Talk:Share Alike
I hope this is the right place to ask for this... Could a paragraph be added to this article to clarify what exactly it means if content is published using a CC license that does not contain the "SA" clause?
For example, if content is licensed as CC-BY, can a derivative work be licensed as CC-BY-SA (thus "adding" a clause)? If content is licensed as CC-BY-NC, can a derivative work be licensed as CC-BY-SA (thus also "removing" a clause)?
The layman reasoning here would be that, because of not explicitely stating that a derivative work needs to use the same license (=share-alike), it could use a similar one instead. If this can't be done, then what is the exact additional benefit of making "SA" explicit? -- CidHighwind 20:33, 25 December 2009 (UTC)
