I'd like to understand how much we would need to modify this to benefit from DDI-CDI. I get the impression at very least that the ObservedVariable instance in 2 would need to be a cdi:RepresentedVariable but that the one in 3 would be a cdi:InstanceVariable,
and I feel that means they should have different IRIs - otherwise the combined graph would end up defeating the point of having InstanceVariable at all.</div>

Aside from that aspect, and assuming the Trait and Scale are modeled appropriately and the properties linking them to my ObservedVariable are subproperties of CDI ones, would there be more I need to do to benefit from DDI-CDI for cross-dataset and cross-domain
variable interoperability?</div>
