Original FreeMind File Format

The original FreeMind format was never described completely formally, but there is some documentation:

Note 
the above documentation is outdated in regard to elements introduced by Freeplane, like connector labels, attributes, scripts, user icons and (scalable) images embedded in the map.

Freeplane's version of it

The following schema takes the schema pointed at in the previous chapter and completes it with Freeplane specific extensions (in bold for easy identification):
