Security considerations : There exist no security risks concerning GEONExT files. The media type does not contain executable content. It is just a compressed XML based description of a mathematical/geometric construction. This construction can be opened using the Java software GEONExT. The content does not need privacy or integrity services. Interoperability considerations : Files are in XML structure (ASCII with Java unicode encoding). Files can be compressed using the gzip algorithm and base 64 encoded. Published specification : File specification is published in "Carsten Miller: Entwicklung dynamischer Arbeitsblätter und ihre Realisierung für den Mathematikunterricht", ISBN 3-89963-060-2 Applications which use this media : GEONExT, JSXGraph Additional information : 1. Magic number(s) : NOT USED 2. File extension(s) : gxt 3. Macintosh file type code : NOT USED 4. Object Identifiers: NOT USED Person to contact for further information : 1. Name : Matthias Ehmann 2.
