Yes it has.

I think it would be nice. I think people involved in Free works should be
willing to help each other out by sharing wherever they can do so without
violating the things which they consider essential to protect.

I see what you are saying, but even here the GPL source requirements may mess
things up art wise. (I need to think about this more and ask around for more
input.) If blind musician bob who has no computer hears a BY-SA song playing
at a friends house, he can make a redivative up in his head, record his
version to tape singing and playing his instrument. He can then dupe the
tapes and sell them. (Following the license.) Now in the case of the GPL, he
has never had the source, he does not have a pc, his derivative never existed
in digital form much less source form. How would the GPL look at cases like
this for non code parts of gpl works? As much as I like the GPL and use it
for my code, I would not want to prevent such uses of my BY-SA works if the
GPL's source language would prevent it.

And I like the source code requirements and would like to see some added to
BY-SA if we can find wording that would require it where it can but not
prevent things like this. I think it was Benjamin and I who were talking
about this late last year either on one of the CC lists or offlist.

I would want my BY-SA works to be able to be used in GPL works but I woulnd
not want to see the problems I bring up above occur. So, it would depend on
whether the GPL source language would cause them or not. I don't know. I have
not thought much at all as to the GPLs working with non-code.

I would not want to disallow that case if delta were code. I would/might if
delta were not code. (I will have to think on this.)

Not only pre-existing GPL work, but someone else's pre-existing work right?
Or
else he can just code up his code before pulling down the BY-SA work. Or if
you mean pre-existing GPL work to be a GPL work that was made date wise
before the BY-SA work was made or something like that, then that will be a
real mess.

I thought I just read that in the draft Mia posted.

From Definitions:

(b) "Creative Commons Compatible License" means a license that is listed at
http://creativecommons.org/compatiblelicenses that: (i) has been approved
by Creative Commons as being essentially equivalent to this License,
including without limitation because that license contains terms that have
the same purpose, meaning and effect as the License Elements of this
License; and, (ii) explicitly permits the relicensing of derivatives of
works
made available under that license under this License.

See (ii)? Now presumably (ii) is redundant in the license itself except as a
safeguard? Surely CC will not list it as approved if it does not do so. Or is
CC going to play games with us and put licenses there as approved but we
can't actually use them because they don't meet (ii)?

Actually Mia, does this need to be fixed?

Thinking further, I think it does need fixing. Here is my suggested rewording:

(b) "Creative Commons Compatible License" means a license that is listed at
http://creativecommons.org/compatiblelicenses that has been approved
by Creative Commons as being essentially equivalent to this License,
including without limitation because that license contains terms that have
the same purpose, meaning and effect as the License Elements of this
License. Note: Creative Commons will not approve such a license unless
it explicitly permits the relicensing of derivatives of works made
available under that license under this License.

> Should THAT be regarded as essential?

This comes down to a power play or a license proliferation play. (Anything
else.)

One way of looking at it is this: If two licenses are willing to allow
two-way
conversion like this, shouldn't they just merge? They could always fork again
later if it became necessary. Or even just one say:

Copyleft License X:

License text: See CC BY-SA license text and substitute Org X for CC and CLX
for BY-SA and add CLX works can be relicenses as CC BY-SA works.

To word it from the other license's side. Of course CC could do that and
point
to Copyleft License X from BY-SA.

I know this is far fetched.

Now, a reason not to do this whole license conversion thing:

As a user uf CC licenses, this convertability forces me to trust CC more than
I do now. Or to try and understand the other licenses as well as I do the CC
ones.

Trust as to intent and as to ability.

Now, is this trust issue real? I am not sure. Since the current license has
the future version and the other jurisdiction wordings, I pretty much have to
have something close to this level of trust right now and I have no way of
reading the licenses in other languages for myself in any case.
