Welcome to the FOSS Foundations Metadata directory! We are eager to collaborate with academic researchers and open source practitioners alike on curating rich metadata about the many excellent non-profit Foundations that either host or help open source projects succeed.


Read more about our data philosophy.

  • Store metadata about Foundations in _foundations/ frontmatter, parseable as YAML/JSON.
    • File per foundation makes PRs simple to manage for anyone.
    • Frontmatter can be exposed by OpenAPI for programmatic access.
    • Jekyll turns foundation data in to human-readable websites automatically.
    • OpenAPI and GitHub Actions tooling can ensure linting, updates keep data clean.
  • Using flat files and GitHub Pages means zero maintenance.
  • Markdown body can be used for additional, unstructured data or descriptions.
  • Use common human-findable identifier strings to tie in sponsorship and other models.


  • Create a rich metadata directory about nonprofit open source organizations, including financial, sponsorship and other data.
  • Data is easy to consume in multiple ways that are reliable.
  • Website and any tooling are zero/low maintenance.
  • Build simple PR-driven data submission that prevents errors.
  • Attract multiple contributors that create community governance.


  • Tracking commercial entities.
  • Tracking non-entity projects; i.e. open source projects without legal entities.
  • Fancy features, UI, or hard to maintain visualizations.
  • Volunteers are welcomed to help turn non-goals into goals!
