A registry record can identify a standards-derived MatJSON package without publicly redistributing the package itself. Metadata can include source edition, profile, extraction scope, review status, technical verifier, rights status, and authorized access location.
Access policy
Rights-controlled data: The public starter site does not bundle the draft API, ASME, AMPP/NACE, ASTM, or ISO rule libraries created during development. Publication requires an explicit rights and licensing decision.
