ABSTRACT This definition may not be instantiated
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:
- in case of IfcComplexPropertyTemplate
- in case of IfcSimplePropertyTemplate
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.
Assignment of a globally unique identifier within the entire software world.
Assignment of the information about the current ownership of that object, including owning actor, application, local identification and information captured about the recent changes of the object,
Optional name for use by the participating software systems or users. For some subtypes of IfcRoot the insertion of the Name attribute may be required. This would be enforced by a where rule.
Optional description, provided for exchanging informative comments.
|HasContext||SET [0:1] OF IfcRelDeclares FOR RelatedDefinitions|
|HasAssociations||SET [0:?] OF IfcRelAssociates FOR RelatedObjects||
Reference to the relationship IfcRelAssociates and thus to those externally defined concepts, like classifications, documents, or library information, which are associated to the property definition.

|PartOfComplexTemplate||SET [0:?] OF IfcComplexPropertyTemplate FOR HasPropertyTemplates||
Reference to a complex property template. It should only be provided, if the PropertyType of the referenced complex property template is set to COMPLEX.
|PartOfPsetTemplate||SET [0:?] OF IfcPropertySetTemplate FOR HasPropertyTemplates||
Reference to the IfcPropertySetTemplate that defines the scope for the IfcPropertyTemplate. A single IfcPropertyTemplate can be defined within the scope of zero, one or many IfcPropertySetTemplate entities.
Ownership, history, and merge state is captured using IfcOwnerHistory.
IfcRoot assigns the globally unique ID. In addition it may provide for a name and a description about the concept.
