Thanks Ilya for your comment,
And also thanks to Martin.
"Viral aspects" like Martin puts it, sound a bit like a disease :-)
However, If I understand Ilya correctly, the Odbl only applies to data that
is made publicly available.
That, in turn, means, any data put together using also OSM data, that is not
publicly accessible, but only in internal networks, can be produced?
Is that interpretation correct?
