Properties

This code system defines the following properties for its concepts

NameCodeURITypeDescription
Specializes Specializes Coding The child code is a more narrow version of the concept represented by the parent code. I.e. Every child concept is also a valid parent concept. Used to allow determination of subsumption. Must be transitive, irreflexive, antisymmetric.
Generalizes Generalizes Coding Inverse of Specializes. Only included as a derived relationship.
internalId internalId http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-id code The internal identifier for the concept in the HL7 Access database repository.
howApplies howApplies http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-how-applies string Haven't a clue!
Status status http://hl7.org/fhir/concept-properties#status code Designation of a concept's state. Normally is not populated unless the state is retired.

Concepts

This case-sensitive code system http://terminology.hl7.org/CodeSystem/v3-CompressionAlgorithm defines the following codes in a Is-A hierarchy:

CodeDisplayDefinitioninternalIdhowAppliesStatus
BZ bzip bzip-2 compression format. See \[http://www.bzip.org/\] for more information. 23535 active
DF deflate The deflate compressed data format as specified in RFC 1951 \[http://www.ietf.org/rfc/rfc1951.txt\]. 10621 mandatory active
GZ gzip A compressed data format that is compatible with the widely used GZIP utility as specified in RFC 1952 \[http://www.ietf.org/rfc/rfc1952.txt\] (uses the deflate algorithm). 10622 other active
Z compress Original UNIX compress algorithm and file format using the LZC algorithm (a variant of LZW). Patent encumbered and less efficient than deflate. 10624 deprecated active
Z7 Z7 7z compression file format. See \[http://www.7-zip.org/7z.html\] for more information. 23536 active
ZL zlib A compressed data format that also uses the deflate algorithm. Specified as RFC 1950 \[http://www.ietf.org/rfc/rfc1952.txt\] 10623 other active
