188.8.131.52.1 Semantic definition
The objectified relationship IfcRelDefinesByTemplate defines the relationships between property set template and property sets. Common information about property sets, e.g. the applicable name, description, contained properties, is defined by the property set template and assigned to all property sets.
The IfcRelDefinesByTemplate is a 1-to-N relationship, as it allows for the assignment of one property set template to a single or to many property sets or quantity sets. Those property sets then share the same property set template definition.
