So if you want to replace one variant with the other, you end up doing it constantly, as users seem to constantly add more collapsed buildings in both variants. Also it looks like the 'easier' variant is more accepted. Yes, it is 'ugly' in terms of data quality, but I see no problem so far. Maybe eventually it gets reasonable to unify those tagging variants, when the growing rate sinks significantly, but, in the long term the information will be removed from OSM anyway. We can learn from this and do it better the next time. Regards Micha ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Looks like most other groups use our road data and do the damage assessment on buildings themselves. So it's probably not really important.

Why do you want to replace a simple, understandable, well established, broadly supported tag with something THAT complicated? It's ok, that another tag with the same meaning exists due to imports, but please DO NOT change well known and used tags with another one coming from an import.

Corrected two occurences.

Where a "building=collapsed" was present, I want to set "earthquake:damage=collapsed_building" instead. This would touch about 815 objects. Everywhere "earthquake:damage=collapsed_building" was present, I want to add "building=yes" which seems logical and helps proper rendering. This would touch 2290 objects. All that seems logical to me, and I embarked upon doing it. I managed to make clean selections and edit them - but then on uploading my changeset would conflict with other data. I tried to get http://labs.geofabrik.de/haiti/latest.osm.bz2 and then as fast as I could (that is - not so fast on my four years old laptop) to replace "building=collapsed" with "earthquake:damage=collapsed_building" and then add "building=yes" everywhere "earthquake:damage=collapsed_building" was set... And everytime a conflict would prevent upload. I tried again five times... I give up for now - I'm going to bed - feel free to take it from there. Am I doing something wrong ? Is JOSM the right tool for editing tags on 3k objects or is there another way I sould use ? ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

The text from the wiki at the above adresse : --- After checking the data, please remove the fixme tags in front of the other tags. Please keep the source tags. To find data that needs fixing (data with FIXME= ), open the ithaca-import-fixme.gpx from here in JOSM and zoom to the little crosses. --- So yes, there is definitely a reason for "fixme" that I was not aware of.

Now we have : tag value uses earthquake:damage collapsed_building 1,499 fixme:building collapsed 1,492 buildingcollapsed 787 earthquake_damage collapsed 2 Time for harmonization ? "earthquake_damage" should obviously be "earthquake:damage". "fixme:building=collapsed" looks like it should be "earthquake:damage=collapsed_building" - but maybe there is a reason for "fixme" that I'm not aware of. "earthquake:damage=collapsed_building" is the ITHACA way. Should we convert all the "building=collapsed" to it ? I would say yes, because "collapsed" is not a type of building but a building attribute - the ITHACA way is semantically superior. If no one is depending on "fixme:building=collapsed" or "building=collapsed" then I'll convert them. Does the map rendering of collapsed buildings such as http://zvenzzon.mine.nu:81/map.html understand "earthquake:damage=collapsed_building" ?
