The large majority of saref extensions defines one or more subclasses of saref:Property. The saref4bldg en saref4city extension are the sole exceptions that do not provide additional properties. However, the definition of additional properties is inconsistent. The main difference is on how the leaves of the property taxonomy are modelled: as individuals or as classes.
