The SNOMED CT Machine Readable Concept Model Specification (MRCM) defines and describes the structural design of the SNOMED CT MRCM. The MRCM represents the concept model rules from the SNOMED CT Editorial Guide in a form that can be read and tested by a computer.
This specification defines a new MRCM format that is based on existing SNOMED CT files and standards. It uses the Expression Constraint Language to represent MRCM rules and the SNOMED CT Reference Set mechanism to provide a structural format with inbuilt versioning. This allows distribution of the MRCM using the standard RF2 reference set distribution files and the interpretation of MRCM rules using tools that already support the Expression Constraint Language.
