Hi Jukka, although I'm curious about an answer from someone who's more competent in the legal things, I'm not sure with your argument here.
ODBL does not require Share-Alike for produced works. The map, even when based on OSM data is a produced work. Therefore even if the map is based on osm data, it's not share-alike, and any data based on the map IMHO cannot be share-alike too. Let's assume the opposite: - The map is a produced work and may be published on any license (more restrictive as well as more open than ODBL), so let's assume the map is CC-BY (without Share-Alike), - Then from CC-BY it follows that anyone could derive other stuff from that map without being obliged to follow any share-alike clause. So if anyone would require data gathered on top of an osm map to be share-alike, he's wrong (or ODBL contradicts itself in this example in some way). As I assume the ODBL to be checked many times, I assume yet that therefore your implication chain to be wrong and new data collected on top of an osm based produced work is not tainted with share-alike from ODBL. Nevertheless I am not a lawyer, so someone else may proove me wrong If I am. You mention Google Maps as a possible alternative to prevent this problem. I disagree here, too. If you're talking about a substantial amount of data derived from (or above) an OSM based map, the same would be forbidden with google maps data, too. As the terms of service of google state (German version): "Sofern Sie zuvor keine schriftliche Genehmigung von Google bzw. dem Anbieter der betreffenden Inhalte erhalten haben, dürfen Sie (a) den Inhalt weder ganz noch teilweise kopieren, übersetzen, abändern oder abgeleitete Werke daraus erstellen" translated by me: "without written permission of Google or the affected data providers your are not allowed to copy (in parts or as a whole), translate or modify the content or produce derived works from it." Therefore the same as for OSM holds for any content of Google Maps, and you probably should think about using Google as an alternative from a legal point of view. regards Peter Am 14.03.2014 14:17, schrieb Jukka Rahkonen: > Simon Poole wrote: > >> One thing I would like to hear about in this context of this discussion, > are examples of concrete use cases that are not happening because of > share alike and that are in general things that the community would like > to support (so not "evil corp can't take the data now and keep it"). > Concrete in the sense that they are uses that really would happen if > share alike would be dropped, not "we can build a straw man that shows > how bad share alike is". > > Hi Simon, > > We have considered that we cannot use OpenStreetMap as a background map in > any of the applications where users are sending location aware information > back to administration.
