Thanks Ed. I have cleaned up the proposed tagging on the OS
bot<http://wiki.openstreetmap.org/wiki/OS_bot>page to match the
recommended tagging you refer to.

What I don't see is any way to indicate that the information added could
benefit from a ground-survey. NaPTAN imports include the tag
NaPTAN:verified=no. Should we not have something similar for data taken
straight from OS Open data, regardless of whether it is traced or imported
by code? Should we used verified=no, surveyed=no, ground_survey=no or what.
Without any such tag then people wishing to check everything on the ground
are really stuck when people helpfully (or unhelpfully depending on your
viewpoint) add details from OS Opendata.

Can't make much sense of that report - too much noise! Possibly it would be
good to do a cleanup on this tagging at some point.
