Type of compression algorithm used

This Code system is referenced in the content logical definition of the following value sets:


This code system defines the following properties for its concepts

SpecializesCodingThe 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.
GeneralizesCodingInverse of Specializes. Only included as a derived relationship.
internalIdhttp://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-idcodeThe internal identifier for the concept in the HL7 Access database repository.
howApplieshttp://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-how-appliesstringHaven't a clue!
statushttp://hl7.org/fhir/concept-properties#statuscodeDesignation of a concept's state. Normally is not populated unless the state is retired.


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

BZ bzipbzip-2 compression format. See \[http://www.bzip.org/\] for more information.23535active
DF deflateThe deflate compressed data format as specified in RFC 1951 \[http://www.ietf.org/rfc/rfc1951.txt\].10621mandatoryactive
GZ gzipA 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).10622otheractive
Z compressOriginal UNIX compress algorithm and file format using the LZC algorithm (a variant of LZW). Patent encumbered and less efficient than deflate.10624deprecatedactive
Z7 Z77z compression file format. See \[http://www.7-zip.org/7z.html\] for more information.23536active
ZL zlibA compressed data format that also uses the deflate algorithm. Specified as RFC 1950 \[http://www.ietf.org/rfc/rfc1952.txt\]10623otheractive
