[OSM-talk] relations

[Jo]

Hi list,

I'm adding relations for bus routes and now I'm going to start using 
them for cycle routes and signed walking paths. I have a few questions 
about them and their implementation in the editors though. I find that 
I'm splitting up roads a lot to indicate that a specific part of it is 
part of a route. Say somebody comes after me and uses Potlatch or JOSM 
to combine these streets again. Would this be possible? Or is it somehow 
prevented? I should probably try it out sometime.

The other way around is that I say that a chunk of a primary road is 
part of my bus route. Then somebody comes by and splits this in two. I 
tried this in josm and all of a sudden only the first part of the 
primary road remained part of the relation. (I think this was before 
committing it to the DB). Ideally when a road that is part of a relation 
is split, both parts should become parts of the relation(s).

And when somebody tries to combine two parts of a road, where one part 
belongs to a relation, this should be prevented. Preferably with a 
message like: 'part of a relation' or something of the kind.
