[OSM-legal-talk] Use of OSM in closed commercial software / License / Copyright?

[Vincent Veldman]

If you plan to mash up OSM data with your own (not OSM) data in your product, I believe you are obliged to contribute your data back to OSM. I might be wrong, but this is my understanding of the license. 
 


That's not exactly true - or in two words:"It depends"

If you apply the concept of collective database, then the OSM data remains under ODbL obviously.
Your own data you can release under any license you like.

https://osmfoundation.org/wiki/Licence/Licence_and_Legal_FAQ#1.9._Can_I_charge_for_distributing_OSM_data_or_data_derived_from_OSM_data?

please read on "Collective Database" that's how you solve any issues on licensing mixing.. basically you don't mix anything.

For more specific information read
https://osmfoundation.org/wiki/Licence/Community_Guidelines/Collective_Database_Guideline_Guideline
https://osmfoundation.org/wiki/Licence/Community_Guidelines/Regional_Cuts_-_Guideline
https://osmfoundation.org/wiki/Licence/Community_Guidelines/Horizontal_Map_Layers_-_Guideline

to understand the nuances and how to implement it properly.

But you can write your software, to maintain 2+ databases strictly separated multi-layers to the end-user and then the OSM part remains ODbL and the rest - whatever it has to be..


that's my understanding of the articles I mentioned above
