Unit 2. Creative Commons licenses concepts

2.2. Creative Commons licenses

CC licenses are somehow inspired by the Open Source Software movement, especially by the GNU GPL (General Public License) developed by the Free Software Foundation.

The licenses are valid under copyright law internationally, although there has to be a mapping from the licenses to the particular law of each country.

There are 6 types of licenses. The user chooses one of the six depending on 4 different rights: attribution, non-commercial, share alike, and no derivatives.

A user can use the original work protected by a license for anything he or she wants, share the work with others, etc. as long as the limits expressed in the CC license are met.

2.2.1. (CC) Attribution

Attribution states that the person (the licensee) can use the work protected by the license, but has to give credit to the author (and possibly comply with more conditions).

That is, the user has to attribute the work he or she is using to the author (credit/cite). The correct way to attribute works under a CC license will be the treated in another unit.

This right is mandatory. Therefore, all uses of a CC licensed work must attribute the author (except if the author explicitly chooses otherwise).

 
2.2.2. (CC) Non-commercial NC

Non-commercial means that the author only allows to use the work for non-commercial purposes. The problem is that deciding whether a purpose is “commercial” or not is quite vague. In Creative Commons terms, it is defined as:

“primarily intended for or directed toward commercial advantage or monetary compensation”

 
 
2.2.3. (CC) Share Alike SA

New works can include or modify other works. An author chooses Share Alike when the wants that all the works that use his or her original work keep the same license used for the original. For example, if a photograph is licensed as Attribution – Non Commercial –Share Alike, a book that uses that photograph must be licensed likewise. That is, the book can not have commercial purposes (sold). You can use it in your own work, but only if it is licensed with the same license.

This is also known as the “viral clause”, because the license for the original work “infects” any other work where it is used.

 
2.2.4. (CC) No derivatives ND

No Derivatives means that the author disallows any modification made by others to his or her works. The work must be used as is, but can not be “touched”.

You can not make derivatives from the work (remix, adapt, change, etc.). For example, a graph could be used in a new work, but the graph should be in its original form. No changes to the graph are allowed.
