I find that #logseq really fits my note-taking needs well.
My notes are not a complete mess, but they do exhibit the characteristic of being... *eventually consist*.
I like to take notes of any shape, in any state. A note is my way of parking a piece of information so I can get on with my day; they don't tend to look like a private encyclopedia... at first!
It is also imperative that the note-taking software is #localfirst and #opensource. Oh and it doesn't hurt that it's written in #Clojure.
Since you are into RDF, do you know that you can export a portion of your Logseq graph as RDF? Here there is the script:

Ha, nice that they are taking inspiration from Tana's Supertags™. I currently use "Powertags" plugin that imitate it in Logseq.
