6.4 Open source and creative commons

Open source and Creative Commons have revolutionized software development and content creation. These movements promote collaboration, transparency, and free sharing of knowledge, challenging traditional proprietary models.

Open source licenses and Creative Commons provide legal frameworks for sharing while protecting creators' rights. These systems have fostered innovation, reduced costs, and increased access to technology and cultural works across various fields.

Origins of open source

• Open source revolutionized software development by promoting collaboration and transparency in code creation and distribution
• Emerged as a response to proprietary software models, emphasizing freedom and community-driven innovation
• Shaped modern technology landscape by enabling widespread access to powerful tools and fostering a culture of shared knowledge

CC license elements

• Attribution (BY) requires credit to the original author
• ShareAlike (SA) mandates derivative works use the same license
• NonCommercial (NC) restricts commercial use of the work
• NoDerivatives (ND) prohibits creating derivative works

CC0 and public domain

• CC0 waives all copyright and related rights to a work
• Enables creators to dedicate their work to the public domain
• Facilitates unrestricted use and reuse of content (scientific data, cultural heritage)
