OK, so tools like BadMap show me a heap of data which will be affected/deleted in my area when the new licence takes effect in a couple of months. What do I do about it? These are streets I know and ride my bike down regularly I don't feel like I have to go and 'survey' them with a GPS, I know they exist, I know their names. Do I simply delete the existing 'bad' ways and draw in my own 'good' ways? What about a way that was created by a decliner, but since edited by accepters, am I able to copy the information provided by accepters to my new way? I'd really appreciate a bit of a step-by-step guide to the best/most efficient ways of tackling the repair job post April 12. --edit-- Actually, I've just learned about the fosm.org fork (slow, I know!), where current data will still be viewable. So, if it's CC-A-SA, and I go and get information from it, and I attribute the source in my changeset, is that not OK? What if I only copy data added by 'accepters' and ignore that made by 'decliners'? Data that should be preserved, but would be 'lost' because it built on the work of a 'decliner'? I struggle to understand the intricacies, I can't be the only one. Someone needs to provide some clear direction here. asked 17 Jan '12, 23:48 woowoowoo |
First of all, you have to understand that the administrators will remove data from Odbl/Contributor Terms decliners and you cannot re-introduce them afterwards yourself. Second, there is a wiki page about remapping the data here : http://wiki.openstreetmap.org/wiki/Remapping > Do I simply delete the existing 'bad' ways and draw in my own 'good' ways? > am I able to copy the information provided by accepters to my new way ? > FOSM : I go and get information from it, and I attribute the source in my changeset, is that not OK? > FOSM : What if I only copy data added by 'accepters' and ignore that made by 'decliners'? answered 18 Jan '12, 09:21 Pieren OK, thanks - very helpful - exactly what I was looking for. Strange that my searching didn't turn it up!

From what I know the main reason to remove data contributed by users who did not agree to odbl/ct is not the licence, but the CT. Whether you can or cannot use the old (CC-BY-SA licenced) OSM data is a different, more general question - Can you use any CC-BY-SA data as a source? CC-BY-SA does not protect the database itself (that is the reason for ODBL). What is protected by it is the graphical representation. The BY part of the licence is easily fulfilled by attributing the source, SA excludes some use cases ad therefore makes CC-BY-SA incompatible as a source. That means you cannot directly use the graphical representation (copyrightable, licenced under CC-BY-SA). Yet another question is, whether or not you can use the data ("a road goes prom place A to place B, let's transfer that information"). That depends on the jurisdiction and would require more complex analysis... Short summary: What prevents you from using that data is mostly likely not copyright or any other law, but OSM's super careful policy regarding data use. answered 18 Jan '12, 11:32 LM_1 "without the need for CT users specifically agreeing." This is not true. Any odbl/ct license change requires an agreement of the OSM foundation and 2/3 majority vote of the active contributors (section 3 of CT's). The main difference with the current situation is that if the change is accepted, all data is migrated to the new license even for those contributors who refused the change.

That is what I meant. If 2/3 active mappers agree then all contributions (non-active, 1/3 of active) will be re-licensed. Agreement of any specific user is not required (unlike now).

Sorry for highjacking this question with an "answer", which is merely a follow-up question. I am a little shocked, that the fact, that much info might be deleted in several months, is not very well made clear on the main page. In fact, I heard about that for the first time now. Will there be a central effort to contact "decliners"? Or should the local community do that? What if there is no local community? I am mapping in Georgia, and we are first of all only a small bunch, and second, prefer to add new map features instead of putting much effort into re-mapping big parts of the country. answered 20 Jan '12, 10:05 moszkva ter I think the effort to contact decliners and an action plan is provided on the remapping page: http://wiki.openstreetmap.org/wiki/Remapping however, it could be more streamlined.

Re who/what/when/how, most of the answers to that are on the http://wiki.openstreetmap.org/wiki/Remapping page. Mappers who have not yet accepted the CTs will have had emails sent to the address that they have registered at OSM, but that may not still be valid of course. Other people have tried to track them down via other means, such as social media. I'd be tempted to start by contacting the rest of the local community and using the tools on the Remapping page to see who the priority mappers to contact are and see what may be lost.
