Obviously I can's peak for Yahoo (I think I should spell that "Yahoo!") but NearMap does care; we worked hard to make sure that our PhotoMaps could be used as the basis for OpenStreetMap, we want to support OSM and seeing "nearmap" as the source is a direct reflection of that :) Plus our images are usable under CC-BY-SA, so the BY part is addressed by setting the source.
Personally, I'd welcome some more clarity on the use of the source tag when editing existing features. We're working on providing easy edit access from our site to correct or add names to streets, and to add address-related information. Where a street name is added or corrected via our site, our current approach is to add or modify the source tag to be "nearmap", but yesterday I was (coincidentally) looking at whether we should be appending to any existing source so that we don't inadvertently remove attribution. The wiki page <http://wiki.openstreetmap.org/wiki/Key:source> is, at best, unclear on this subject. ...and John Smith <deltafoxtrot...@gmail.com> also commented: > As for Nearmap, that is a curious situation in and of itself, on one > hand you can only release data under a share alike license, primarily >so they can have access to the data if they want, but they don't > require attribution. Hmm... not quite. The licence linked to from our Community Licence page<http://www.nearmap.com/products/community-licence> is CC-BY-SA 3.0 <http://creativecommons.org/licenses/by-sa/3.0/>, which does require attribution; one has to attribute our PhotoMaps to use when they're used under that licence. Our Community Licence page specifically addresses using our PhotoMaps to derive data for OSM, making it clear that the deriver owns the derived works, but must use CC-BY-SA to distribute them. Use of the source tag to mark our data as the basis of the derived data is enough attribution to comply; Potlatch does that automatically. And of course the OSM wiki page about using our data<http://wiki.openstreetmap.org/wiki/Nearmap#Attribution>also mentions the tag. Cheers b -- Ben Last Development Manager (HyperWeb) NearMap Pty Ltd
