IMHO it is a pity that the ODbL is stated explicitly as the license,
because as it is an individual text it might have been possible to obtain
the data in a way completely compatible with the CT, which apparently now
is not the case.
We should strive to obtain general permission for inclusion in
OpenStreetMap under any free and open license, whenever possible.

Martin

Ciao Giorgio,
 I always find your e-mails in the spam folder because the "message has
a from address in yahoo.it but has failed yahoo.it's required tests for

You didn't provide any documentation at that time. It was just a single
mail about a possible import. You then disappeared for about 3 and a half
months.

I do believe it's not a complex import but the review process is performed
to find possible issues and avoid later troubles with bad imported data
(and I already found out some problems with your translated data). There is
no need to rush :-)

The "About & Goals" chapter you use past tenses but most of the actions
still have to happen.

The "Schedule" chapter is missing.

"Import Type" section in "Import Data" chapter is missing. You should
likely say your import is a one-time import, you won't use automated
scripts, all the tags will be entered manually and data will be imported in
the OSM database using JOSM.

You should upload the original dataset.

"Data license" should link to a text copy of the ODbL.

"Type of license" should be "ODbL".

It's fine for me, but please note that you have entered an unwanted space
in the wiki (source= Comune di Sabbioneta - Carta Tecnica Comunale).

As I said, I strongly encourage to use them.

Source data license is not implied. Different data sources can be
distributed under different licenses.

I noticed that logging in is required to download the data. This is not
very friendly towards people without a gmail account. Can you please remove
this limitation?

The data still have some issue:

   - adjacent buildings that are not connected
   - a building has self-intersecting ways
   - churches are tagged with "denominati" (it should be denomination)
   - bell towers are tagged with man_made=campanile (shouldn't it be
   man_made=tower + tower:type=bell_tower?) and without the building tag. See
   https://wiki.openstreetmap.org/wiki/Tag:tower:type%3Dbell_tower
   - some buildings are split in different parts (still tagged as
   building=*) and you assign different heights to them. I'm not an expert
   about this but it seems this is not the right procedure. Please read
   https://wiki.openstreetmap.org/wiki/Key:height#Height_of_buildings and
   https://wiki.openstreetmap.org/wiki/Simple_3D_buildings

Yes you right but I have send my first mail about this import to the talk-it in 
october the 17th. In add you have to consider that this import is not very 
complex in term of number of features and complexity of the process, but off 
course I'll be waiting the ok of the OSM community first.

The original dataset is not an online source, but I add this information in the 
proposal.

Could be good "source=Comune di Sabbioneta - Carta Tecnica Comunale"? About the 
other tags I gonna add all if you think it's the right way to do but I wonder: 
Why remark that the license is ODbl? Isn''t implied?

Actually all the tags I suggested are listed here:
https://wiki.openstreetmap.org/wiki/Proposed_features/changeset_tags

And they have already been used in other imports.

Re: [Talk-it] [Imports] Sabbioneta buildings import

Hi!
   I think you're rushing this import. You sent the email on talk-it just 4
days ago. You should allow more time to reviewers to examine your proposal.

Your proposal miss some of the parts detailed in the
https://wiki.openstreetmap.org/wiki/Import/Plan_Outline. I really suggest
you to use it as a template and fill the different sections.

There is no link to the original data set.

In the licence section, please add the the Municipality of Sabbioneta has
agreed to license the data under the ODbL. Do not suppose non Italian
speakers can read the waiver.

Tagging the changeset with "source=Carta Tecnica Comunale" is not good
enough. It does not link the data to your import. It would be better to tag
it like the following:

   - source=Comune di Sabbioneta
   - source:license=ODbL
   - type=import
   - url=https://wiki.openstreetmap.org/wiki/Sabbioneta

The source tag is mandatory. I strongly encourage to use the other ones too.

The resulting OSM file has a lot of duplicate nodes and nodes of adjacent
buildings not connected. You can check them using JOSM validator.

In multi-polygons, there are some tags that are probably a leftover from
the original dataset: OBJECTID, Entity.

The conflation phase is missing. How do you plan to conflate existing
buildings and imported ones?

The revert plan is missing.

The QA phase is missing.

I guess you are the only one that will perform this import. Please state it
in the "Team Approach" section along with your your current OSM username
(GiorgioL) and import username (GiorgioL-import).

Thanks,

Andrea
