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


SpecializesThe 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.Coding
GeneralizesInverse of Specializes. Only included as a derived relationship.Coding
internalIdhttp://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-idThe internal identifier for the concept in the HL7 Access database repository.code

statushttp://hl7.org/fhir/concept-properties#statusDesignation of a concept's state. Normally is not populated unless the state is retired.code

This code system http://terminology.hl7.org/CodeSystem/v3-CompressionAlgorithm defines the following codes:

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
