There's a license FAQ [1] which I think should answer your question. whether your POI data is derived work would depend on whether you use OSM data to place those POIs. I presume you have them already in some database however and just wish to use OSM as a backdrop, in which case that would be considered a separate dataset.
Any modifications to the OSM data itself however would need to be published as the CC-BY-SA dictates. 1. http://wiki.openstreetmap.org/wiki/Common_licence_interpretations _______________________________________________ legal-talk mailing list legal-t...@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
