Tool Open source
An open, machine-readable taxonomy of learning across the primary and elementary years, produced by Marble. It represents fine-grained micro-topics as nodes in a prerequisite graph, with each topic containing a plain-language description, subject and domain, conceptual or procedural type, approximate age range, mastery evidence, assessment prompt, and links to source curriculum standards such as NGSS, Common Core, and the UK National Curriculum. Dependency edges identify hard or soft prerequisites and include reasons; the dataset also provides parent-friendly domain summaries. The JSON files include topics, dependencies, curriculum standards, domain clusters, and a manifest with counts and checksums. The repository describes it as pure data with no runtime or dependencies, and provides an interactive curriculum explorer at withmarble.com/curriculum.
