One information will be lost for sure with the current model which is NOT comparabel to Wikipedia. Time! If you ever wish to show map items before this moment we need old information. For plants is's obvious that you will gather data from the comparison of different times. I am not going conform with you just to concentrate on the thin layer of presence. regards, Stephan. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
