[OSM-legal-talk] Usage of OSM URLs in combination with proprietary set of URLs

Hello Gian and Sandro,
IMO, from an ODbL it is definitely okay or you to extract URLs and crawl
them, and publish the crawled data (though you'd need to attribute OSM for
the URLs).
But if you are combining OSM URLs with proprietary URLs, and then
publishing both, then there's the question of whether you are making a
derivative database that would mandate sharing back your proprietary URLs
(making them available under a compatible license to be added into OSM).
Your use case is not really a map one, so it's a rather odd scenario. I
think the safest course would be to make the rest of the URLs available
under a compatible license (e.g., ODbL).
