Btw, what we generally do here is to extend the copyright timestamp, instead of just replacing, like: Copyright (c) 2012-2014 > > > I'm a bit confused about the copyright year and author.

The copyright laws were written to cover all sorts of intelectual work, and were written originally to cover music, painting, literature work. There are actually two kinds of copyrights: moral rights and economic rights. The GPL license (and all other sorts of licensing) deals with the economic rights. A copyright line, however, can, IMO, serve for both purposes: to tell the authorship and to identify who owns the economic rights and who is licensing them under GPL. If you develop something under your work contract, your employer likely has property rights. Yet, you still owns the moral rights[1]. On most Countries, it is not even possible to transfer them to someone else. [1] http://en.wikipedia.org/wiki/Moral_rights That warrants that a book written by, let's say, Julio Verne, will always be copyrighted by him, no matter if he (or his family) sold the economic rights, or if his books are already in public domain or not. > And why is it useful who owns a copyright and when the copyrighted work > was produced?

The moral rights, however, never expire: if someone uses part of the Illiad (written around the 8th Century BC by Homero) on his work, he can't claim any rights on it, because that part of the text will forever belong to Homero. > > > Bjørn > -- > To unsubscribe from this list: send the line "unsubscribe linux-media" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- Regards, Mauro -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
