The Manufacturing Common Data Model is a ___domain-oriented schema for standardizing data structures. It harmonizes shop-floor events and enterprise records by mapping equipment, material, batch and order entities to the hierarchical object classes defined in [[ISA-95]] and, for production processes, [[ISA-88]].<ref>[https://www.isa.org/isa95 ISA-95: Enterprise–Control System Integration – International Society of Automation]</ref>
Each ___domain (Production, Quality, Maintenance, Supply Chain) owns its own CDM; the structure of every table and field is enforced through data contracts, which are validated at the plant’s Edge Intelligence Hub before data is published to the Unified Namespace and persisted in a governed lakehouse layer.<ref>[https://umda.info/framework-details/#cdm UMDA Specification]</ref>
By standardizing attribute names, units of measure (e.g. SI, ISA-100), and reference codes such as [[GS1]] GTIN, the model allows MQTT / OPC UA telemetry to be joined consistently with MES, LIMS, CMMS, and ERP data, enabling AI agents to query any site with uniform semantics while maintaining full lineage for [[Title 21 CFR Part 11]] and EU-GMP Annex 11 compliance.<ref>[https://www.gmp-compliance.org/gmp-news/eu-gmp-annex-11-update EU GMP Annex 11 – Computerized Systems]</ref>
