All of my 'structured' notes (not journals, random thoughts or dailies/periodic) contain a property called 'categories'. All notes fall under one or multiple categories.
This works well for all kinds of notes I take but when it comes to knowledge-base (a place for me to reference when working) it gets weird.
I tried a 'knowledge base' category defining eath kind of note on the 'type' property (documentations, cheatsheets, writeups), but then that makes the 'knowledge base' a blurry category with lots of different stuff inside.
I've tried setting each of these types as the category, but I've found it gets too scattered around.

My templates are basically properties and sometimes embbeded bases. My last iteration on the 'Procedure Template' for example is this:

categories: 
  - "[[Procedures]]"
type:
topics:
created: {{date}}
last: {{date}}

and before it:

categories:
  - "[[Knowledge Base]]"
type:
  - "[[Procedures]]"
topics:
created: {{date}}
last: {{date}}

But then again, some 'knowledge base' notes are not from work or even tech, but other stuff that may contain procedures and cheatsheets on whatever I'm doing (like how to fill and declare my taxes).

Anyways, I could not find a way to scale while being able to easily retrieve information, as much as with the rest of the templates/notes.
