I think bare_soil or barren_soil are ok values for bare/barren soil. I am convinced that these areas exist, bare soil without spontaneous vegetation, whatever causes it to remain bare for many years.
Barren sounds to me to imply nothing can grow there.Bare sounds more neutral and factual to me, it just says there is nothing but bare soil to mark the area with.Please correct if I am wrong! My preference would be the direct and factual *=bare_soil The key does not really matter as long as it's not landuse, because it is not a use of the land. landcover=bare_soil sounds right to me. natural=bare_soil might exclude areas which are bare because of human causes. But it fits in with natural=bare_rock, and it is a sort of null-option for vegetation from rain forest through grassy plains to nothing growing there. surface=bare_soil is not bad, but surface is generally used as an additional key for a main feature, not a feature in itself. Since soil is positively what you see, I don't think it's just negatively defined. It's soil, with an important visible characteristic that it is bare. Soil with vegatation has its own tags, but the absence of such a tag does not indicate that it is bare soil. All in all, I think natural=bare_soil is the best option, and that it fills an important gap in the mapping of Earth's surface. Question: How sure can you be from satellite imagery or aerial photography that an area is actually bare soil?
