A value domain is a set of permissible values.

In the context of ISO 11179, a domain is the set of possible data values of an attribute. A “data value” is an element of a value domain. “Enumerated value domain” is a value domain that is specified by a list of all its permissible values.

The value domain provides representation, but has no implication as to what data element concept the values may be associated with or what the values mean.

The permissible values may either be enumerated or expressed via a description.

Non-enumerated value domain is a value domain that is specified by a description rather than a list of all Permissible values.

Non-enumerated value domain description is a description or specification of a rule, reference, or range for a set of all permissible values for the value domain.

Value domain representation class is the class of representation of a value domain.

Attributes of value domain:

Value domain administration record is the administration record for a value domain.

Value domain datatype is the datatype used in a value domain.

Value domain format is a template for the structure of the presentation of the Value(s) e.g. - YYYY-MM-DD for a date.

Value domain maximum character quantity is the maximum number of characters to represent the Data Element value and is applicable only to character datatypes.

Value domain relationship is a relationship among two or more Value domains.

Value domain unit of measure is the unit of measure used in a value domain.
