I can imagine many examples, where this is not possible. Here is a simple one: Assuming a straight street. way1 and way2 together constitute a route-relation, but way3 does not belong to it. That means the route-relation begins at node1 and ends at node3: node1------way1--node2----way2--node3---way3----node4 All nodes are within a straight line. The user moves node3 within the straight line. The street keeps the same form and length. But afterwards the route begins at another point. How will you handle this secretly? How will you make clear to the user the consequences without showing or knowledge of relations? >Not supporting relations is impossible anyway; the API will not allow >the deletion of a node that is part of a relation. Will this apply to the node3 in the example above as well, because the node itself is not member of the relation. It is only part of a way, which is member of the relation. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
