According to  if someone combines non-horizontal layers together, the results must be shared under the ODBL.
From my investigation it appears that the MAPS.ME app  is combining OSM hotels with non-OSM hotels. https://tianjara.net/hosted/maps.me-1.png is a screenshot from the app. Hotel A appears in the app, but as far as I can tell was never in OSM but rather one of the hotels they've added to their app from Booking.com. Hotel B is from OSM. This is the area https://www.openstreetmap.org/#map=18/-33.87758/151.20447 There are other examples of this too like this hotel https://www.openstreetmap.org/way/196622136 which in the app shows up next to their supplemented data like this https://tianjara.net/hosted/maps.me-2.png Am I correct that in order to be complaint with the license MAPS.ME either need to make this data available under the ODBL or remove all OSM hotels from their app?  http://wiki.osmfoundation.org/wiki/License/Community_Guidelines/Horizontal_Map_Layers_-_Guideline#Examples_of_where_you_DO_need_to_share_your_non-OpenStreetMap_data  version 6.2.2-Google Data version: 160621 _______________________________________________ legal-talk mailing list firstname.lastname@example.org https://lists.openstreetmap.org/listinfo/legal-talk
