Hello, According to the wiki[0], it seems that the network tag has different meanings and possible values based upon if it is applied to a route relation where route=road vs. route=bicycle/mtb/foot/etc.
If I am understanding this correctly, when route=road, network= the specific network that the road is part of, for example, a US Interstate would be US:I[2] For bicycle/mtb/foot etc. it seems that the network tag indicates the scope of the network, for example a nationwide network cycling network would network=ncn[1] 1) Why can't the network tag have consistent meaning across all route types? For a mapper, as well as a data user, this is confusing. 2) The scope of a cycling/walking/etc. network should be evident from the geographic extent of its members, so isn't network=icn/ncn/etc. redundant? In any event, if the specific network is specified, it will, in most cases, also indicate the general scope.
