Property compression : Tv3Compression; (Read/Write)

Class Iv3ED

The compression algorithm, if any, used on the raw byte data.

If the attribute is null, the data is not compressed. Compression only applies to the binary form of the content.

If populated, the value of this attribute SHALL be taken from the HL7 CompressionAlgorithm code system.

Some compression formats allow multiple archive files to be embedded within a single compressed volume. Applications SHALL ensure that the decompressed form of the data conforms to the stated media type -- Possible compression types for content

cNull

cDF : Deflate : The deflate compressed data format as specified in IETF RFC 1951

cGZ : GZIP : A compressed data format that is compatible with the widely used GZIP utility as specified in IETF RFC 1952(uses the deflate algorithm)

cZL : ZLIB : A compressed data format that also uses the deflate algorithm. Specified as IETF RFC 1950

cZ : Compress : Original UNIX compress algorithm and file format using the LZC algorithm (a variant of LZW). Patent encumbered and less efficient than deflate

cBZ : BZIP : bzip-2 compression format. See [http://www.bzip.org/] for more information.

cZ7 : Z7 : 7z compression file format. See [http://www.7-zip.org/7z.html] for more information.
