What is a freemind map? What file format is this? Is it a file format browsers understand? Mantis supports inline display of common image formats but that's of course easy since browsers support displaying images.

freemind is an open source application that is used for mind mapping. Mind mapping is the process of brainstorming and mapping your ideas on a document that you can print, share with others, or generate documents from.

0007214 provides a patch for supporting mind map export functionality. It also refers to a mind map flash viewer support which can be used to implement this feature.

I would like to see this feature implemented in 1.2.0 as a plugin.

I use freemind map to do a sort of "rapid" study of client requirements to generate the relative issues, so if in a node of freemind map I insert the link to the issue in mantis you obtain the traceability issue/requirements.

For the map viewing it is possible to use java applet, but I think it is better the flash viewer (at minimum for spread's reasons).

Nice idea!

I've updated the freemind export & browser (0007214) to use the new plugin system since it seems to have been excluded from he core system: http://blog.teambits.de/2010/11/02/mantis-plugin-freemind-export-and-browser/

I did not test extensively yet, but for me it seems to work alright.
