Concepts

This case-sensitive code system http://terminology.hl7.org/v2plusvocab/CodeSystem/UniversalIdTypeV110 defines the following codes:

CodeDisplayDefinitionversion introducedcommentDeutsch (German, de)
DNS Domain Name System An Internet dotted name. Either in ASCII or as integers 2.3 An Internet host name, in accordance with RFC 1035; or an IP address. Either in ASCII or as integers, with periods between components (“dotted” notation). Internet-Adresse
GUID globally unique identifier Same as UUID. 2.3 Same as UUID.Retained for backward compatibility only as of v2.7; use UUID instead GUID
HCD CEN Healthcare Coding Identifier The CEN Healthcare Coding Scheme Designator. (Identifiers used in DICOM follow this assignment scheme.) 2.3 The CEN Healthcare Coding Scheme Designator. Retained for backward compatibility only as of v2.7; does not identify Assigning Authorities
HL7 HL7 registration schemes Reserved for future HL7 registration schemes 2.3 Retained for backward compatibility only as of v2.7; HL7 assigns ISO OIDs for Assigning Authorities für HL7 reserviert
ISO ISO Object Identifier An International Standards Organization Object Identifier 2.3 An International Standards Organization Object Identifier (OID), in accordance with ISO/IEC 8824. Formatted as decimal digits separated by periods; recommended limit of 64 characters ISO-ID
L Local These are reserved for locally defined coding schemes. 2.3 Locally defined coding entity identifier.Retained for backward compatibility only as of v 2.8 reserviert für lokale Tabellen
M Local These are reserved for locally defined coding schemes. 2.3 Locally defined coding entity identifier.Retained for backward compatibility only as of v 2.8 reserviert für lokale Tabellen
N Local These are reserved for locally defined coding schemes. 2.3 Locally defined coding entity identifier.Retained for backward compatibility only as of v 2.8 reserviert für lokale Tabellen
Random Random Usually a base64 encoded string of random bits. 2.3 Usually a base64 encoded string of random bits.Retained for backward compatibility only as of v2.7; equivalent to a locally defined entity identifier scheme; use L. M, or N instead. Note: Random IDs are typically used for instance identifiers, rather than an identifier of an Assigning Authority that issues instance identifiers beliebig
URI Uniform Resource Identifier Uniform Resource Identifier 2.5 URI
UUID Universal Unique Identifier The DCE Universal Unique Identifier 2.3 The DCE Universal Unique Identifier, in accordance with RFC 4122. Recommended format is 32 hexadecimal digits separated by hyphens, in the digit grouping 8-4-4-4-12 UUID
x400 X.400 MHS identifier An X.400 MHS format identifier 2.3 Recommended format is in accordance with RFC 1649 X.400
x500 X500 directory Name An X.500 directory name 2.3 X.500 Verzeichnis­name
