One idea that I think would be neat would be to expand it beyond written texts. For example: https://chewydecimalsystem.org/

I am somewhat biased in this regard too though, while physical location has to be tied to a singular thing, with digital mapping tag systems, even better if they are scalable, make for much more accurate catalogs.

For example the arch wiki is a reference source, but of what info? Hierachical stacking helps but falls apart when now the gaming sections of the arch wiki can’t be found next to the Windows gaming sections because they are isolated by OS instead of by gaming, or you are digging through every OSs collection of gaming information when you do have an OS specific question.

Mermaid.js and UML has covered what I thought were some pretty complex systems diagrams myself
