I fixed some more spelling errors and other mistakes on the wiki page.
Please review them.

Summarizing, OSM is authorized to derive works from the "Carta Tecnica
Comunale" and to distribute them under the ODbL but you can't distribute
the source data. If there's an argument against this, I believe it will be
written in this ML.
Anyway the lack of the source data makes it impossible to verify the
correct tagging. We have to trust your derived OSM file.

The OSM file has a source tag on each feature - please remove them. You'll
tag the changeset with the source tag, not individual features.
You wrongly tagged history=memorial features as historic=monument.
Please look at this recent thread on the talk-it ML about correctly tagging
an "oratorio" (e.g. the youth centre, not the church):

OK but I don't think bell towers are places of worship. Other opinions are
What is missing in your proposal is a good tagging plan (i.e. what tags
will be places on different features). Right now I have to look for
features and see if they are tagged correctly.
An (old) example is the following:

It seems you didn't understand it completely.
For example, look at the following building (a church):
There should be only one building tag on the outline. But you have two
building=* and there isn't one on the building outline.
Tags relevant for the complete building should be only on the building
outline (e.g. amenity=place_of_worship + religion=* + denomination=* +
If you want to specify different height and roof on the various parts, you
must place a building:part tag on each of them.
Thus 2D renderers will ignore building:part tags but they will show the
BTW, no church has got a name tag. Will you add them? When?

You still have to update the wiki page about this.

It is wrong to have two POI's - one as a building and one as a node.
Anyway, I haven't understood how and when you will handle these duplicate
BTW, what is wrong with the name "Teatro Olimpico"? You could tag the
feature with name="Teatro all'Antica" ("all'Antica" and not "All'Antica")
and alt_name=""Teatro Olimpico" (
