I'm about to write a blog about Kate on 5. In that context, I've quickly created the frameworks 5 diagram with TikZ (I'm very much addicted to that). Attached you can find the source code, along with the pdf file created by: pdflatex kf5.tex Feel free to put that into git, if you want. I've added a tier 0 already. There, Tier 0 is basically defined by everything that is a requirement to the other tiers. Greetings, Dominik
