it seems some formats does not support topology.

You are right, howewer we lack:
1) hierarchycal ways
2) advanced support for areas
As the first may be a long term goal, the second is necessary to elevate osm
to a full featured model. Actually we cannot define areas with inner holes
while the other formats do.
