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

Code | Display | Definition
oid | OID | An ISO object identifier; e.g. 1.2.3.4.5.
uuid | UUID | A universally unique identifier of the form a5afddf4-e880-459b-876e-e4591b0acc11.
uri | URI | A uniform resource identifier (ideally a URL - uniform resource locator); e.g. http://unitsofmeasure.org.
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 rdf.html#iri-stem for details on how this value may be used.
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
other | Other | Some other type of unique identifier; e.g. HL7-assigned reserved string such as LN for LOINC.
