This repository maintains the curated metadata for GitHub Topics and Collections. It is not a running application but a structured dataset of topic definitions (with aliases, related topics, logos, Wikipedia links) and curated repository lists (collections). The actual 'application' code is a suite of Ruby tests (RSpec/Minimatch) that validate metadata correctness, image dimensions, link validity, and API referential integrity via batched GraphQL queries. CI/CD workflows enforce contribution guidelines, auto-correct renamed repos, and deploy a Jekyll-generated JSON feed. While primarily a data repository, it exhibits strong software engineering practices in validation, caching, and automation. The content is community-curated and licensed under CC-BY 4.0.
