Categories database

From WhyNotWiki

This is an important table! Almost all of my other tables will link to it!

[edit] One ontology to rule them all

I want to have one ontology to rule them all. By "them all", I don't mean everyone else in the world -- I expect there would still be a need, most of the time, for each individual person / organization to have their own ontology / category tree.

What I mean by this is simply that once a person creates an ontology for themselves once -- their abstract representation of the world they live in -- they would never have to do it again. Everywhere that needs tags/categories/an ontology would share the same one. All applications would tie into this same table/database so you wouldn't have to recreate your nice organization in every application that you use.

In other words, don't repeat yourself!

Examples...

Your wiki would use this database for organizing / classifying content
Your book collection would tie into this database for categorizing/labeling books with topics
Your to-do lists would use it.
Your file system would mirror it / synchronize with it (although it probably couldn't tie into it natively)
You would use the same list/tree of projects across your to-do list, your wiki, your blog, your file system (where you actually do your work/development on these projects), your password manager, etc., etc. They would all be parallel; they would all be in sync...
