Prompted by Matt Pocock, I’ve just had a look at the basic foundational ontology. I have to admit to have been left feeling very confused. SpatialRegion have to be either a Zero, One, Two or ThreeDimensionalRegion which seems to preclude other dimensions. They are suggested to be immobile, but I can’t see that this has any meaning. Also, SpatiotemporalRegion is a sibling of TemporalRegion, but not SpatialRegion (they share a common grandparent) and all three are disjoint from each other.

More reading is required, I guess. Unforunately, the documentation seems a bit long. The BFO in a nutshell document is 37 pages in total.
