Hello Habi and Michael,
yesterday I wrote an
email to the Geoinformationszentrum of Lucerne and got already
an answer.
In general they are very pleased, if OSM would use the data but
since this is the first time, they release it in that way, they
have no further experience of how to handle the license issues.
Here is the summary
Habi, can I refer your
experiences and also the Github Link to the contact person in
Lucerne? This might speed up the process.
Cheers,
Gunnar
