[OSM-newbies] Locking tags is it possible?

[john whelan]

In Canada we have CANVEC data available for free and we actually import it
into OSM.  This is roughly the equivalent of Ordnance Survey in the UK quite
different to the normal approach in OSM which is to use GPS traces.  I think
the approach would be to use the scripts that have been developed to import
this data into OSM but just bring it into a blank database.  That way we
could use the various utilities and infrastructure that is available for
OSM.

We also have lots of other things that can get imported.  The city has data
is it prepared to release to OSM or anyone else and as that data gets added
to OSM so we can use the same scripts again to pull it in.  Talking to one
of the city planners tonight one of their major problems is combining data
from different sources.  If I can tap into those the eighty programmers on
the opendata side this should be doable.

To engage the citizens it would be nice to let them add or edit POIs.
However Id like to protect the road network and tags, hence the original
question.

Thanks for the thoughts
