As you can read it, my goal is simple: stop people tagging for the renderer by making their tagging visible on OSM.org standard map despite a -- hopefully temporary -- lack of rendering definition. You people focused on the choice of multicolor by the mappers to shoot this suggestion down while there is no multicolor and not even a choice needed at all: a single color chosen by the renderers suffices. Hence, the applauded smarties box mockery is ridiculous as smarties of the same color every 50 cm make a funny present box and tagging for the renderer makes a better looking one regarding color anyway. On the other hand, to address another critique, RENDER can indicate that it means that the feature is considered important either only for the standard map or for some other categories of maps.
Pragmatically, open OSM.org and search for "mini golf" <http://www.openstreetmap.org/search?query=mini%20golf>. Clicking on a result will show you the feature highlighted single color. RENDER would render it much the same way on the normal map, but dim. Now if the tourist returns to the normal maps, and he can or he cannot see what he has just found, depending on its tagging for the renderer or not. Look, dear, they say that showing our mini golfs would "break the model of decoupling the factual mapping database from the data consumers and their choices". Let us try Google or Michelin maps instead, they may copy OSM data and show it. On one hand I advocate happy mappers tagging features that RENDER can show and happy renderers that can make statistics of RENDER usage to see what rendering definitions are the most needed. As soon as a new rendering definition is made, all the features auto-magically use it. Should abuse of RENDER be found, an invisible rendering can be defined for the feature. On the other hand, you advocate unhappy mappers tagging useful features for the renderer in order to not tag in vain. The process is much out of control and, should a rendering definition appear for some or those features, the tagging already done will remain in the "for renderer", smarties like state. You might have a better idea or improve mine instead of disparaging it. Up to you. This will probably be my last message. André.
