Full Schema Hierarchy

Browse every schema.org type: what it inherits from, what inherits from it, and every property it accepts.

Built from schema.org's own machine-readable release -- 939 types and 1538 properties, version 30.1 -- and served from a committed copy, so it works whether or not schema.org is reachable. Each property is shown with the type it was declared on, which is the part that is hard to see on the official hierarchy page.

About this validation

Browses the schema.org type hierarchy from a committed copy of schema.org's own machine-readable release: supertypes, subtypes, and the properties a type accepts including everything it inherits.

Rules reviewed:

SEOTechTests methodology: Serves schema.org's type hierarchy from a copy of its own machine-readable release that is generated by a script in this repository and committed, so the page never depends on schema.org being reachable. Supertypes are flattened breadth-first, and the property list for a type is everything declared on it plus everything inherited.

Standards and vendor-documented behavior can change. This reflects the source as last reviewed above, not a permanent guarantee.

FAQ

Where does this hierarchy come from?

From schema.org's published machine-readable vocabulary, condensed to the type and property relations and committed to this site. The release version it was built from is shown with the results.[1, 2]

Why does a type list properties it does not declare?

Because it inherits them. Every type ultimately descends from Thing, so name, url, description and image are available everywhere without being declared on each type.[1]

What do pending and attic mean next to a type?

schema.org keeps proposed terms in a pending area before they join the core vocabulary, and moves retired ones to an attic so old markup still resolves. A term in either is real, but not part of the core vocabulary.[1]
