Maintaining SKOS vocabularies collaboratively is hard. RDF/turtle syntax intimidates domain experts. Manual validation is error-prone. Tracking changes and discussions scattered across emails is chaotic. Result? Many communities avoid creating controlled vocabularies altogether. We built an open-source toolkit that simplified the process: contributors edit terms in Excel spreadsheets, submit via GitHub pull requests, and automated workflows handle everything else – SKOS conversion, SHACL validation, documentation generation, and publishing with persistent URIs and content negotiation. Why Excel? Familiar to everyone. Why GitHub? It provides version control with complete history tracking, structured discussions via issues/PRs, free hosting, automatic Zenodo publishing and increasingly, built-in AI assistance for contributors and maintainers. The toolkit (Python package + repository template) is domain-agnostic – originally developed for a catalysis vocabulary, but reusable by any community.
