Creative Commons has opened a public comment period for the first draft of CC 4.0 licenses. Guidelines for license development include:
- Producing a 4.0 suite that addresses pressing challenges of important adopters, including those in countries where localized version of CC licenses have not existed, and never may, for any number of reasons;
- Maximizing interoperability, reducing license proliferation and promoting standardization where possible; and
- Longevity and ease of use.
