Human-readable schema reference

Browse root fields and reusable definitions, follow linked $ref types, and expand or collapse every object, array, and schema composition.

Important: A file validating against a schema is not necessarily technically complete or engineering-verified. MatJSON defines separate conformance and review levels.

Canonical `$id` policy

Each published schema uses an immutable, versioned URL as its canonical `$id`. The `latest` path is provided only as a convenience and returns the same current versioned schema.

Working-draft status

All five published profiles are substantive working drafts intended for design, implementation, and interoperability testing. They are not final standards, and schema validity does not by itself establish engineering verification.
