I discover that OSM contains 1575 relations of "type=network" (taginfo). I guess its definition is coming from this wiki proposal: http://wiki.openstreetmap.org/wiki/Relations/Proposed/Network
Quotes: "A network groups together routes that share common characteristics, e.g. a common operator, a common classification scheme (e.g. E-road network: "E 1", ..., "E 999"), ... " "Use cases Person A sees a bus route with number 217 and wonders how many other bus routes exist in that city. Renderer M wants to render all German motorways using white font on blue sign (official layout), and all E-roads with white font on green sign. This can be implemented by adding rules for 20614 (view, XML, Potlatch2, iD, JOSM, history, analyze, manage, gpx) and 20645 (view, XML, Potlatch2, iD, JOSM, history, analyze, manage, gpx). Renderer M wants to render all cycle routes that belong to the "D-Netz". However, there are a lot of other national cycle routes as well. " Plus some attached relations examples very explicite. As raised in the "discussion" page, is that not exactly breaking the "relations are not categories" ([1]) principle ? Can we delete such relations when we meet them ?
