I think the proposal is not ready for use or for voting, but there does not
seem to be much progress.

The basics are clear enough I think.

Though I myself would have made things even simpler (e.g. not bother with
functions like approach or excursion, but simply use alternative and branch
as roles), I am toying with the idea to move forward and start adding the

alternative, approach and excursion for wellknown hiking routes in
Nederland, next time I do a regular consistency check on the lot. No
role=main, It’s up to me to ensure that one main route is present when alle
the special roles are filtered out.

I would not use forward and backward roles as these conflict with how they
are used in cycling routes. I prefer all recreational routes to use the
same (or at least compatible) tagging scheme. Same with all the other
suggested refinements and niceties involving access, direction, starting
points, POI’s and what have you: I see too many complications.

I would use the roles on relation type members, not on way members. This
way the maintenance burden is low. Most hiking routes in Nederland have
been sectioned and alternatives/branches already are separate relations.

This basic role tagging would not conflict with current usage, and it would
not affect current non-role renderings. It would be useful for rendering
alternatives and branches differently e.g. dashed or dotted.

Worst case, nobody follows and I wil lose a few hours of work. Best case,
some renderers might think “hey, that’s neat!” and start using the roles.
Middle case, renderers test it and give useful feedback for a better
proposal. If this proposal would lead to different roles, I could simply
alter the roles in the course of regular route maintenance.
