For me, as a PD advocate, the more licenses you license the stuff under 
the better as it will combine the loopholes of every single one.

If, however, you intend to protect our data by putting it under a 
share-alike data, then any additional license you add weakens that 
protection.

It's curious that two of the strongest defences of 'strong share-alike' come 
from
yourself and Richard F. - but both of you prefer public domain.  I, too, would
prefer public domain over the ODbL.  What's going on?  Shouldn't we stop adding
more legalese and just focus on transitioning OSM to PD or attribution-only?

There's at least one major data contribution that came about because of

Reverse engineer is a euphemism for recreate. ;-)

Since the data isn't covered by BY-SA, if I recreate the data it isn't 
covered by BY-SA.


(See Jordan's secret sauce explanation on odc-discuss.)


So it should be entirely possible to reproduce most of planet.osm or
at least the useful part of it (so e.g. not the object IDs and not
their order) which would not be covered by database rights or
copyright of OSMF.  For example I could produce z30 tiles with a
public domain mapnik stylesheet and my friend could run a program to
produce a .osm file taking the tileset and the stylesheet as input.


Steganography doesn't defeat copyright.


If you use a CC licenced work to recreate another, non-CC-licenced

work, for example if you rearrange it to make the score and lyrics to a
Lady Gaga song then record that, the work that you have reverse
engineered still breaks copyright despite the fact that you have used a
CC licenced work to make it.


Is there any known case that would show that this is how copyright
works?  I'm no lawyer, but copyright is mostly reasonable to me
whereas what you explain would make it unreasonable.


http://www.poster.net/star-wars/star-wars-episode-ii-yoda-photomosaic-4900333.jpg

The above image could be made of BY or BY-SA images and the resulting 
image would still infringe on the copyright in the movie and the 
character it depicts.



For example say I'm using the CC-BY-SA photographs from flickr to
create a great photo wall, placing the pictures in alphabetical order.
  How do I know that I'm not recreating a differently licensed work by
somebody else, from which all the pictures were cut out?


You don't. But if you're using them to create an image of Yoda, it 
doesn't matter what images you use.

Well, depends on what you mean by that.  MapQuest certainly can
(physically) make a map tile from OSM data and put a notice on the
bottom of the screen saying this map tile is released under
CC-BY-SA.

Right, and I could photocopy today's Financial Times and put the same notice
on it, but that's not what I mean by 'can' or 'cannot'.

And I don't see how they'd be violating the ODbL by doing
so.  Besides, even if they *were* violating the ODbL, it's probably
irrelevant, since OSM isn't going to sue them (or anyone) for doing
so.  Furthermore, the license would likely be valid, in the sense that
the fact that they granted it could be used as a defense against
copyright infringement if *they* tried to sue you for redistributing
(etc) the tiles under CC-BY-SA.

On the other hand, I'd say the tiles aren't *really* under CC-BY-SA,
if the underlying data is subject to the ODbL.

Right.  (If your interpretation of the ODbL is correct - which others here
disagree with.)

You are merging two separate events into one when you talk about
distributing a recording under CC-BY, distributing a recording, and
licensing the recording under CC-BY.  The ODbL explicitly allows the
former.  But it is actually silent about the latter.  (It says that
you can't sublicense the score under CC-BY, but it says nothing
about whether or not you can license the recording under CC-BY.)

Ah - so although you are authorized to distribute produced works, those who
receive them may not be authorized to distribute them further.  This may be
the crux of the issue.

From my point of view, I think that is a feature, not a bug.  The extent of

and it is IMHO misguided to try to override the compromise between public and

However that's just opinion.  More interesting is your remark about 'no

That's not exactly the argument.

You can reverse-engineer the produced map tiles.  But one

significant extract of data which you obtained from such
reverse-engineering would be ODbL, to the extent that a) it's

 Right.  But if the music publisher had given permission (perhaps by some

Moreover, a better analogy is that you send *one* friend the entire

You are not infringing the copyright on the produced work, no.

It is not, as with the OS data the licence on the database is expected

Perhaps you are to some extent 'recreating' it by tracing from the Street View
tiles, but that doesn't matter; you have a copyright licence from the Ordnance
Survey to use those tiles, so as long as you don't cheat by looking at the
original database, you can trace and derive whatever you like from them as long
as you stay within the copyright licence granted.


But the ODbL isn't about some platonic idea of a map, this is about the 
precise structure and numbers in the database.



What would prevent us from using an ARR map tile to magically recreate
the original ODbL database?


If I received a printed map 'all rights reserved' and then produced a derived
work from it such as a tracing, I'd probably be infringing the rights of the
copyright holder of that printed map.  On the other hand, if I had a licence
(from a suitably authorized person) to make derivative works and distribute
them under certain terms, I would be able to do that.


And if the proprietary licence said you can do what you like with 
derivatives but you cannot do what you like with the original, how 
would that be different from the ODbL?



If we look at the licencing of My Life In The Bush Of Ghosts, which
licenced individual track elements CC but not the original compiled
work, that's probably closer.



Exactly. And the copyright (or DB right) in the original data is an
entirely separate issue.


Yes - it's quite separate - you do not receive any licence to the original data
but you do get a licence to all copyright interest in the small bit of map
you received; since you have not even looked at the original data you cannot
be infringing copyright in that (similar to 'clean room' rules), and if you do
things with just the extract you received then you are covered by the licence
you received with that extract.


Sure, the licence to the produced work. So how is a substantial portion 
of the original database structure and contents going to be accidentally 
recreated in this scenario?


I don't think it will be possible to accidentally reverse engineer the 
DB, and if you intentionally reverse engineer it, you cannot claim

Clean room rules involve using only uncopyrightable factual data.
There are arguments on both sides as to whether or not tracing a map
constitutes copying only uncopyrightable facts (personally I lean
strongly toward the side that says it does, but I wouldn't be willing
to bet my business on that without receiving substantial legal
advice).

In any case, clean room rules don't apply to database rights.  So if
you live in a jurisdiction with database rights, you can pretty much
throw away that argument.

And it covers all of the copyright for that particular work, not just a subset

Could you clarify what you mean here?  The OpenData release does not include

or the terms under which it is licensed; as far as I am concerned the Street
View tiles are just some image files released under a permissive licence.

granted - but I need not care at all what the terms are of the original DB.

But the ODbL isn't about some platonic idea of a map, this is about the

Ah, no I don't mean the precise numbers, obviously it would be a practical

from different premises: that the tiles can be distributed under CC-BY without

I don't think it will be possible to accidentally reverse engineer the
DB, and if you intentionally reverse engineer it, you cannot claim

OK, imagine the following;
Suppose that some time from now, OSM has moved to ODBL - and a group has 
forked OSM using the last CC-BY-SA planet file - for the sake of argument 
call it OSM-CC.


The original OSM project, with the database under ODBL still releases its 
map tiles on its main website under CC-BY-SA.


Presumably, the OSM-CC project would be well within their rights to use the 
OSM created map tiles as a background layer in JOSM / Potlatch etc. to allow 
users to trace map data. The data created is derived from the CC-BY-SA 
tiles - and so must therefore also be under a CC-BY-SA licence. Therefore 
it's compatible with the OSM-CC project.


With sufficient resources, the OSM-CC project could in theory create a 
substantially similar database to that of the main OSM project - although 
it's extremely unlikely to be identical.

 Yes, that's right, but I also wanted to ask about the other requirement that

 or indeed anything other than ODbL or 'all rights reserved'.

 They can fairly be described as CC because you can exercise all the rights 
 that the CC licence grants you over the CC-licenced work.

When I'm given a set of tiles under a CC license (which disclaims the
database rights in some versions), I think I can justifiably assume
that it doesn't contain anyone else's work under conditions different
from those in the license I was given, unless I'm told so.  So I
should be able to excercise my right to reverse engineer the POIs
names and positions and the streets graph represented by the bitmaps
and distribute the result under a license compatible with the CC
license.

So it should be entirely possible to reproduce most of planet.osm or
at least the useful part of it (so e.g. not the object IDs and not
their order) which would not be covered by database rights or
copyright of OSMF.  For example I could produce z30 tiles with a
public domain mapnik stylesheet and my friend could run a program to
produce a .osm file taking the tileset and the stylesheet as input.


 If you use a CC licenced work to recreate another, non-CC-licenced work, for 
 example if you rearrange it to make the score and lyrics to a Lady Gaga song 
 then record that, the work that you have reverse engineered still breaks 
 copyright despite the fact that you have used a CC licenced work to make it.

Is there any known case that would show that this is how copyright
works?  I'm no lawyer, but copyright is mostly reasonable to me
whereas what you explain would make it unreasonable.

For example say I'm using the CC-BY-SA photographs from flickr to
create a great photo wall, placing the pictures in alphabetical order.
 How do I know that I'm not recreating a differently licensed work by
somebody else, from which all the pictures were cut out?

CC-BY-SA.  And I don't see how they'd be violating the ODbL by doing
so.  Besides, even if they *were* violating the ODbL, it's probably
irrelevant, since OSM isn't going to sue them (or anyone) for doing
so.  Furthermore, the license would likely be valid, in the sense that
the fact that they granted it could be used as a defense against
copyright infringement if *they* tried to sue you for redistributing

On the other hand, I'd say the tiles aren't *really* under CC-BY-SA,

You are merging two separate events into one when you talk about

licensing the recording under CC-BY.  The ODbL explicitly allows the
former.  But it is actually silent about the latter.  (It says that

I don't think that is the important question.  If the OSM project's licence
says that rendered map tiles (or Produced Works, if we assume that the ODbL's
terminology applies in this way) need not be distributed under any particular
terms, then anybody can download the planet file and Mapnik configuration and
make their own tiles released into the public domain.  Since anyone can do it,
it would be silly for the OSM project to choose anything more restrictive.

More important is the licensing for the source data from which the images or
printed pages are generated - what permission should it grant for such derived
works?  And the choice there is essentially 'under the same licence as the
source data' or 'unrestricted'; I don't think much in between makes sense.

Presumably it would help out MapQuest, CloudMade and others if they could
generate map tiles from OSM without having to publish those under share-alike.
And that would probably help the project.  So I'd reluctantly have to conclude
that allowing it is a good idea.  That does jar a bit with the claim sometimes
advanced that we must move to ODbL because it provides stronger share-alike
provisions.

Would it be okay with you if I published my future tiles under a
license that differs from that of openstreetmap.org tiles?

I don't see it would be up to me?  Of course, if I had agreed to license my
map contributions under ODbL then I would implicitly have agreed to that.

But the main OSM site and tile server is a special case.  We should
aim to set a good example.

Yes, and that good example would be public domain.  What would be the point
of insisting on something else, when it can be so easily circumvented by
creating a Tile Drawer instance?

(Unless, of course, as a deliberate step to keep load down on the tile server...
but the kind of people who ignore the tile usage policy would happily ignore
any licence terms as well.)

Is it simplest to keep the tile license the same as it is now rather
than risk compatibility problems with downstream consumers of tiles?

I don't think a change to public domain licensing could cause any
compatibility problem.

 If tracing (a map) is considered copying (and that's a question of law
 which is not exactly clear), then the question is not what in the ODbL
 stops you from tracing, the question is what in the ODbL allows you to
 trace.

 ODbL specifically and explicitly gives you the right to create a Produced
 Work with which you can do whatever you like.

Let's assume, for these purposes, that the person doing the tracing is
not the same as the person who created the Produced Work.  Is that
fair?

What gives the person doing the tracing the right to trace?  Is the
Database copyrighted?  By tracing, are they copying a copyrightable
portion of the Database?  By tracing, are they extracting a
substantial portion of the Database?  If so, what gives them
permission to do that?

 The only restrictions are those specified in 4.3 as quoted above.

The person creating the Produced Work is specifically prohibited from
sublicensing the Database.  So any license granted by the producer of
the Produced Work is not a license on the underlying Database itself.

 If there were other restrictions you wouldn't be able to create a Produced
 Work that was publishable under PD, CC0, WTFPL, CC-BY-SA etc.

You have permission to license the produced work, not the underlying
database.  See 4.8.

Can you publish a Produced Work under CC-BY-SA?  Personally, I don't
think you meaningfully can.  The only semi-reasonable argument I've
heard that you can, came from an ODbL lawyer who basically said, yes,
you can publish a Produced Work under CC-BY-SA, because CC-BY-SA
doesn't apply to databases anyway.

I think Ed Avis is right on that one, though.  It's allowed to make
proprietary, all-rights-reserved
map renderings, but if you want to produce a truly CC-licensed or
public domain one you can't.  (This refers to the no-tracing
restrictions; an attribution requirement is more reasonable.)

 Btw: isn't a rendering a derived database as well?

 A database of pixels?  I would not regard a printed map as a database.
 And neither would I the electronic version of that.

 One could argue about a rendered vector map.

 I think that this distinction is nonsense, a vector map has a certain
 resolution just like a georeferenced bitmap has.

There is no reason for a vector map to have a lower resolution than the
OSM data itself.  But, this is not the point.  The difference to a
bitmap is that a vector image contains descrete objects which someone
could import directly into a database.  So, one could view a vector map
as a database of map objects.

Each .osm file already is a vector map.
