    Creative Commons Share Alike licenses are:

    Like all Share Alike licenses anyone who extends and improves the material must re-release it under the same license exactly with no variation in terms. This is similar to Share Alike provisions in GFDL and GPL. Note: the definition of open source explicitly does NOT require share-alike terms so it is simply wrong to assume that open content necessarily is open source.
