aigclink · x · 2026-10-17
Marble open-sourced os-taxonomy on GitHub: an open, structured taxonomy of elementary education decomposed into fine-grained micro-topics wired into a prerequisite graph and aligned to national curriculum standards. Version v1 ships 1,590 topics and 3,221 prerequisite edges across 8 subjects, under ODbL-1.0 / CC-BY-SA-4.0 licenses.
The repo includes data, schema and scripts, plus an interactive visualization at withmarble.com/curriculum where each dot is a micro-topic colored by subject and positioned by age, letting you trace everything a learner must master before any concept. It has quickly reached 5k stars and 841 forks.
