You misunderstood the idea/goal behind the multilinestring proposal. It wasn't created to factorize tags of all members. It was used to record one real life feature made of 2 or more OSM way objects. (like a long river, a boundary between two countries all made of hundreds of ways) A key sentence has been added to avoid using it badly : "Do not use it to group loose ways : Relations/Relations_are_not_Categories (like all path in a forest) Example : if the name is not the same for all those ways, then you'd better not use this relation" What you are looking for is a category thing to group "loose ways" sharing a common property but relation weren't made for that : http://wiki.openstreetmap.org/wiki/Relations/Relations_are_not_Categories -- sly (sylvain letuffe) _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
