Expansion based on CompressionAlgorithm v2.0.0 (CodeSystem)

All codes from system http://terminology.hl7.org/CodeSystem/v3-CompressionAlgorithm

BZbzipbzip-2 compression format. See \[http://www.bzip.org/\] for more information.
DFdeflateThe deflate compressed data format as specified in RFC 1951 \[http://www.ietf.org/rfc/rfc1951.txt\].
GZgzipA 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).
ZcompressOriginal UNIX compress algorithm and file format using the LZC algorithm (a variant of LZW). Patent encumbered and less efficient than deflate.
Z7Z77z compression file format. See \[http://www.7-zip.org/7z.html\] for more information.
ZLzlibA compressed data format that also uses the deflate algorithm. Specified as RFC 1950 \[http://www.ietf.org/rfc/rfc1952.txt\]

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
