CompressionAlgorithm

Properties

This code system defines the following properties for its concepts

Code

URI

Type

Description

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

Coding

Inverse of Specializes. Only included as a derived relationship.

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

string

Haven't a clue!

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 heirarchy:

Code	Display	Definition	internalId	howApplies	status
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
