reciprocal data agreements

[Richard Weait]

Dear legal-talk,

I wonder if either cc-by-sa, or ODbL anticipate a reciprocal data
agreement between OSM and another project with a different license?

Imagine a data provider using perhaps cc-by, or a BSD style permissive
license contributes their data to OSM.
Imagine then that they would like to monitor changes in OSM to data
that originated from their source.
Imagine then that they would like to incorporate those changes, with
or without further vetting, back into their dataset under their
license.

My understanding is this return of the data to the source would not be
permitted, as is, with either license.

I suggest that we do want to permit this sort of a reciprocal data agreement.

Am I incorrect in my understanding of the licenses and would this be
permitted already?
Could a community guideline address this and permit it in the ODbL
when and if adopted?

Thoughts?

Best regards,
Richard

I agree that this would be very desirable; however it would allow our
sacred data to leave the protecting cage of ODbL and live on under a
CC-BY-SA or, God forbid, a BSD license which would be unpalatable to
many contributors.

Bye
Frederik

Indeed.  We use a viral license, in part, because we want folks to
contribute their data to OSM.  We all benefit from the additional data
donated to OSM.  The donor has done exactly as we asked, and donated
to OSM under the OSM license for the greater good.

What more can a data contributor do?  They contribute their best data;
we all do.  Perhaps we improve it further.  Perhaps we update it
faster.  Perhaps they do.  Do we want to encourage the free exchange
of data-improvements between the original donor and OSM?

Do we eat our own dog food, or do we eat our young?  ;-)

if they've got balls of steel, they could just claim that CC BY-SA
doesn't apply to factual data and just take the current OSM data ;-)

on a more serious note, this is very much like the Biba model. if we
order licenses by property: BY-SA, BY, 0, then it follows a
write-down, read-up model. in other words, even if we had a BSD type
license, our data could be incorporated into BY-SA projects, but not
into PD projects. the only way to become a universal donor also means
rejecting non-PD imports.

personally, i think that imports are bad, m'kay? so i'm not that bothered ;-)

cheers,

matt
