examplesrich

Examplesrich is a community-driven online platform that curates and hosts example-rich content across disciplines, with an emphasis on practical, annotated examples that illustrate concepts and workflows. The site collects code samples, mathematical demonstrations, problem sets, and instructional narratives, organizing them into topic collections and bundles.

Founded in 2020 by educators, software developers, and curriculum designers, Examplesrich started as an open-submission project with permissive licensing and lightweight moderation. It has since grown through partnerships with schools and open educational resources initiatives, expanding to tutorials, notebooks, and interactive demos.

Its features include a robust search and tagging system, versioned example packs, and support for multiple formats such as Markdown, HTML, Jupyter notebooks, and code fragments. The platform offers an API, embeddable content, and guidance on attribution to promote reuse while respecting authorship.

Content covers computer science, mathematics, data science, science education, and humanities. The project emphasizes reproducibility and step-by-step demonstrations, often pairing explanations with runnable artifacts. Governance is community-driven, with a moderation team, a reputation system, and periodic policy reviews. Licensing typically uses Creative Commons or permissive software licenses.

Users report that Examplesrich supports learning and teaching by providing accessible, real-world illustrations. Critics note challenges in maintaining quality and consistency at scale, as well as licensing ambiguity in some submissions. Ongoing efforts focus on stronger review workflows, clearer licensing guidance, and expanded multilingual content.
