[OSM-legal-talk] Attribution/Licensing for map derived from Standard OSM TIles

[Kathleen Lu]

You can publicly disclaim rights in the parts you contributed, while
indicating the required OSM attribution.
Think of it this way: If you were to get a bunch of CC-BY photographs
and put them together in a slideshow, you could, in theory, add a
requirement for attribution for yourself, for ordering the slides in a
nice way. But you can't say the slideshow is all CC0 or public domain,
because then you'd be erasing the CC-BY license and attribution on the
original photographs. You'd say something like, "original photographs
CC-BY..." You could add "I disclaim any rights in my ordering of the
photos."

If this really is a map of directions to your house though, I'd say
you're overthinking this. Who'd want to copy it anyway?
