure.org.

\n
iri-stem IRI stem

An IRI string that can be prepended to the code to obtain a concept IRI for RDF applications. This should be a valid, absolute IRI as defined in RFC 3987. See the RDF spec for details on how this value may be used.

\n
v2csmnemonic V2CSMNemonic

A short string published by HL7 for use in the V2 family of standsrds to idenfify a code system in the V12 coded data types CWE, CNE, and CF. The code values are also published by HL7 at http://www.hl7.org/Special/committees/vocab/table_0396/index.cfm

\n
other Other

Some other type of unique identifier; e.g. HL7-assigned reserved string such as LN for LOINC.
