Obviously, each country has it's own set of rules for some flavours of ways. Look at them as a basket filled with rights and physical variations.
I have the idea of a 'stylesheet"-like function: define several baskets for international use and fill them with adequate tags for each country, addressed by the way's location (right/left of the country border)
Then you only have to fill a basket once per country and you can use the same basket in every country, or at least in lots of them.
ex: a track in Norway surely means something different than in Niger.
Yet, it is a track in both countries.
The same applies to paths without traffic signs.
I see the need for some additional API functions.
The current solution is, simply said, far too abstract and too complicated. It spoils the fun off mapping.
I don't think 5,000 active mappers are enough to make a world map.
But lots of them seem to think it's okay to scare potential newbies away.
til next,
Thomas
