Hi all, I ask myself a question about specialised proprietary format database used in some applications like by example smartphone routing applications. Quite often these applications propose you to dowwnload some map files if you want to use them Offline. The issue I see with this is that user is dependant of the application provider for map update or scope cover by map extract. I looked at this page : http://wiki.openstreetmap.org/wiki/Open_Data_License/Trivial_Transformations_-_Guidelineand especially part called Specialised (e.g: mobile) format databases
It is said that this is a trivial transformation and that format could be kept closed if data is also provided in an open format. Ok but how to be sure that data provided in Open Format is exactly the same than the one contained in closed format ? by example how to check that non-OSM data have not been included in closed format ? To make a parallell ( perhaps wrong ), GPLv3 requires that someone providing a binary using GPL code must provide the source code ( including modifiactions if any ) eveything needed to rebuild the binary. "Both versions of the GPL require you to provide all the source necessary to build the software, including supporting libraries, compilation scripts, and so on. They also draw the line at System Libraries: you're not required to provide the source for certain core components of the operating system, such as the C library." source: http://www.gnu.org/licenses/quick-guide-gplv3.en.html and "GPLv3 stops tivoization by requiring the distributor to provide you with whatever information or data is necessary to install modified software on the device." Do the ODBL requires the same for a closed format including OSM data ? or more clearly does it require that application provider also provide the tool used to perform the conversion between OSM data and closed format ? If yes, by consequence this would allow user to be independant of application provider and to regenerate by itself the maps directly from OSM data. If this topic has already been covered somewhere sorry and I'll please you to provide me some pointers to the discussion Thanks by advance for you answer Cheers Julien _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
