I would like to get your oppinion regarding the ODbL for the use case
described below. I have asked several attendants at SOT-M in Vienna and
was encouraged to put my question on this email list.
The background is as follows: For marketing purposes, like finding a
site for a new facility, companies can buy statistical data that is
related to road objects of either Navteq or Teleatlas. The data can be
presented on a map with different colours or other styles for the roads.
The question is, whether the ODbL allows such companies to use OSM
rather than Navteq or Teleatlas, if they transfer the statistical data
via a matching table to the OSM road objects.
Here is the use case " Transfer of data from other road networks":
One can license data associated with proprietary road networks. An
example would be a table (T0) with Navteq identifiers as keys, numbers
of households, dominant type of buildings, buying power, traffic
frequencies. Given another table that maps Navteq identifiers to
matching OSM identifiers one could translate the licensed data to OSM.
On a thematic OSM map one could use different styles (colour, breadth,
…) for the roads in order to visualize the transferred data.
T0 may look like this:
Navteq-ID | Number of households | Buying power | ...
There are two ways to generate the map. Either create a data table (T1)
with OSM road identifiers and the transferred data. Or create a mapping
table (T2) with OSM road identifiers and the matching Navteq
identifiers. For the OSM road objects to be displayed in the map,
dynamically merge data from (T2) and (T0) for the objects currently on
T1 may look like this:
OSM-ID | Associated Navteq-ID | Number of households | Buying power | ...
T2 may look like this:
OSM-ID | Associated Navteq-ID
According to the ODbL, the OSM map - or an application with this map -
would be a produced work. Either the OSM data table (T1) or the mapping
table (T2) would be a derivative database and would have to be provided
under ODbL. In either case, the licensed data table (T0) would not fall
under the ODbL, either because it is not used for the map or because it
is an independent part in a collective database, which it forms together
Thank you very much in advance for your comments. They are important
because at Fraunhofer, we would like to use OSM data in applied research
