My Brainstorm 🧠 ⚡️ instance uses its own custom coded GrapeRank calculator. ManiMe and I were working on integrating his above repo earlier this year, didn’t quite completed the process. And yup, Brainstorm uses Vitor’s NIP to export scores. ManiMe your GrapeRank calculator repo is used by grapevine.my, is it not? Part of our goal when ManiMe made those repos was to experiment with separating the GrapeRank algo into modules. In particular, separation of the interpretation module (ingest raw data like kind 3 or 1984 events) from the calculation module (mostly weighted averages). Still needs more R&D. There will by design be lots of distinct interpretation modules. In principle a single calculation engine should have wide applicability, but I’m not sure yet to what extent different teams may want to fork and customize the calculation engine. My calculator module has a few small tweaks that I think aren’t in ManiMe’s calculator.
