Welcome, @maparent!
What kind of alternatives are you looking for?
I find the 3 different layers describe in context with hyperknowlege quite interesting. Could you maybe write/post a bit about those here as they could an interesting concept and vocabulary for multiple projects and people could easier engage directly with the details of your projects?
otherwise, I would also recommend to you to maybe check out our SSNA stuff, and how we are exploring different conversation and sensemaking layers with that, e.g. here: NGI Ethnography Preliminary Findings - October 2020
