- Include these codes as defined in
http://terminology.hl7.org/CodeSystem/v3-CompressionAlgorithm version 2.1.1| Code | Display | Definition |
| DF | deflate | The deflate compressed data format as specified in RFC 1951 \[http://www.ietf.org/rfc/rfc1951.txt\]. |
| 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). |
| ZL | zlib | A compressed data format that also uses the deflate algorithm. Specified as RFC 1950 \[http://www.ietf.org/rfc/rfc1952.txt\] |
| Z | compress | Original UNIX compress algorithm and file format using the LZC algorithm (a variant of LZW). Patent encumbered and less efficient than deflate. |
