Creative Commons, which promotes access to open resources, has requested comments and contributions for their latest draft proposals. Their main goals are:

• 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.

Initiall feedback is due to be made public in June.
