Check Open Data Commons for licensing data, in particular check Open Database License. You might also want to check how and why OpenStreeMap moved from CC to ODBL.
Frage
The GNU General Public License (GPL) is for software, and the GNU Free Document License (FDL) is for documentation---is there a GNU-like license for data? Specifically, I would like a license that allows the same kinds of permissions that GPL software has (eg, redistribution, access) but for data.
