Properties

This code system defines the following properties for its concepts

Name | Code | URI | Type | Description
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:

Code | Display | Definition | howApplies | Status
BZ | bzip | bzip-2 compression format. See \[http://www.bzip.org/\] for more information. | | active
DF | deflate | The deflate compressed data format as specified in RFC 1951 \[http://www.ietf.org/rfc/rfc1951.txt\]. | 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). | 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. | deprecated | active
Z7 | Z7 | 7z compression file format. See \[http://www.7-zip.org/7z.html\] for more information. | | active
ZL | zlib | A compressed data format that also uses the deflate algorithm. Specified as RFC 1950 \[http://www.ietf.org/rfc/rfc1952.txt\] | other | active
