Idea Management/Navigation Software?

psychonaut asks: "My work involves a lot of research and writing, and I often find myself jotting down brief notes on scraps of paper, in text files, in the margin of books, etc. The idea is to later use these ideas as the basis for various papers or even books I plan to write. However, because I have no central repository for all these ideas, finding long-forgotten thoughts and citations months after I've recorded them becomes a nightmare. Can anyone recommend an open source knowledge management, visualization, and navigation software I could use to bring together and classify all these disjointed ideas?"

"The system should be hypertext-based, allowing explicit links between nodes, but it would be nice if it could also derive some relations on its own. Having built-in support for referencing web links, printed publications (BibTeX integration?), and arbitrary files would be great. Text-based and perhaps also non-text-based searching capabilities (e.g., graphical visualization of node relationships) would also be very useful.

I've looked at some wiki systems but the choices seem overwhelming, and most of them are geared towards collaborative rather than individual work. Is there some wiki or database system that does what I need, or should I be looking for something in an entirely different paradigm?"

It's not open source, and you do have to sign up to download it (just username and email, I think... and I've been on their list for years and only get maybe 2 emails a year from them)... but it is free and it's a pretty nifty piece of software, allowing you to make large webs of thoughts, relate any node to any other node, link files & emails, etc.

If you're running Windows, it's at least worth checking out. http://www.thebrain.com

Why doesn't the Open Source community come up with a common XML foundation for information organization and design toward it?

Seriously, by starting with VERY BASIC meta tags (NAME, KEYWORD, DESCRIPTION) we could exponentially expand the productivity of OpenOffice, etc...

The KEY (no pun intended), however, is going to be linking these features among different apps. I can't even count how many times I've done a "locate project | grep png" and NEVER found the image that I was looking for.

Unity is key...

I use Memo Plus on the Palm, which is merely a hierarchical notepad.

I have things sorted into a hierarchy that works for me.

But oh, how I would love a cross-platform product that offered deep integration with email, address book, bookmarks, calendar, and random notes, with multiple hierarchical and/or directed graph maps, and good search capabilities. In my fantasy world, it'd run on my PC and on my Kyocera smart phone, and would be compatible with stuff on both ends: Firefox, Thunderbird, the Palm address book, etc. If I didn't have a job, that's what I'd be building right now...
