The objectified relationship (IfcRelAssociatesLibrary) handles the assignment of a library item (items of the select IfcLibrarySelect) to subtypes of IfcObjectDefinition or IfcPropertyDefinition.
The relationship is used to assign a library reference or a more detailed link to a library information to objects, property sets or types. A single library reference can be applied to multiple items.
The inherited attribute RelatedObjects define the items to which the library association is applied. The attribute RelatingLibrary is the reference to a library reference, applied to the item(s).
