It cannot contain active or executable content. The SOSI format does not provide privacy or integrity protection. If such protections are needed they must be provided externally. Interoperability considerations: There are no relevant interoperability issues. SOSI files are plain text files using various ASCII based character sets. The character set and encoding used in the file is specified using the ..TEGNSETT statement inside the file, and there is a limited set of charset names permitted (ANSI, DECN7, DOSN8, ISO8859-1, ISO8859-10, ND7 and UTF-8). New SOSI files should use "UTF-8". Published specification: Information about the SOSI format can be found in English from https://en.wikipedia.org/wiki/SOSI. The specification is available in Norwegian from the Norwegian mapping authority using https://www.kartverket.no/geodataarbeid/Standarder/SOSI/. Applications which use this media: The SOSI format was designed to be used in Norway to store and exchange digital vector based geo-spatial information. It is supported by several map related programs and libraries. Fragment identifier considerations: Not applicable. Restrictions on usage: There are no restriction on usage. Additional information: 1. Deprecated alias names for this type: none known 2. Magic number(s): See https://github.com/file/file/blob/master/magic/Magdir/sosi 3. File extension(s): sos 4. Macintosh file type code: none known 5. Object Identifiers: none known General Comments: SOSI is short for Samordnet Opplegg for Stedfestet Informasjon (literally "Coordinated Approach for Spatial Information", but more commonly expanded in English to Systematic Organization of Spatial Information). Person to contact for further information: 1. Name: Petter Reinholdtsen 2. Email: pere-iana&hungry.com Intended usage: Common The SOSI format is in regular use in Norway.
