This specification defines a standard format of URIs for identifying various SNOMED CT artifacts, including SNOMED CT components, modules and editions.
This specification defines a formal syntax for representing sets of clinical meanings using SNOMED CT expression constraints. Expression constraints are used for a range of purposes, including restricting the valid values in a health record, intensionally defining a reference set, or restricting the range of an attribute in the SNOMED CT concept model.
This specification defines the format used by SNOMED International's Machine Readable Concept Model (MRCM). The MRCM represents the SNOMED CT concept model in a form that can be read and tested by a computer. The MRCM is distributed as a set of reference sets with the SNOMED CT International Edition.
This document provides a specification of the SNOMED CT Medicinal Product hierarchy's data model in the international edition of SNOMED CT. This document also provides a description of how aspects of the SNOMED medicinal product hierarchy correspond with the suite of standards in ISO, collectively known as the "Identification of Medicinal Products" (IDMP) standards.
This guide provides detailed information about the rules by which SNOMED CT international content is authored. It describes SNOMED CT's scope, hierarchies, authoring principles, style guidance and concept model rules.
