I don't think we should be storing any prefix as part of the network=*

network=us_route/state_route/county_route or similar). For example the
"I-x" denotation shouldn't show up anywhere in our tags. If it's an
interstate it should be tagged as such (I suggest network=interstate
but I think there's a precedent on the wiki) and the renderer can add
the "I-" if it wants to.
i agree, it's a rendering prefix for a ref tag value and deserves
its own, separate tag.
For relations I agree, but for ways this doesn’t work. And as renderers
can only handle ways for now…
Sans prefices, the highway=motorway where US Highway 10, Wisconsin
Highway 66, and Interstate Highway 39 run together would have
ref=10;66;39. Not very useful for determining which is which.
i've seen an argument that the correct network value for a county
route involves using the actual county name, e.g.
I wouldn’t say it’s wrong. “Unnecessary” probably, since county roads /
highways / trunk highways don’t, as far as I know, have different signs
within a state.
For the curious, I documented CTH for the county highway ref= prefix
partly because I’m from Wisconsin, but mostly because the
three-character designation is not likely to be mistaken for a state or
country designation. (I know it’s possible to have the renderer look at
where the way is, but it's a hell of a lot simpler to just read the prefix)
