Do you have a link to the Database Directive stuff on osm-talk? I checked
out the list but there's a lot there and wasn't sure which posts to read.
I just got off the phone with the lead counsel of Science Commons, which
is the branch of CC made to deal with data. It was an interesting
conversation, though unfortunately not much good news for CC licenses for
The very quick story is that they don't believe copyright can be applied
to any geospatial data. Thus creative commons licenses don't work, since
they depend on copyright. So people providing data have two options -
public domain or make a contract that completely restricts it.
The longer story is that the Science Commons initiative is about getting
science data more available, which unlike geospatial data is something
that traditionally has been available for all, only published papers about
the data were under copyright. So they would be very hesitant to create a
regime for data licensing that would make it easier for people to put more
restrictions on their data. They are launching a 'facts are free'
campaign soon to get across to the world that one can't copyright
I can see this strategy working decently for science, but unfortunately it
doesn't for geospatial. The legacy we're dealing with is that maps are
power, and something to be kept private for military advantage or economic
gain. We really want a regime that gives a variety of licenses that are
more restrictive than public domain but less so than completely keeping
The lawyer at CC definitely 'got' this, but unfortunately it doesn't line
up with their mission, since most of the topics they're pushing on benefit
from the fact that you can't copyright facts.
He did give some insight in to how one would make such a regime of
licenses if one wanted to. Copyright law doesn't work, since you can't
copyright data. Maps can be copyrighted, but if you can reverse engineer
and extract the data out of them, then that result can not be copyrighted.
So what you would have to do is use contract law. It would be a contract
similar to a non-disclosure agreement - you can't disclose the information
contained in this database unless you follow the set terms. And you could
do copyleft type things in the terms, but it's definitely trickier, and
you somehow have to get people to accept that contract. Which I suppose
isn't insurmountable, since Google Maps and their data providers manage to
get you to accept a contract to not reverse engineer and use tiles off
line and the like.
He was also worried a bit about license incompatibilities, but personally
since they're are practically no open data licenses, that's not so much a
worry for me.
So unfortunately CC isn't going to be much help to us. CC themselves
believe pure data licensed under the CC isn't enforceable in any way,
since it's not copyrightable and so their license doesn't apply. And
Science Commons (who anyone in CC will point you to if you want to do
data, because CC is for creative works) can't really touch it since it
sort of works against their mission.
So if we want to do this right we need to find a lawyer who would
construct a set of contracts for us and guidelines on how to apply them
and get others to accept them. Ideally I think we'd have an 'lgpl' type
option where only modifications to the database need to also be open, and
a 'gpl' one where anything derived has to be similarly open (which would
make it incompatible with things).
Though I suppose we could also just recommend CC, and not tell people that
once they put it out there it's really in the public domain ;) (since CC
wouldn't go to bat for it, it effectively is since it's uncopyrightable
facts that we can easily copy).
