5.1.3.2 IfcComplexPropertyTemplate

5.1.3.2.1 Semantic definition

The IfcComplexPropertyTemplate defines the template for all complex properties, either the IfcComplexProperty's, or the IfcPhysicalComplexQuantity's. The individual complex property templates are interpreted according to their Name attribute and and optional UsageName attribute.

5.1.3.2.3 Attributes

#	Attribute	Type	Description
IfcRoot (4)
1	GlobalId	IfcGloballyUniqueId	Assignment of a globally unique identifier within the entire software world.
2	OwnerHistory	OPTIONAL IfcOwnerHistory	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, NOTE Only the last modification is stored - either as addition, deletion or modification. IFC4-CHANGE The attribute has been changed to be OPTIONAL.
3	Name	OPTIONAL IfcLabel	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.
4	Description	OPTIONAL IfcText	Optional description, provided for exchanging informative comments.
IfcPropertyDefinition (2)
	HasContext	SET [0:1] OF IfcRelDeclares FOR RelatedDefinitions	Reference to the relationship IfcRelDeclares and thus to the IfcProject or IfcProjectLibrary.
	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.
IfcPropertyTemplate (2)
	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.

IfcComplexPropertyTemplate (3)
5	UsageName	OPTIONAL IfcLabel	Usage description of the IfcComplexPropertyTemplate.
6	TemplateType	OPTIONAL IfcComplexPropertyTemplateTypeEnum	Property type defining whether the property template defines a property as a IfcComplexProperty or IfcPhysicalComplexQuantity
7	HasPropertyTemplates	OPTIONAL SET [1:?] OF IfcPropertyTemplate	Reference to a set of property templates. It should only be provided, if the PropertyType is set to COMPLEX.

5.1.3.2.4 Formal propositions

Name	Description
NoSelfReference	The IfcComplexPropertyTemplate should not reference itself within the set of HasPropertyTemplates.
`SIZEOF(QUERY(temp <* HasPropertyTemplates \| SELF :=: temp)) = 0`
UniquePropertyNames	Every individual IfcPropertyTemplate within the complex property template shall have a unique Name attribute value.
`IfcUniquePropertyTemplateNames(HasPropertyTemplates)`

5.1.3.2.5 Concept usage

Concept	Usage	Description
IfcRoot (2)
Revision Control	General	Ownership, history, and merge state is captured using IfcOwnerHistory.
Software Identity	General	IfcRoot assigns the globally unique ID. In addition it may provide for a name and a description about the concept.
