From https://labs.etsi.org/rep/saref/saref-portal/-/issues/40 > Datatype properties s4ener:valueSource, s4ener:valueTendency, s4ener:powerSource, s4ener:messagingType, **s4ehaw:banTopology**, s4ehaw:hasGender, all define a range that is a OneOf anonymous class (a class composed of a set of individuals or literals). > > This forbids extensions to use other possible values as the object of these properties. > > Proposal: avoid such modeling, and instead use a subclass of skos:Concept as the range for these properties. and > 2023-09-06: proposal is to define individuals (possibly a list skos concepts), and use a class as the range (possibly the subclass of skos concept under which the individuals are classified). > > agree: @lefranois @bouter @poveda
