Logical Model: CR - Detailed Descriptions

Active as of 2024-10-25

Definitions for the CR logical model.

Guidance on how to interpret the contents of this table can be found here

0. CR
Definition

A concept qualifier code with optionally named role. Both qualifier role and value codes must be defined by the coding system. For example, if SNOMED RT defines a concept "leg", a role relation "has-laterality", and another concept "left", the concept role relation allows to add the qualifier "has-laterality: left" to a primary code "leg" to construct the meaning "left leg".

2. CR.inverted
Definition

Indicates if the sense of the role name is inverted. This can be used in cases where the underlying code system defines inversion but does not provide reciprocal pairs of role names. By default, inverted is false.

4. CR.name
Definition

Specifies the manner in which the concept role value contributes to the meaning of a code phrase. For example, if SNOMED RT defines a concept "leg", a role relation "has-laterality", and another concept "left", the concept role relation allows to add the qualifier "has-laterality: left" to a primary code "leg" to construct the meaning "left leg". In this example "has-laterality" is the CR.name.

6. CR.value
Definition

The concept that modifies the primary code of a code phrase through the role relation. For example, if SNOMED RT defines a concept "leg", a role relation "has-laterality", and another concept "left", the concept role relation allows adding the qualifier "has-laterality: left" to a primary code "leg" to construct the meaning "left leg". In this example "left" is the CR.value.
