There are, as of last Wednesday: 46899 uses with addr:street in this way I described 209340 uses with addr:street used to link a building outline to a street 2947067 uses with addr:street used to link a node to a street Because of the duplication the 46899 way uses actually relate to 83579 equivalent nodes (for comparison) and while this is definitely a far smaller number than the original usage - it is still large in OSM terms. >> also contradicts the definition on wiki. > Somebody must have changed the Wiki.

I would argue that you have just removed the documentation for how people are using the tag. >> Putting the tags on the way prevents inconsistency and duplication. > Duplication is good. It helps with finding errors. No, duplication is almost always bad (caching may be an exception). Inconsistent data is the enemy of all good database management because you can't tell what it means and if data changes it is easy to miss changing it in multiple places. But this may be a religious war there is no point in having, although I am, of course, right :) >> I mean use a polygon / relation to create a polygon for the place (in >> this case Osijek).

The consensus use of the boundary=administrative relation seems to me to be clearly and (unusually!) consistent. http://wiki.openstreetmap.org/wiki/Key:boundary The meaning of a place polygon is also clearly described: http://wiki.openstreetmap.org/wiki/Key:place -- Brian _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
