How come osm.org doesn't have to display a map ©OpenStreetMap contributors, licensed CC-by-SA? Even Google maps does that for map data (their Copyright/bug report line is pretty sweet btw). Actually it doesn't say "©OSM" anywhere on the main page. |

No user of OpenStreetMap data has to display the attribution right on top of the map, that just happens to be the most popular style of attribution. The CC-by-sa demands attribution "in any reasonable manner", and requires that "at a minimum such credit will appear where any other comparable authorship credit appears". A link with an obvious text (such as the "Copyright & License" link on osm.org) satisfies these requirements. |
