Release File Specification
This specification defines the file formats in which SNOMED CT is provided distributed to SNOMED International Members and Affiliates.
|G||Template Syntax||This specification defines the formal rules for representing slots in SNOMED CT expressions, expression constraints or queries.|
|F||Expression Template Language||This specification defines the formal rules for representing expression templates. The language syntax is derived by combining compositional grammar, template syntax and the expression constraint language.|
This document describes a diagrammatic notation for representing the definition of a concept, an expression, or the relationship between expressions.
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 standard syntax for representing individual clinical meanings using SNOMED CT expressions.
Expression Constraint Language
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.
|H||Machine Readable 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 rules 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.
