Show HN: I made a mind map tool meant for large, detailed node hierarchies

Another hierarchical organizer: AGPL, desktop- and keyboard-oriented, highly efficient, I use every day because org-mode was more awkward to me: http://onemodel.org . (My progress has been slow lately but I have plans: feedback welcome, especially if on the mailing list.)

Anything can be nested anywhere, so I put effectively all my notes in it on everything. In college it would have been a huge help. It exports to text outlines (w/ or w/o legal numbering) which I've found useful when sharing info before the real sharing feature is implemented.

(The idea behind it is to reduce knowledge to an atomic level, as an object model: things we know have relationships to other concepts, can be expressed as measurements, etc. But it is cumbersome to create an object model anew, for every app. Right now, it is really good at supporting a big, efficient list of lists (based in postgresql), with attributes, and very minimal support for defining classes on the fly as a side-effect of use. But I really hope to be able to add anki-like (spaced repetition / flashcard-like) features, internal scripting, hosting, and secured sharing of info between instances, so it becomes like a wiki in convenience, but more efficient and computable rather than piles of words for everything).
