## Intergeo Common File Format Symbols

This is the commented list of the Intergeo File Format symbols. This page was previously located at http://intern.inter2geo.eu/node/366, but it was abandoned as it is not publicly accessible. The Intergeo File Format is described here.

The XML-schema of the file format can be found here.

An XML file that summarizes the symbols that are used in the XML-schema can be found here.
