The latest proj datumgrid dataset for Europe now contains some data under the "Data
licence Germany – attribution – version 2.0" [1], but it's not listed in the Good
License list.
It looks somewhat like CC-BY (but in German/English?), though with an additional
mark-your-edits clause.
Is this license acceptable in Fedora?
