The FreeMind format is the one most commonly accepted for import and provided
for export by other mind mapping software.
However, there is more than one schema in regular use: The present 'live' version
of FreeMind (0.8.0) has a somewhat different schema from that of the Beta (0.9.0),
which is in wide use in the FreeMind community.
I am collecting information on which software that claims to export or import FreeMind
files works with which versions, and what the limitations of using non-supported
versions are. Please let Vic know if you can provide more information on FreeMind
versions supported by specific software.
