Hi all, I've noticed that splitter silently removes the "created_by" tag since version 8. I don't see a good reason for that, on the other hand we may also implement a filter to remove more tags. JOSM has a hardcoded list of tags which are silently removed when you edit an object. The JOSM source file OsmPrimitive.java contains this list: "created_by", "converted_by", "geobase:datasetName", "geobase:uuid", "KSJ2:ADS", "KSJ2:ARE", "KSJ2:AdminArea", "KSJ2:COP_label", "KSJ2:DFD", "KSJ2:INT", "KSJ2:INT_label", "KSJ2:LOC", "KSJ2:LPN", "KSJ2:OPC", "KSJ2:PubFacAdmin", "KSJ2:RAC", "KSJ2:RAC_label", "KSJ2:RIC", "KSJ2:RIN", "KSJ2:WSC", "KSJ2:coordinate", "KSJ2:curve_id", "KSJ2:curve_type", "KSJ2:filename", "KSJ2:lake_id", "KSJ2:lat", "KSJ2:long", "KSJ2:river_id", "odbl", "odbl:note", "SK53_bulk:load", "sub_sea:type", "tiger:source", "tiger:separated", "tiger:tlid", "tiger:upload_uuid", "yh:LINE_NAME", "yh:LINE_NUM", "yh:STRUCTURE", "yh:TOTYUMONO", "yh:TYPE", "yh:WIDTH", "yh:WIDTH_RANK" Do you think that splitter should contain such a filter for tags? I think it would be easy to add an option which would read a file with those tags or use a given one. Gerd
