Machine Readable Concept Model

Snow Owl supports the Machine Readable Concept Model (MRCM), which represents the SNOMED CT Concept Model rules in a computer readable form to test that concept definitions and expressions comply with the rules.
A human readable version of the SNOMED CT Concept Model is available in the SNOMED CT Editorial Guide.
The MRCM may be used for a variety of purposes, including authoring, validation, and terminology binding to support semantic interoperability.
An MRCM contains a set of domains and a set of attributes that may be applied to one or more domains. The MRCM specifies the cardinality and valid range of each attribute and indicates whether or not the attribute should be grouped.
