[OSM-talk] The biggest violation of OpenStreetMap, ever.

Dear all,

We have found the biggest violation in Italy of the OpenStreetMap
license, ever. The author of this violation is the Agenzia delle
Entrate, the Italian revenue service and taxation authority.

We have created a website (in Italian) to show and explain in detail
what they are doing:


OSM’s license, the ODBL[1], provides that in every public use of OSM
data the use of OSM as source has to attributed. This is missing on
the web site of the Agenzia delle Entrate, and we do not appreciate
that the authority whose job is enforcing fiscal legality violates so
blatantly the rights of others, trampling the very few rules bound to
the diffusion of OpenStreetMap: giving credit to the original authors.

Since 2007 the Italian OSM community is liberating data from the
Public Administration, and since then we dream about liberating the
Cadastral data, the data about all the building in Italy, that would
bring a huge wealth to OSM and Italy if they were released with an
open license.

We would have never expected to see OpenStreetMap, a project made by
the people and started 10 years ago, being the foundation of the
system used by the Agenzia delle Entrate to build the website of the
Italian Observatory of the Estate Market (Osservatorio del Mercato
Immobiliare)[0] from the very institution which is administering the
Italian Cadastre.

The agency has copied only some data (buildings and landuse [parks,
rivers, lakes, etc.]) and they superimposed the road graph taken from
another source, probably proprietary data. In fact, the roads are
different from OSM’s ones - in some cases they go right through the
middle of buildings - and they have all of the street names, that in
OSM are, in many cases, missing.

Our goal is to have them admit their wrongdoing and we would like to
start a conversation with them about the release of THEIR data.

On the website you can compare the OpenStreetMap rendering and the one
produced by the Agency; we encourage you to share this news on social
networks using the map when you see a similarity in the two maps.
Everybody should be able to verify this violation himself and send a
personal tweet about it.

One funny thing is that the map we have realized is even better than
the original, since it allows to link a specific place, it is
responsive and it has a better search function with name

Isn’t this a great proof that OpenStreetMap works? The Cadastre, the
keeper of the data about Italian building, is using a database built
by the people to visualize online their territory. The community is
creating applications that work better, the wiki approach is

For the last three months we have tried to contact formally the Agency
(we have sent registered e-mail whose sending date is legally
recognized). We have received no answer. Now, it’s time for us to stop
asking and start demanding.

The following people were involved in this  action: Andrea Borruso,
Cristian Consonni,  Simone Cortesi, Maurizio Napolitano, Stefano

We have dedicated this website to Aaron Swartz (1986-2013).
