So far only 3 people left their vote. At the moment ‘front’ is the leader with a +3 score, without ‘against’ votes.
To conclude the discussion I propose to change the definition as follows:
Assume the “viewer” stands straight in front of the sign, looking at it.
position:left / :right Distance towards the left-/right-hand-side of the viewer
position:front Distance away from the sign towards the viewer. Might be negative if the sign points to a place behind it
position:heading Heading from the sign towards the object, given as cardinal direction
position:distance Straight line distance between sign and object
orientation Cardinal direction of the sign face itself (e.g. 90 if it gets full morning sun facing East)
Usually either
- left/right and front
- heading and distance
should be present on any object, depending on the information available.
To clean up the current tagging I guess it is save to change all existing position:distance to position:front, if they are tagged together with position:left or :right.
