@FinanceYF5: A team created an open-source knowledge graph covering everything a child should learn in elementary school. It includes 1,590 concepts and 3,221 connections across 8 subjects like math, science, computer science, and life skills, aligned with US NGSS, Common Core, and UK DfE curriculum standards.

A team has compiled all the content that elementary school children should learn into an open-source knowledge graph.
The scale includes 1,590 concepts and 3,221 connections, covering 8 subjects such as mathematics, science, computer science, and life skills, with each item aligned to the U.S. NGSS, Common Core, and UK DfE curriculum standards. 🧵 https://t.co/R0AZlEtWpY
Each concept is a structured JSON, annotated with the age range and evidence required to demonstrate mastery.
Each prerequisite relationship is labeled as either hard or soft dependency, with a reason given — essentially a directed acyclic graph that can compute learning paths.
The license is divided into two parts:
- Database structure: ODbL 1.0, derivative databases must remain open source;
- Content: CC BY-SA 4.0, attribution + share-alike. You can use it for commercial products without open-sourcing your own product, but you must contribute improvements to the graph itself back.
The team says that after the release of Marble Curriculum, it received a lot of feedback, and they decided to open-source it. The main builder is Guillaume Boni.
Their assessment is that education plus AI is one of the hardest and most important problems of the next decade.
If you are building in the education field, this open-source graph is worth a look. How would you use this computable curriculum?

@Ryrenz: A children's education company has open-sourced its entire internal elementary school knowledge graph. The project is called os-taxonomy, essentially laying bare "what a child should learn, and in what order" for everyone to use. The os-taxonomy repo was only created this past July and now has 5,881 stars and 986 forks…
Marble has fully open-sourced its internal elementary school knowledge graph, os-taxonomy, containing 1,591 fine-grained knowledge points and 3,225 prerequisite dependencies forming a directed acyclic graph, covering 8 subjects and aligned with curriculum standards such as NGSS and Common Core. The license permits both research and commercial use. The project has quickly garnered 5,881 stars and 986 forks since launch, providing education products with a ready-to-reuse foundation of prerequisite relationships.
@0xCheshire: The ultimate underlying cheat for AI education has arrived! This person just fully open-sourced the entire elementary school super knowledge graph. It deconstructs 8 major subjects into 1,590 core concepts and 3,221 logical links, precisely aligned with top-tier British and American educational standards. Highly structured JSON format with clear weights and evaluation criteria. You can make the algorithm…
A developer has open-sourced a super knowledge graph covering 8 elementary school subjects, containing 1,590 core concepts and 3,221 logical links, aligned with British and American educational standards. It can be used by algorithms to generate personalized learning paths.
@nash_su: Knowledge graph visualization with a time dimension! This display form is amazing. Traditional knowledge graph visualization cannot show timeline information. This form introduces a time dimension, which is very valuable. This is everything for elementary school students: 1,590 concepts. 3,221 connections, spanning 8 subjects, from math and science to computing and…
Introduces a knowledge graph visualization method with a time dimension, used to display 1,590 concepts and 3,221 connections learned by elementary school students, spanning 8 subjects, effectively compensating for the inability of traditional knowledge graphs to show timeline information.
@hassanyehiaa: I've received a lot of direct messages these past two days, and many tutors and teachers have offered suggestions — I'm truly grateful. I've been continuously improving the knowledge graph content, and based on everyone's feedback, I've increased the difficulty levels of the question banks as well as expanded the number of questions. Details are as follows: Difficulty tiers: Questions for each knowledge point are divided into three tiers — Basic, Advanced, and Extension. Diagnostic order: Present the Advanced question first; if answered correctly, use an Extension question to confirm mastery. If answered incorrectly, follow up with a Basic question; if still incorrect, trace back to related knowledge points from earlier grades, with the prerequisite knowledge highlighted on the interface.
The author updated the open-source K-12 knowledge graph project cn-math-taxonomy, adding three difficulty tiers (Basic/Advanced/Extension) of questions for each knowledge point, and improving the adaptive diagnostic order and prerequisite backtracking logic. The project covers math, Chinese, science, English, and physics, and provides an online diagnostic tool, though the author notes it is an AI-generated draft that still awaits teacher review.
@jinglian: The "K-12 Knowledge Graph" open-source project I've recommended twice in a row has now surpassed 5000+ Stars! A true open-source gem for self-study and tutoring.
