SNOMED CT Full MRCM Attribute Range Reference Set

An MRCM (Machine Readable Concept Model) Attribute Range Reference Set allows attributes to be associated with a valid value range for a given SNOMED CT content type and rule strength. The range of each attribute is defined using an Expression Constraint. This expression constraint represents the set of concepts, expressions, or concrete values that may be used as the value of the given attribute.一种可机器读取的概念模型属性范围参照集允许将属性与特定SNOMED CT内容类型及规则强度下的有效值域关联。每个属性的值域均通过表达式约束来定义。该表达式约束表征了一组可能用作给定属性值的术语、表达式或具体数值。
