I have attempted to address this in the vision & internal structure of a tool I wrote (AGPL): a work in progress which is planned to meet most of the requirements mentioned in the article. I wrote it (after trying org-mode, collapsible outlines in other tools, etc). It uses postgres, and I hope that "sharing" data exchange features between multiple instances are coming (though it already does export to org-mode-like text, to readable outlines in the latest dev code, and to html). The best code is that in github, though an older and useful downloadable .jar is available. Currently, it is keyboard and desktop-only (text-oriented). It also is the most efficient/effective thing I have found for organizing notes/lists/details of all kinds, and should be easy to learn to use, as all the essentials are on the screen. There is a tutorial. It makes an internal knowledge graph as one uses the product (stored in postgres, runs fast). It builds an object model on the fly as a side-effect of using the product, using relationships, numbers, etc as knowledge at an atomic level where words are secondary. The best info organizer (for my style at least) that I know of, though (so far) less feature-rich than many products. I hope the About page at that link explains the present and future well. (Part of the eventual purpose of the tool is to help individuals and mentors via maturity models that apply more generally to life before getting into any particular topic. That could easily be misunderstood, and there is more about that at the web site (below). Part of the idea is to help in the development/growth of self and others -- skills, knowledge, positive character traits, anything good -- in any area of life that one chooses, so we can have good goals instead of trying to make life seem fulfilling with empty searching for more pleasure/power/attention. And by marking things done or "archived", it also provides a journal feature or personal log, of entries created or archived in any date range (defaulting to "yesterday and so far, today", to help with daily standup reporting).) http://onemodel.org http://onemodel.org (And yes I plan to move to https fairly soon :) ...as well as adding anki-like and other features someday.) Candid feedback welcome, especially via the site (2 mailing lists; direct email in footer). Thanks.
