H-MCMS: Universal Cataloging & Portal API

Zero-code polymorphic cataloging engine supporting fine art, postal philately, palace codicology, and contemporary crafts with an open Headless GraphQL/REST API.

H-MCMS eliminates rigid database schemas by offering a dynamic archetype engine. Curators instantly switch between sculpture casting schemas, philatelic perforation grids, royal codicological bindings, and fragile glass optical parameters without requiring database migrations.
