<p>Put differently: it makes sense for OSM to be conservative and
when in doubt not to use any material for which we don't have

<div>This is an interesting case. I think we are allowed to
spot errors using closed sources, but we can not use the
source to say what is the right solution. It's as if we are
looking for differences between models, and then using only
the difference data to look further into the matter using
other sources (survey, Bing..). <br>
<br>
</div>
<div>This is interesting to me because I was thinking about
making a service that lists differences between OSM data and
outside closed source data, and then showing only what is
different. Then people would use that "difference data" to
direct their mapping efforts. For example, take closed data
about opening hours, compare to OSM, and only show which OSM
data is wrong according to the closed source. Then mappers
would go survey the shop. Would this be OK?<br>
