## 5.1.3.8.1 Semantic definition

IfcPreDefinedPropertySet is a generalization of all statically defined property sets that are assigned to an object or type object. The statically or pre-defined property sets are entities with a fixed list of attributes having particular defined data types.

Property sets are related to other objects by using the relationship object that refers to the corresponding object:

• Occurrence Object: IfcRelDefinesByProperties using the inverse attribute DefinesOccurrence.
• Type Object: using a direct link by inverse attribute DefinesType.

IfcPreDefinedPropertySet's can be assigned to objects and object types but do not have a defining property set template.
