Sure, glad it can be helpful.
These are the permanent notes that are linked to from all the others
Notes taken while reading books, for the most part. The date corresponds roughly to when I started reading them but it’s not very important.
Notes taken during recurring meetings. It’s useful to keep them in the same note because very often I want to quickly check what was said/agreed to on the previous meetings. Archived once the meeting is no longer taken. The date corresponds to the month I started the note, so that meeting names can be archived then reused without thinking too much about it. One-off meeting notes just go on the project note—if there is one—or else in the journal.
All notes referring to a project, including TODOs and meeting notes. Archived as soon as the project is done.
That’s just a org-journal directory, one file per day. That’s where I start taking notes if I don’t want to think where to put them.
This is the heart of my task management/org-agenda system. Most TODOs are entered here usually from org-capture or beorg on mobile, then I have a few ways to review/organize, archive them.
I also just started a who directory with one file per person. I’m just starting to slowly migrate an Evernote database with notes dating all the way back to the early 2000’s (when I was using InfoSelect). The system there is very stable, but it’s not entirely settled how it will translate in org-mode.
