terminology binding
terminology binding
A link between a terminology component and an information model artifact.
Notes
Terminology components include SNOMED CT concepts, expressions, reference sets, and constraints.
Information model artifacts include classes and attributes in reference models for electronic health records and communication specifications.
Terminology bindings enables formal specification of rules for:
consistent use of SNOMED CT in an information model; and
transforming data to a shared model of meaning.
There are two distinct types of terminology binding
A value set binding is a terminology binding that represents the set of permitted values that can be used to populate a coded data item.
A meaning binding is a terminology binding that represents the clinical meaning of a data item or collection of data items.
Terminology binding can also refer to the process of creating and maintaining links between terminology components and information model artifacts.
Examples
A set of coded values that may be applied to a particular attribute in an information model. The set may be expressed extensionally (by enumeration of the codes) or intensionally (by rules such as expression constraints).
The association between a named attribute value in the information model and a specific coded value or expression.
A rule that determines the way that a coded expression is constructed, based on multiple attribute values in the information model.
