Hello,
I would like to know if the new license is compatible with the old one.
will we be able to use CC-SA-2.0 licensed data or we will have to get
new contracts with the donators of data?
for example, we have gotten much of the data for Kosovo donated under
written contract for CC-SA-20, many users helped import this data into
osm.
even if those users agree to relicense, it does not mean that the
original data can be relicensed.
(I am not a lawyer, this is not legal advice.)
The new licence is incompatible with the old. BY-SA 2.0 data cannot be
placed under it without the rightsholder agreeing to relicence.
But the new licence is more compatible with other licences (including
the old) where you want to produce mash ups and other works that
combine data from more than one source.
