Last year we released experimental feature that allows people to create datasets in AcousticBrainz. One problem is that we don’t have a license defined for them. Our data is CC0, but I think it would be nice to give dataset creators an option to ask for a credit.
We’d like to hear some suggestions and opinions on how this can work.
There was already a bit of a discussion on IRC: http://chatlogs.metabrainz.org/brainzbot/metabrainz/2016-05-06/?msg=3584640&page=1.
