Dear Dominic, Yes this is as it should be. This class is the super set of the human made object and human made feature. As such its instances include both of its child classes’ instances. It represents what they share in common which is essentially being a physical kind of thing and being the kind of thing made by humans. It is also stated by the ontology that this then is from where you can begin to speak of representations. According to crm representations are only made by humans.
So if you need to talk about things that are movable you hop down to e22 and if you are needing to make statements about things that are features hop down to e25. E24 is a class that likely isn’t invoked much directly but rather serves to support the representation of some things that are common in its child classes. Linked.art takes the decision to not split the hairs about whether a thing can be moved or not (since ultimately anything likely could be moved with a little imagination) and uses e22. But for some e25 serves useful purposes for indicating the physical objects that inhere in other objects. Is that helpful or addressing the direction of your question or did you have something else in mind?
