Semantic definitions at the entity

Entity definition

The objectified relationship (IfcRelAssociatesDataset) handles the assignment of a dataset (items of the select IfcDatasetSelect) to objects occurrences (subtypes of IfcObject) or object types (subtypes of IfcTypeObject).

The relationship is used to assign a dataset reference or a more detailed dataset information to objects. A single dataset reference can be applied to multiple objects.

The inherited attribute RelatedObjects define the objects to which the document association is applied. The attribute RelatingDataset is the reference to a dataset reference, applied to the object(s).
