For publishing Open Data, the CC-licenses have become quite popular, because they allow an easy-to-use modular selection of rights and obligations (BY, SA, NC, ND). However, there are also database licenses that cover the same rights and obligations as the CC-licenses:
- Public Domain Dedication and License (PDDL) ==> corresponds to CC0
- Attribution License (ODC-By) ==> corresponds to CC-BY
- Open Database License (ODC-ODbL) ==> corresponds to CC-BY-SA
Do these have advantages (or disadvantages) over the CC-licenses?
