Hello Warin, I find unfair and surprising your last wiki change while the discussion is still ongoing.
1) saying that historic: is one in the category "Repurpose" is amazing. let's take for example the example found of the wiki page of the first key you put in this category historic=archaeological_site historical: civilization=ancient_roman This does not mean that this site is now being reused for something else such as a soccer field. imho the historical namespace: simply means that we are talking about the historical importance of an object. this has nothing to do with the life cycle of an object but rather describes the context in which it was created, like we do with start_date. https://www.openstreetmap.org/way/229279903 If you want to define the current usage of the castle, the tag building:use=residential seems to me more appropriate than claiming that historical: implies a different reuse today. 2) same problem with your classification of namespace was: the tag does not mean that the location has been assigned to something else. For example, if you notice that a restaurant has disappeared, you can modify the object and put was: in front of the key. this does not mean, however, that the place has been reassigned to something else. if so, the fact that it is reassigned will be given by another key, e. g. amenity=bar Therefore, I find that was: is simply a generic namespace that encompasses demolished: and removed: it just says that the previously valid object is no longer valid today, without lingering unnecessarily if the fact that the object has been demolished, removed or any other method depending on the object concerned. demolished:building removed:building and was:building means exactly the same thing to me. this key exist in the past but is out-of-date. I think we would gain visibility by merging these 3 namespace into the generic term was: Regards, Marc _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
