Entity definition

The IfcPropertyTemplate is an abstract supertype comprising the templates for all dynamically extensible properties, either as an IfcComplexPropertyTemplate, or an IfcSimplePropertyTemplate. These templates determine the structure of:

The individual property templates are interpreted according to their Name attribute and may have a predefined property type, property unit, and property data type. A template however shall not have measure values, or quantity values assigned.

NOTE  Property templates can form part of a property library used and attached as part of a project library. In general the IfcPropertySetTemplate, containing the subtypes of IfcPropertyTemplate would be directly linked to the IfcProjectLibrary.

HISTORY  New entity in IFC4.
