[OSM-legal-talk] Licensing implications when extending POI with external metadata

[Joao Neto]

Hi,

I'm planning to develop an Android application that displays OpenStreetMap
POIs near you and complements the OSM data with data coming from other
sources (address, phone numbers, user notes, etc.).
What are the license implications in doing that? Would I have to expose the
combined data under the ODbL? Would that be considered "derivative work"
even if I don't change the OSM data or keep the two databases "physically"
apart and use only references?

Please advise.

Thanks,
Joao
