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.

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.

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.

It would, of course, require that nobody had added bits of Gaga-music to the OSM database without prior permission from the record company. If we do, the original rights still apply to the recreated work. CC licencing is not a way of circumventing that. The point is this. The CC text says that it grants you a copyright licence in the work. Clearly, Well, not clearly. CC licences don't cover what they cannot. that applies to all copyright interest in the work and not selectively to just the pictorial part of it (even if that concept existed). If you follow the terms of the licence, you are not infringing copyright. You are not infringing the copyright on the produced work, no. If you're familiar with the Ordnance Survey OpenData release in the UK, it's exactly the same situation. The original OS master database is copyrighted. It is not, as with the OS data the licence on the database is expected to apply directly to derived works. 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?

Rob Myers r...@... writes: The point is this. The CC text says that it grants you a copyright licence in the work. Well, not clearly. CC licences don't cover what they cannot. Yes - but the licence does cover copyright in the particular work that you received (in this case a printed map, say). That is what I want to establish. And it covers all of the copyright for that particular work, not just a subset so that you're granted a licence to the pictures but not the words. It doesn't, obviously, cover anything not contained in that work. So it couldn't possibly include the exact tags used in a landuse=brownfield area - just the shape of the area and the fact that it is brown. If you're familiar with the Ordnance Survey OpenData release in the UK, it's exactly the same situation. The original OS master database is copyrighted. It is not, as with the OS data the licence on the database is expected to apply directly to derived works. Could you clarify what you mean here? The OpenData release does not include any access to the original database. I have never seen the OS's master database 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. If I trace from them and make a derived work, I need to stay within the 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 precise structure and numbers in the database. Ah, no I don't mean the precise numbers, obviously it would be a practical impossibility to recreate the exact database and if somebody did that you would suspect that they had been peeking at the original DB all along. I just mean the subset of the information that is recoverable from the tiles. 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? Perhaps it wouldn't be different, but that is not what happens here. You don't receive the map tiles under ODbL. You receive them under CC-BY, shall we say, without additional restrictions. If that is the case, then you can make derivatives such as tracing and distribute them under the licence terms you received. 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 am only referring to tracing from the map tiles themselves. Perhaps you are right that it would be practically impossible to recreate the original database from that - in which case we come to the same conclusion, albeit from different premises: that the tiles can be distributed under CC-BY without additional riders, and people can freely trace over them to make their own CC-BY licensed map.

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 independent creation. 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. ___ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk

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?

If you are able to reconstruct a database with substantial parts of the original database by re-engineering if from the map, you must admit that the database somehow still was in the map. Otherwise you could simply create a SVG-Map, publish it under PD, recompile the db from the svg and you would have circumvented the license. The first version of ODbL hat an explicit clause about reverse engineering, saying that if you reverse engineer a produced work the resulting DB will fall under ODbL. That has been scrapped because lawyers said that this was implicit - i.e. you *can* indeed have a produced work that is, say, PD, but if you use that to re-create the database from which it was made, that database is protected by database right once again and you need a license to use it. Otherwise, only the most obscure works (certainly not a printed map) could fall under the Produced Works rule.

Ed, do you have a preferred future tile license? 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?

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.
