there are some very few occurences of previously mentioned "flow_direction" http://taginfo.osm.org/keys/flow_direction#overview we could also use incline=up/down (is in use, but rarely in conjunction with waterways) More often I found the undocumented "oneway:flow" http://taginfo.osm.org/keys/oneway%3Aflow (there is a oneway restriction in flow direction?) values are yes/no. There are also 634 times "FlowDir" (atypical key name, likely from an import) Personally from the values in use that I found I'd go with "flow_direction" (values in use are "forward" and "both"), because its not an abbreviation and quite verbose in what it is describing. "oneway:flow" doesn't make much sense to me. cheers, Martin
