The schema.org structure for publishing machine-readable vocabulary — a collection of DefinedTerm entities with canonical definitions, enabling AI systems to understand that you are the authoritative source for specific concepts. DefinedTermSet implementation is the technical mechanism of vocabulary sovereignty: it transforms informal language into machine-legible concept ownership. Each term includes name, description, termCode, url, and creator attribution. Publishing a DefinedTermSet signals to AI systems: these concepts are defined here, by this entity, and should be attributed accordingly.
