withmarbleapp/os-taxonomy
An open dataset from Marble mapping what children learn in primary/elementary school: 1,590 fine-grained micro-topics across 8 subjects, connected by 3,221 prerequisite edges into a directed graph, and aligned to standards like Common Core, NGSS, and the UK National Curriculum. Shipped as plain JSON with schemas, plus an interactive 3D visualization.
Why now: Notable for being an unusually structured, prerequisite-linked open curriculum graph — most curriculum data is flat standards lists or locked inside products; fresh release of v1 with an eye-catching 3D graph visualization.
Who it is for: Ed-tech developers, learning scientists, curriculum designers, and parents/builders building tutoring or adaptive-learning tools.
