The changeset comment would work, rather than ID -- the changesets
need to be very small these days, so it takes thousands of IDs for an
import.

Why not just use the changeset ID... that's what its there for after all.

will the initial import be done automatically? if so, it may be useful
to let a new ad-hoc user do it, and later assume that whatever has
that user as the last author hasn't been changed

this would also help with copyright issues

What happens if the Regional Administration of Lombardy would some day offer  a
major update to the data to be imported now?  Can the imported features be
identified later so that they could be updated or deleted+inserted again? 
Update should naturally happen automatically only if no OSM user has touched the
feature after initial import.

I think that guidelines for updating imported data comes more and more
important.  We have already imports from AND, Tiger, Canadian, German and
African sources, French cadastre, Estonian city data, Italian data, MassGIS etc.
OSM is not at all just user contributed data.  Perhaps it could be better
described as a collection of user contributed imported data enhanced by users.

Great deal of the imported data is maintained by the original data providers. It
would be a waste of OSM resources not to take the updates as well.

I think you are right, adding information to the changeset will be enough.

Unless there is a very good reason to tag every single object, consider 
whether it might be sufficient to have that kind of information in the 
changeset. Changesets can have any number of tags, so you could, for 
example, write the WMS URL and other metadata into the changeset. Let's 
try and move metadata away from the individual objects and into the 
changeset.

Information about the real world goes directly into OSM tags: What is 
this, how high is it, what colour does it have, when was it built, etc.

Information about that information goes into the changeset: Why do we 
known, how did we measure, who gave us permission, and what music did we 
hear during out editing session.

Bye
Frederik

[OSM-talk] authorization to import Lombardy data in OSM

[Simone Cortesi]

Hi,

I've just received authorization to import all or the Regional
Administration of Lombardy data in OpenStreetMap. Lombardy, the place
where I live, now joins three other italian regions which explicitly
gave authorization to OSMappers to import data in to the DB.

We can either use WMS or download shapefiles, then to be automatically
imported in the main DB.

It would be very useful IMHO to have such a nice Plugin like the one
for the French Cadastre
, so it
would be easy to add source key/value as asked by the Regional
Government. Anyone up to the task of making a general purpose "source
adder" JOSM plugin?

Thanks,
Simone.
