This depends on the license, for example, if it is CC-BY,you do not need to include a license, if it is CC-BY-SA you have (SA=share alike). BY is always implied by CC type licenses. GPL requires you to include a visible statement in each file, also, the full text of the GPL in a file and so on. Other licenses are much less restrictive. It also depends on the media, e.g. sagemath.org is CC-BY but it doesn't start by stating this ;) > > Lastly, if an individual licenses under CC-SA, can some else then use/modify > their work under CC-BY-SA? Afaik, there is no CC-SA, BY is always implied! > It seems like a standard in the Sage community should be > advocated to avoid conflict. Probably the best is to encourage everybody to think about licensing its creative content. Maybe it is a nice idea to add a license field to the published notebook. I.e. when you hit publish, you can select from licenses in a drop-down menu (default: proprietary) ... This might be such a standard? If somebody else thinks this is a good idea, it could be worth posting to the sage-notebook mailing list.
