    Problem: Personal discussion being shown on public list..
    If you want more than the two of you  to contribute then hold the
    discussion here. :)


I quoted the whole off-list "discussion" with Thorsten. Since it was short and not controversial, I assumed it was in error not using reply all. Apologies if this is against some sort of mailing list etiquette, but in my use of mailing lists it is common people forget to reply all.
Depends on the other person .. some see it as 'private'. Others have just made an error. Personally I try to keep the replay to the list only ... no point in have a separate To: or Cc: thing in the address bar ... and it keeps my mail filters happy :)


    I'd like to, but the problem it causes is that trails in national
    parks and bushland are usually named, and MTB trails have other
    tags including difficulty ratings. By splitting these trails to
    add tiny bridges it makes it harder to maintain consistent tags
    on separate highways, I know of a few trails with half a dozen
    tiny bridges.

    Do you see this as a problem? Or do you think I'm just making a
    storm in a teacup?

    Routes can be had in a relation containing many things including
    bridges.
    The difficulty rating could be placed on separate sections - the
    individual ways, or placed in the relation as the same for all the
    route ... depends on how much detail you want to get.

IMBA difficulty ratings (and those for hiking and horse riding) generally apply to the whole trail even if one section is easier, because you can't just leave the trail if it gets hard and usually trail builders will have decided the classification before starting work. However, trails can sometimes fork (for a decent length) and rejoin, so that does already give you multiple ways.

    If the trail has the same name along all its length .. there is no
    problem in splitting it up and having the same name on the
    separate ways .. just like there in for highways now.
    It is a 'challenge' to maintain some of it .. but it is the truth
    and so that should be what is in OSM.


Great, I wanted to make sure people didn't see bush paths/trails as less important than roads for cars. I guess the only way to avoid fords being mapped incorrectly is to map bridges where they actually exist no matter their size.


It is less complex the way you have it :) ... but less 'truthful'. :(
The broken up roads are a pain when you try to change there classifications .. you have to do it for each bridge and way ... at least that is the present arrangement .. possibly if they were relations it would be easier for the name, classification ...
