topic history before the element existed
An OSM element does not necessarily refer to a real world object. Considering https://gitlab.gistools.geog.uni-heidelberg.de/giscience/deleted_map where elements seem to get deleted to be corrected (a very similar object gets drawn after a deletion), we should consider the history before the element was drawn.
- only objects with the same tag
- all objects of same category (see diversity)
What do we consider, the area covered?
