US copyright law has a creativity requirement. Just how much "creativity" is required is ambiguous. European copyright law typically has a "seat of the brow" component, which means under European Copyright law, it would copyright. (That EU directive doesn't throw out copyright on "sweat of the brow" grounds.) > Positions and movement parameters of celestial bodies, presented in their natural form (to keep the use of JPL-DE data as example) are bare The creativity here is: * Which bodies are included; * How frequently are the co-ordinates listed - hourly, daily, weekly, monthly, annually, etc.; * What unit of measurement is used for those co-ordinates; * What is the starting point of the listings; * What is the ending point of the listing; > A (US) court decision that compilations of facts requires a minimum of > originality to be copyrighted (in that case it was a telephone book; a > time-sorted list of planet positions is the same). Astrolabe, Inc. v Arthur David Olson and Paul Eggert Massachusetts District Court 1:2011cv11725 implies that a case to the contrary can be made. > Is this enough material to claim an exception? Nope. Still doesn't cover those judicial domains in which "public domain" is not a legally recognised thing. What is needed is a specific license for the JPL Planetary Ephemeris, that is congruent with the Debian Social Contract. I am not a lawyer. This is not legal advice. jonathon
