SAREF4BLDG-2. Subclass appears in figures but not in the ontology

Situation: In the figures PhysicalObject is defined as a subclass of geo:SpatialThing. However, this axiom does not appear in the ontology implementation (it appears in the examples).

Proposal: There are two options: either to remove the subclass relation from the figures or to add it to the ontology.

Status: To be discussed.
