Well, basically tags are a kind of protocol, between the tagger and the renderer. Thus, following the process of the IETF would seem to make sense to me: have a chairman who is in charge of evaluating “rough consensus” of the ML users about what tags are Good and what tags are Bad. Also, some mechanical edits lose strictly no information. For the use case described in this thread, here are two mass-retaggings that I can think of: * for all objects with natural=wood, add landcover=trees * for all objects with landuse=forest, add landcover=trees There is no information loss because anyway if the land was tagged properly before, it still will after, and no tag are removed. Then tools can be adapted to generate and render landcover=trees instead of landuse=forest. And finally landuse=forest can be deprecated and replaced by landuse=forestry where it makes sense. The point being, here the important mass-retaggings are only adding tags to already-tagged objects, so there is nothing lost by the change. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
