Translations:Help:Changing your wiki license/8/en

There are a few versions of Creative Commons, with traits that can accumulate and combine. The traits are:
 * BY - Attribution
 * This means that the author of the text is mentioned in the credits somewhere. In wiki software, this is usually automatic: you can click the "history" tab.


 * SA - ShareAlike
 * This makes the license viral: Every edit that builds on your page must use the exact same license.


 * ND - NoDerivs
 * No one is allowed to make a derivative work—the text must be redistributed verbatim. This license is not terribly suitable for wikis because each edit is a derivative work.


 * NC - NonCommercial
 * The work may be reused, so long as it is a non-commercial use. This typically means you can't make money from selling someone else's work—but this is a rather nebulous concept.


 * 0 - Zero
 * This is a special license that places an item into the public domain, or as close as possible to being worldwide. This gives away all ownership possible to the whole world.
