Unit 2. Creative Commons licenses concepts

2.4. Using Creative Commons licenses (authors and users)

This section introduces additional information about the use of CC licenses: the three levels of the licenses (legal system, humans, and machines), and the use of licenses by authors and final users.

2.4.1. Levels of CC licenses

CC licenses can be used in three different levels.

The lower level would be the detailed legal wording attached to each of the licenses. This helps when applying the licenses in a given country and legal system, in case of litigation.

There is of course the human readable level of the licenses, in which the licenses can be read and easily understood by humans.

The machine level refers to the fact that the licenses can be embedded into metadata within the works themselves. This allows computer software (such as crawlers and search engines) to use license information and help users find the works needed.

2.4.2. CC licenses for authors (licensors)

When creating a work, an author should choose a license for it, stating which are the uses wanted for the work. CC licenses are an easy way to license because they are general, cover the most usual cases, and are easy to understand.

However, the author retains legal control upon the work, and the licenses are valid under IP law (they are mapped to the law of each country).

In any case, the licenses are oriented towards the free culture movement, encouraging the use and sharing of the work.

2.4.3. CC licenses for users (licensees)

CC licenses have also many advantages for users. Any work uses one of the only 6 common licenses, and the licenses are easy to understand. Therefore, it is much faster for the user to decide if a work can be used or not (no need to read a different license for each work), and it is easy to find legally valid resources to use. In fact, there are many search engines for resources that can use CC license information to filter the results.
