Any tangable "creative work" is copyrighted by its author in all countries which obey the Berne convention. In the US you can revoke copyright by stating you are putting the work in the public domain. This notion does not exist in some other countries, so it is best to just keep the copyright and then release your contribution under a license consistent with the other contributions. Some people prefer to use the modified BSD license for their code, which is fine too. This allows us to redistribute your code and modify it (for example, in case you quit the project and bugs are found down the road). > > On Apr 14, 9:45 am, mabshoff <[email protected] > dortmund.de> wrote: >> On Apr 13, 4:40 pm, Rolando <[email protected]> wrote: >> >> Hi, >> >> > Is it possible to make a contribution of code to Sage which has no >> > license and no copyright? >> >> No, it should be licensed in a GPL V2+ compatible way. >> >> > The Sage Programming Guide seems to suggest that copyright should be >> > given to yourself and William Stein. >> >> No, you should retain copyright yourself, there is no reason to give >> copyright to William. >> >> Cheers, >> >> Michael > > > --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
