All mapping is currently based on physical nodes, but I think that perhaps we
need an abstract element that we can hang things on.

Day by day it becomes more obvious to me that sooner or later
segments/ways distinction will be back with us. Look at this.
A way (street) may belong to many relations, right? Each relation
may contain different part of the street, right? Especially in big
cities where bus routes can be relations and each bus may take
different turns, there will bo no single way/highway comprising more
than one segment (to be precise I think about lines between
crossings which in case of curved street may comprise more
segments). There will obviously MUST be invented 'street' replation
which takes a few segmetns and gives them common name. The other
relation (perish?) could contain all the objects that belong to a
certain place including half of the segments of the streets that
connects two adjacent places.
This shows a little problem which, however, should be automatable, a
new object (node/way|segment) has to be assigned to a different
object (relation) rather then assigning the place relation to the
new object.
I am just shatring my thoughts, maybe someone can come up with some
thing wiser ;-)
