I keep wanting to do this thing

I've read of Zettelkasten and it mostly makes sense.
Also I take a fair bunch of notes, either manually or 'things that I might need later on'.
I like bullet journaling; I like that it is freeform and that I can do it 'now' and perfect it later. Stopping to think is what makes me stop. I get bullet journaling done, but not Zettelkasten.

It's because I need a perfect system, see.
For the perfect recall. And the perfect arrangement for the perfect overview.
But even if I get that - I won't be able to use it because there will be something amiss, or the project might die, or go proprietary - and so I need it to store things in a simple way that other perfect systems can understand and which is also easy to jot down manually because them perfect systems don't come along so often.

As far as I know the only things needed would be an atomic note, a unique id for that note, and references to sources - plus for my own reasons of perfectedness, some optional freeform hierarchical tags.

Since I know this doesn't exist, cannot exist, I didn't go look for it; there are rumours of some sort of open source notetaking system which -might- be perfect but since I know it cannot be, I never went looking.. :>
