[OSM-legal-talk] use of OSM data in combination with CC BY-SA data

[Simone Aliprandi]

Dear all,
I would like to share in this mailing list use case related use of OSM
data in combination with CC BY-SA data.
I am a consultant for the Global Earthquake Model Foundation,
non-profit international body (based in Italy) which produces open
data and open source software for earthquake risk assessment (read
more: https://www.globalquakemodel.org/gem/).

I hope that this is the correct "place" to post this kind of request.
If not, please excuse me and please suggest any other "place".

The use case is about the Administrative Boundaries in SVIR project.
GEM produces a QGIS plugin which permits the user to construct a model
of Social Vulnerability and Integrated Risk in a GIS environment.  The
user selects one or more countries or sub-national regions and a
series of socio-economic indicators, the tool then downloads
administrative boundary geometries from the GEM’s OpenQuake platform
along with the associated values for the selected indicators. The
indicator values are distributed under the terms of the CC BY-SA v4
license.
Ideally, GEM would like to be able to use OSM administrative boundary
data for the geometry field and distribute the entire file under the
terms of the CC BY-SA v4.  Is this possible?
As a next-best solution we think it should be possible to work with
two separate files: one “geometry” file containing OSM administrative
boundaries and an ID (perhaps an OSM supplied id, perhaps a new ID
assigned by the software) and another containing the indicator values
and a reference to the geometry.
The geometry file would be distributed under the terms of the ODbL,
while the indicator file would be distributed under the terms of the
CC BY-SA license.   Would this approach be acceptable?  If we were to
distribute both files (and associated metadata, README and license
files) in a single ZIP archive, would this be acceptable?

For a more precise description of the structure of GEM data, please
see this document showing tables and maps:

We read the http://wiki.openstreetmap.org/wiki/License/Use_Cases (case
4) page but it does not completely answer to our doubts.
We also studied the OSM-WikiVoyage case
(http://wiki.openstreetmap.org/wiki/Collaboration_with_Wikivoyage)
which is similar to our case but has some substantial differences.
[NOTE: the WikiSherpa link seems to be broken]

Thanks very much for your attention.
Regards,
