I understand you indicate towards: > Thus, an OSM dataset used in combination with a non-OSM dataset will be > considered a Collective Database, and will not trigger share-alike when: > the non-OSM data adds a particular type of geometry or data for a primary > feature that was not already present within a regional cut, and the added > feature data includes no OSM data; 1) We are not sure, if the new polygons somehow derive from OSM data. If the polys are either trivial or completely non-OSM, they add a geometry, not already presend and includes no OSM data. Therefor it will not trigger share-alike. #trivial To my eyes the polygons seem to be roughly drawn from OSM data and in other cases arbitrarily – possibly derived from local knowledge. You can find german comments, rather generic ones. These independently drawn partitions of land seem to reflect somewhat inaccurate or rather vague estimates of various properties, such as noise pollution, quality of view or perhaps some worth estimates. I could not see anything that is verifiable, according to OSM standards. But I may be very wrong. At a quick glance this seems trivial and of little use for OSM. Perhaps if those scores represented paid prices or actual rents the polys would somehow become data about something. But I couldn’t find any indication for that. 2) Those scores add a type of data for a primary feature not present in OSM and includes no OSM data already. So, as Kathleen already pointed out, they quite probably won’t trigger share-alike. Maybe the scores are calculated from other OSM features in some fashion and is therefor somehow already present in OSM. But I don’t see how. _______________________________________________ legal-talk mailing list legal-talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/legal-talk
