I think the difficulty in recognizing such object relations stems from
trying to do everything with a single positional system.
Proposed solution:
Start with a hierarchical container system at its most abstract. Let
each object have a "position" in its container. The interpretation of
the position is left to the container. The position can be a pair of
coordinates meaningful in the plane defined by the room, or a triplet
of coordinates in the 3-D space defined by the room, or
(angle, distance, speed) relative to the room, which is the planet in
whose gravitational field the object resides.
The position could then simply be a string like "inside", "beside" and
"above" to indicate the position relative to the container, without
imposing the same system on the rest of the mud.
