I haven't seen this list so cannot comment.
Sorry for that. I had been drawn into a legal discussion on talk and
decided to move it back here, without giving proper context. The context
is this:
Someone asked wether, if we someone has agreed to CT but
we later find out his contribution was "tainted" (their wording), we
would then delete all data contributed by that person. My answer was:
If data is "tainted" in a way that makes in incompatible with the
currently used license then it will have to be removed in order not
to put the project at risk (e.g. data copied from proprietary
sources). This is independent of the license change.
If data is "tainted" in a way that makes it compatible with the
currently used license, but it is likely that the data will have to
be removed should OSM ever change to a different license under the
CT "2/3 of active mappers" clause, then things are difficult - it
would certainly be better in the long run to replace such data by
data that is fully compliant, and I would estimate tools to be
developed that would aim to gradually phase out such limited-release
data and make sure such data is not used to "build upon" if it can be
avoided. But I don't think it would be removed outright - I guess the
decision will be delayed until such time as anyone actually proposes
changing the license again.
There's also a third kind of "tainted" that sits in the middle of
these two, namely data that has e.g. been released CC-BY. Such data
looks compatible at first, but closer inspection (see current
discussion on legal-talk) reveals that CC-BY explicitly forbids
sublicensing, and sublicensing is what the new scheme is all about.
So in that case we'd have a legal outcome (data being distributed
with attribution) but an untidy process that took us there. I don't
know if this is a minor problem that can be ignored, or a
showstopper.
Note that with this "third kind" I was basically trying to echo what you
(FD) had written earlier on legal-talk.
The "list" mentioned in the quote at the top of this email is
http://wiki.openstreetmap.org/wiki/Import/Catalogue.
Someone replied to my message with:
There's also a fourth kind of "tainted" data. Data that might be
compatible with CC-BY-SA, and might be compatible with ODbL, but is
incompatible with the CT's.
To which I again replied
It would be very hard to construct something of that kind. The most
common thing is certainly going to be the above "third" case, where
you have the right to distribute data under CC-BY-SA or maybe even
ODbL or maybe you even have the right to distribute it under any
license with a BY component, but you do not have the right to
authorize a third party (OSMF) to perform such distribution.
For data of your "fourth" kind you would have to have a data provider
who says "you can use my data under CC-BY-SA or ODbL, and you have
the right to sublicense not only under these licenses, but you also
under these licenses plus the additional privilege of further
sublicensing". I'm not aware of such a situation even existing.
If you find anything wrong with that, I'm happy to correct my own
statement on talk.
I shouldn't have started replying to legal stuff on talk in the first
place. Normally i only say "if you want to discuss this come to
legal-talk"...
Bye
Frederik
