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

| # | Attribute | Type | Cardinality | Description | C |
|---|---|---|---|---|---|
| IfcRoot | |||||
| 1 | GlobalId | IfcGloballyUniqueId | [1:1] | Assignment of a globally unique identifier within the entire software world. | X |
| 2 | OwnerHistory | IfcOwnerHistory | [0:1] |
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 in stored - either as addition, deletion or modification. | X |
| 3 | Name | IfcLabel | [0:1] | 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. | X |
| 4 | Description | IfcText | [0:1] | Optional description, provided for exchanging informative comments. | X |
| IfcPropertyDefinition | |||||
| HasContext | IfcRelDeclares @RelatedDefinitions | S[0:1] | X | ||
| HasAssociations | IfcRelAssociates @RelatedObjects | S[0:?] | 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. | X | |
| IfcPropertySetDefinition | |||||
| DefinesType | IfcTypeObject @HasPropertySets | S[0:?] | The type object to which the property set is assigned. The property set acts as a shared property set to all occurrences of the type object.
NOTE The relationship between the IfcPropertySetDefinition and the IfcTypeObject is a direct relationship, not utilizing IfcRelDefinesByProperties, for maintaining compatibility with earlier releases of this standard. | X | |
| IsDefinedBy | IfcRelDefinesByTemplate @RelatedPropertySets | S[0:?] | Relation to the property set template, via the objectified relationship IfcRelDefinesByTemplate, that, if given, provides the definition template for the property set or quantity set and its properties. | X | |
| DefinesOccurrence | IfcRelDefinesByProperties @RelatingPropertyDefinition | S[0:?] | Reference to the relation to one or many object occurrences that are characterized by the property set definition. A single property set can be assigned to multiple object occurrences using the objectified relationship IfcRefDefinesByProperties. | X | |
