This is all nice and fine for the short term in those areas where you are filling in a blank map. But over time more and more people will be editing existing objects where this simple approach simply won't work. To give an example: There is this convention centre where the building is drawn from source=whatever_aerial_image. Then they build an extention on the south side. So someone changes *part* of the shape of the building from source=municipal_planning_office. Just putting those two sources semicolon separated in a tag isn't telling you what happened or what is the source of what. _______ Source tags are outdated. One of the main arguments for introducing the changeset tags was that source tags on objects are not "good" enough. -- m.v.g., Cartinus _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
