[Tagging] [OSM-talk] Crossroad names

[Vladimir Vyskocil]

I think it's time to switch to the tagging list !

The tagging scheme that seems preferred in this discussion is the following :

- simple named junctions : use junction=yes and name=*
- complex named junctions with several lanes crossing a different points :
	two propositions : 
		- use a relation { type=junction, name=*,  junction role,...} referencing all the crossing points between the lanes
		- use a place { tag=junction or crossroads, name=* } on a area englobing the crossing points

All right ? What are your opinions on this ?
