[cc-licenses] Time limited CC licenses for version 4.0 ?

when the expiration date hit, the work would morph into CC-BY. It would not  
revert back to All Rights Reserved. I dont think that would even be legally  
possible. All the copies out in the world cease to CC-NC-ND and suddenly  
become ARR? How do you handle the existing copies in the wild? Tell people  
they cant use the work anymore? What if the work started out CC-SA and  
people started collaborating on it and adding to it and modifying it? If it  
reverted to ARR, then that would imply all those derivations would suddenly  
be infringing.

The expiration license could only become more free as time went on, not  
less. Otherwise it doesnt even make sense.

If the work starts out CC-ND-EXP2040, then on January 1, 2040, the work  
becomes CC-BY.

The only caveat I can see is CC-SA-EXP would have to specify that any  
derivative combined with other copyleft licenses would expire at whichever  
license has the later expiration year. The original work can always expire  
at the stated expiration date.  Derivatives would expire at the later date.  
If no expiration exists, it expires when the copyright term legally expires  
and the work enters the public domain.

The idea is to apply it to the condition, not the license. Limiting
the license would fall back to standard copyright = no publicly
licensed re-use.

But yes, it could be offered to all 4 conditions. I don't see a
time-limited BY particularly useful, but a time-limited ND may be
useful, and perhaps a time-limited Share-Alike would be.

My reservation with that is, that I actually believe each of the time
limited licenses should have a real URL, deed, contract, etc. Perhaps
CC drops the distinction between NC-non-SA and NC-SA-licenses (which
is very confusing, since the conditions must be fullfilled, even by
means of other licenses). This would mean, for a time-limited NC
license offered with a maximum term of 25 years, CC would add 15
additional URLs (2012, 2013, 2014, 2015, 2016, 2018, 2020, 2022, 2024,
2026, 2028, 2030, 2032, 2034, 2036).

I would propose for the Version 4 to explore this only for the NC
condition, perhaps as a pilot.
