Hi Simon, welcome to the community. Feel free to DM me if you’d like to setup a call to share ideas.

We’ve also had some good discussions on Tinderbox workflows, see: An end-to-end Professional, Academic, & Personal 5Cs of Knowledge Management Workflow (Updated)
A while back there was a great exchange around different workflows that people had, but I can’t seem to find post. Maybe someone can help.
Since you’re interested in Knowledge Graphs, you may enjoy this meetup: Tinderbox Meetup Saturday 16 September Video: Knowledge Synthesis and Discourse Graphs with Joel Chan.
