What is an attribution license?
Within the context of the Creative Commons, an attribution license is one of the six main types of creative commons licenses. As explained by the Creative Commons: “This license lets others distribute, remix, tweak, and build upon your work, even commercially, as long as they credit you for the original creation.” Thus, this license is the least restrictive of the creative commons licenses, since the user can create derivative works (and need not use the same license) and can use the original work or the derivative work for non-commercial as well as commercial purposes. The only major restriction placed on the user is that there must be proper attribution to the original author.
An attribution creative commons license can be indicated by the use of the “by” graphic.
