[OSM-talk] [Osmf-talk] Attribution guideline status update

BTW a potential tweak to the wording (caveat: not discussed with
anybody) that would perhaps make the multiple data sources scenario work
a bit better is to change the current

/If OpenStreetMap data accounts for a minority (less than 50%) part of
the visible map rendering, attribution with other sources on a separate
page that is visible after user interaction is acceptable. /




/If OpenStreetMap is not the largest data provider for the visible map
rendering, attribution with other sources on a separate page that is
visible after user interaction is acceptable./

Which would require on map attribution not only for the 50% and more
case, but also for any case in which the majority of the visible data is
from OSM. It does break down a bit when there are numerous small data
sources of very similar size. Naturally one can argue about what
"largest" means in the context which however applies to the suggested
50% rule too.
