Ok, so give me some examples of what could happen if NWN in Australia doesn't mean the same as NWN in Germany or Sweden or Japan? Also, while I'm in favour of standards - is there even a standard here? Google "standard rwn nwn lwn iwn", and there is a single relevant hit: http://wiki.openstreetmap.org/wiki/Walking_Routes Second paragraph: ---- Is it worth adopting the same idea as for cycling, i.e. three levels of hierarchy - national, regional, and local. ---- I don't see a standard here. It's *possible* there is a European standard. Even if that were the case, Australia is not in Europe, so the merits of following that standard are debatable, given our vastly different scale, geography, population etc. The only place I can even see a non-tautological definition for these networks is here: http://wiki.openstreetmap.org/wiki/Relation:route ---- foot iwn International walking network: long distance paths used for walking routes that cross several countries, for example the Camino de Santiago foot nwn National walking network: long distance paths used for walking routes that cross countries foot rwn Regional walking network: used for walking routes that cross regions. In Belgium and the Netherlands this is used for the walking node networks foot lwn Local walking network: used for small local walking routes. Could be touristic loops or routes crossing a city ---- Clearly this scheme was devised only with Europe in mind. A "long distance path" that "crosses a country" in Australia would be as long as an IWN in Europe. A regional trail in Australia would be as long as a NWN in Europe.

You're effectively arguing that this map should never show those trails at this scale. Therefore, if Australians want to see maps like that at this scale, they're going to need an Australian-specific map that interprets NWN/RWN/LWN differently. How does this support interoperability? NWN (Switzerland): A trail of approximately 200-500km NWN (Australia): A trail of approximately 500-10000km. ... Rather different things, imho.
