So what is the organization of your notes?

I would think that to collect knowledge about the world you would (ideally) need to have an ontological model of what are the categories of things we can talk about, and how those categories are connected to each other.

Creating such a model even if only in your head means organizing the knowledge we have and collect, and is not a trivial thing to accomplish.

Or does it not matter with Zettelkasten?
