Relationship between CG and Schema.org

The Schema.org Community Group was created to serve as the public discussion forum for the schema.org project.

W3C Community Groups do not create W3C Recommendations, but provide a less formal environment for discussion and collaboration. External projects (such as Schema.org) often use these groups too, and have their own rules. Schema.org is not a W3C initiative, and is not controlled by this Community Group.

This is a group about Schema.org, which has at times played various roles in the life of the project and the lifecycle of its schemas.

As of 2026 Schema.org is being run directly by Google in the style of other Google-led collaborative opensource initiatives such as Chromium and Android. Ultimate control of the Schema.org project is grounded in its domain name, which is owned by Google.

Google staff and other collaborators continue to develop the project via its Github repository, and manage its expansion and maintenance there.

Please do not use this Community Group as a mechanism for reporting bugs and problems with specific search engine’s products and features – company-specific sites are more effective for these topics. As ever, it is usually counterproductive to advocate for new terms to be added to schema.org without a motivating consuming application.

Schema.org’s releases page is the best guide to its evolution over time, and to the kinds of changes its maintainers prioritise. Their developers page gives a number of ways to use its schemas in machine-readable (RDF-based) dumps. The project terms of service currently declares a CC BY-SA license (“If you remix, transform, or build upon the material, you must distribute your contributions under the same license as the original.”). From 2011-2026 the project has not collected CLAs or copyright re-assignment claims from its contributors, or provided guidance on how to interpret these rules for use in markup, corporate Knowledge Graphs, schema mappings etc. See the Schema.org site and github for information about the upstream schemas and contributing parties from which various parts of schema.org were developed.
