Hey ldb, GNUtian dak means "GNU-derived" (see unwritten GNU Copyleft Act). It has really nothing to do with software "derivative works" under copyright which protects software as literary works modulo the AFC test. http://digital-law-online.info/lpdi1.0/treatise27.html ------ Some have claimed that an application program that needs a library for its operation is a derivative work of that library. They take that position because the application program is based on the library because it was written to use the subroutines and other aspects of the library. Such a position is misplaced. [...] It could be argued that the component program really does include portions of the library that it uses data structures that are passed as parameters, or even the parameter lists themselves. But elements dictated by external considerations are filtered out when trying to determine whether there is copyright infringement. No other conclusion makes sense. If it were not the case, then any program using the applications program interfaces (APIs) of an operating system could be considered a derivative work of that operating system. And, under the exclusive right to prepare derivative works, the copyright owner of an operating system such as Microsoft Windows could control who was allowed to write programs for that operating system. ------ Same author also wrote this: ------ One can tie oneself in knots trying to make sense of the GPL and the statements made about it. It ignores provisions of the copyright statutes that allow the modification or redistribution of works without permission of the copyright owner. It talks about "derived" works which don't seem to be the same as "derivative works." And the explanations from RMS and others often make little sense, as in the case where something was a derived work until somebody wrote a non-GPLed math library compatible with the GPLed one. ------ Consider also http://www.catb.org/~esr/Licensing-HOWTO.html <quote> consider the case of two scientific papers which reference each other. The fact that paper B calls paper A (references it for support) does not make B a derivative work of A. This remains true whether B and A are published together in a symposium (analogous to static linkage) or separately (analogous to dynamic linkage). Computer programs are defined in 17 USC as literary works </quote> Note also that exclusive distribution right is severely limited by "first sale". Finally, regarding ESR's statement "FSF has stated its willingness to go to court for this position", don't believe it. http://novalis.org/talks/lsm-talk-2004/slide-31.html <quote copyright=Free Software Foundation> Don't go to court FSF hasn't. Court is expensive Judges don't understand technology "Is static linking like two icons on one desktop?" -Judge Saris, MySQL v. Nusphere oral argument </quote> Translation: the FSF doesn't really believe that they could fool a judge into buying http://web.novalis.org/talks/compliance-for-developers/slide-49.html [begin textual copying copyrightFree Software Foundation] July 27, 2004 GPL Compliance for Software Developers Legal notes ---------------------------------------------------------------- Legal notes Static linking creates a derivative work through textual copying Most dynamic linking cases involve distributing the library Still a derivative work: Dynamic linking Distributing only the executable (testtriangle) Still a derivative work: Distributing the source code of software which links to a library [end textual copying] FSF's "legal notes" idiocy. regards, alexander. _______________________________________________ gnu-misc-discuss mailing list gnu-misc-discuss@gnu.org http://lists.gnu.org/mailman/listinfo/gnu-misc-discuss
