[O] org-mode for knowledge management

[Louis]

Hi all,
I've been using org-mode for a variety of purposes for a few years. I find 
that it suffers from the same problem that other such tools do. The 
problem is me. I can't remember week to week how I may have classified 
some scrap of information. Did I drop it into notes/someproduct.org or was 
it procedures/someprocess.org?

While working through this, I've used #+INDEX: Topic!subtopic which helps 
but is not sufficiently granular.

I'm thinking about approaches using properties or drawers. Has any of you 
done something like this, or done something similar that I've not 
considered?


Thanks in advance,

Your rapidly graying, Louis
