Hi Micaela,

Excuse me for replying so late, I've got quite a bit of catch-up to do
on my mails after the vacations.

As a little note (my main argument is to the following paragraph): A
certain number of years after our death (depending on the country), no
matter the licenses we put to our work, it will become public
domain. There's (fortunately!) nothing we can do about it as
individual authors. And I hope legislators don't allow for it to

You raise an interesting point, which I'll try to generalize: Allowing
for licenses to expire not just on a given time, but on a given
event. That event could be anything clearly verifiable from the
outside (such as the author's death, but not as somebody else
mentioned on the list, the author receiving a given amount of money).

As for the semantics, I favor what I've also seen in this thread,
specifying the condition next to its expiration -
i.e. BY-SA(PUD)-NC(2015) would mean that the work is noncommercial
until year 2015, share-alike while the author is alive, and requires
attribution as long as it's covered by copyright.
