This is certainly true. We’ve been discussing this (mostly internally with @klaus.aengenvoort and some other people) since a few years; - as far as I remember we talked about this with @TLiebich in February 2014, also regarding this related topic: [How is a IfcPropertySet related to its IfcPropertySetTemplate? - #2 by stegh](https://forums.buildingsmart.org/t/how-is-a-ifcpropertyset-related-to-its-ifcpropertysettemplate/243/2) From my point of view: GUIDs would certainly help. @jonm also supports this… 😉 [How is a IfcPropertySet related to its IfcPropertySetTemplate? - #4 by stegh](https://forums.buildingsmart.org/t/how-is-a-ifcpropertyset-related-to-its-ifcpropertysettemplate/243/4) > [@How is a IfcPropertySet related to its IfcPropertySetTemplate?](https://forums.buildingsmart.org/t/how-is-a-ifcpropertyset-related-to-its-ifcpropertysettemplate/243/3): > > Klaus seems to be proposing that we add an optional attribute (reference Id) to an ifc property (which could/should be a guid) that would allow identification of the property. I would certainly support this. --- _[View the full topic](https://forums.buildingsmart.org/t/bsdd-guids-at-the-field-property-level/362)._
