Actually, if you look at the recent usage of "oneway", based on a recent planet.osm, then it's almost entirely oneway=true, where it refers to the direction of the segment/segments it refers to, rather than mentioning.

It's easy enough to reverse the direction of a segment where it's wrong, using the applet, and there are ways of doing it with JOSM (via external scripts at the moment)

Until a lot of people start actually using these keys in navigational software, it's difficult to tell if a simple scheme like "oneway=true" is sufficient.

That was entirely my point, as oneway = true or yes is not mentioned in Map Features. I use it exactly this way and reversed quite a lot of segments. It might be important for new users to see that written somewhere in the refernce rather than somewhere buried deep in the wiki ;) Perhaps I misunderstood the "node id to node id" as actual value, whereas it was meant as conclusion that results out of entering oneway=true and is never entered as value. In that case it will have to be moved to the comments.
Is oneway="nodeId to nodeId" actually used somewhere, seems rather awkward to edit?

My understanding of current usage is that oneway can have any of the following values: 1, yes, true, on, -1. If it is any of the first four values, then the direction is defined to be from the fromNode to the toNode of a segment, or, for a way, from the fromNode of the first segment to the toNode of the last segment in the way. If oneway=-1 then the direction is defined to be from the toNode to the fromNode of a segment, or, for a way, from the toNode of the last segment to the fromNode of the first segment in the way. 80n 23:03, 22 Jul 2006 (BST)
There is going to be a bit of work to do on this one in the new annotations capability on JOSM. If oneway is simply an on or off event it will get tagged as "true" if the box is ticked, but thats no good if the direction of the way or segment is wrong for the direction of travel so there would still need to be an overide. So for now I'll add a further annotation check box to set the direction reversed from that of the segment or way. Blackadder 01:39, 23 Jul 2006 (BST)
On some of my segments, it can also take the values north, south, northeast, etc. (since I don't normally have direction arrows enabled) Ojw 23:14, 22 Jul 2006 (BST)
This is bad for any software using the tags. Makes things a lot more complicated. Wollschaf 11:53, 31 Jul 2006 (BST)
