Machine-readable structure for declaring a canonical URL and optional canonicalization context.
Namespace reference
See the conceptual definition of canonical URL representation, including distinction from url, id, authority, and trust.
Schema notes
The canonical MSP-1 v1.0.1 form for canonical is an object with url as the required field.
canonical is related to url, id, authority, and trust, but it is not interchangeable with them. canonical identifies the preferred URL representation; it does not establish authority, trust, or correctness by itself.
