class Ifc4::IfcPropertyTemplateDefinition : public Ifc4::IfcPropertyDefinition

IfcPropertyTemplateDefinition is a generalization of all property and property set templates. Templates define the collection, types, names, applicable measure types and units of individual properties used in a project. The property template definition can be either:

Property set template - IfcPropertySetTemplate, a collection of property templates that determine the definition of properties used within a project context. Property template - IfcPropertyTemplate, a single template that determines the definition of a particular property used in the same project context. The template may determine the name, description, data type, the unit, or a standard expression for each property that is based on that template.

The subtypes of IfcPropertyTemplateDefinition are declared within a project context. The uppermost template definition (e.g. the IfcPropertySetTemplate including several IfcPropertyTemplate’s) should be related to the context, either IfcProject, or IfcProjectLibrary, using the inherited HasContext inverse attribute.
