Creative Commons

Creative Commons (CC) is an international no-profit organisation that provides a system of free licences for managing copyright. These licences allow creators, artists and academics to legally share their works, permitting others to reuse, modify and distribute them. It positions itself between traditional copyright ("All rights reserved") and the public domain ("No rights reserved"), following the principle of "Some rights reserved".

What it's for / why it's important

Creative Commons licences serve to facilitate the spread of culture and knowledge. They allow authors to communicate in a simple, standardised way which rights they reserve and which they waive. This is fundamental because it exponentially increases the quantity of content (photos, text, music, videos) available for legal reuse, promoting collaboration and innovation without the user having to ask for explicit permission every time.

When it's used / in what context

A creator uses a CC licence when they want to encourage the distribution of their work. It is a system used globally in academic contexts (for publishing research in Open Access), artistic settings (photographers on platforms like Flickr), and for educational and informational purposes (it is the basis for portals like Wikipedia). A user (such as a blogger, designer or student) searches for works with a CC licence when they need material to integrate into their own projects without infringing copyright.

Practical example

A photographer uploads one of their images to a site and licences it as CC BY-SA. This means that anyone can download that photo, use it in a blog post (even a commercial one) and even modify it. The user has only two obligations: they must credit the photographer's name (the BY - Attribution clause) and, if they modify the photo and distribute their version, they must do so under the same licence (the SA - Share Alike clause).
