This is an except from a message I sent to Steve. But hopefully someone can answer these questions for me (and for everyone who wants to comply with the ODbL):
"If you publicly use any adapted version of this database, or works produced from an adapted database, you must also offer that adapted database under the ODbL." How long do I have to keep a copy of the adapted database in case someone takes me up on my offer? How much of the database do I need to keep? Is the offer valid to third parties? If person A makes a bunch of tiles from a database, and person B prints out a map from those tiles and gives the map to person C, who offers person C the copy of the adapted database? (Person B likely doesn't have a copy, but Person A would have to keep a ton of obsolete data indefinitely if his offer is valid to third parties.) As of right now I have produced hundreds of thousands of tiles from a myriad of different versions of a myriad of different databases. If someone asked me to give them a copy of the adapted database, I couldn't possibly comply. _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
