[Tagging] man_made=pipeline - is onewayness implied?

[bulwersator]

How I should tag pipelines with unknown direction?

Hi, I’m the one who introduced this change.  I’m happy to roll it back if needed.


I think I added pipeline to the list of tags that imply onewayness because of discussion here:
http://gis.19327.n5.nabble.com/Underground-Pipelines-td5376988.html


Users can still explicitly tag pipelines as oneway=no if it is known that it is used in both directions.  Being in oneway_tags just means that onewayness is implied and that the feature is rendered with oneway markers.


Thanks, Bryan

According to iD editor man_made=pipeline implies oneway=yes in the direction of way[1]. It is imho a bad idea, because
- it is not mentioned on http://wiki.openstreetmap.org/wiki/Tag:man_made%3Dpipeline
- direction of pipeline may be hard (I mapped some and in every case direction was unknown)
- many pipelines are bidirectional

I plan to 
- file bug for removing pipeline from list of oneway tags in iD
- mention on wiki page for man_made=pipeline that oneway=yes or oneway=-1 may be applied for pipelines moving material in one direction.
