So to get back to the basics of this thread... I think we can all

So then the question is what tags to use on relations.
All documented long ago at
http://wiki.openstreetmap.org/wiki/Relation:route (especially
http://wiki.openstreetmap.org/wiki/Relation:route#Tags )
There does seem to be some debate about county roads. I would probably
throw my vote in with something like "network=US:KS:Riley"
Yup, there’s debate about that.
I’d prefer something like US:KS:CTH or US:KS:COUNTY. Or even US:KS:CR,
though I don’t like the two-character code as it looks just like a state
abbreviation.
IMO, connecting the road to the county should be done with a relation
(super-relation actually) between the route and the boundary of the
applicable county.
I do have one question: Is it acceptable/proper to have a name=* tag
on a relation? I have seen it on some and have actually used it a
couple of times - for example "name=KS 18"
It is incorrect on a route relation unless it does have a name, like
“The Joe Q. Bloggs Memorial Parkway” or something like that.
The only advantage I see is that it makes things easier to read in
editors and when browsing data since the name tag is used when
displaying relations in lists or listing what relations a way is part
of instead of just showing the numeric ID. But this is a case of
tagging for tools so I could see reasonable objections to it.
Exactly. The tools should be improved. The interface for relations in
josm (not sure about potlatch) is atrocious.
Let's focus on getting a concrete system in place that we
can go beat the rendering people over the head with. I think if we as
a US community come out with a solid plan and say "we need this now"
people will listen.
We’ve had one for a long time. What’s needed is for someone to do the
hard (“trivial” as Anthony would say) work of actually making use of the
plan.
