The recent emergence of generative artificial intelligence (AI) has had a phenomenal impact on CHIs, especially as the content they steward is accessed and used for AI development. One key question centers on the conditions, norms, and expectations governing the use of openly licensed and public domain cultural heritage materials as data for AI development.

As the United Nations General Assembly (UNGA) convenes its 81st session in New York in September, Creative Commons is bringing together leading civil society and digital rights organizations for “A Conversation on Collaboration,” a day-long symposium examining how to balance digital sovereignty with open collaboration.

We are excited to announce that we will be supporting four regional events for CC’s 25th Anniversary—representing regions around the world with groups who are working to advance open knowledge. We’re delighted to be working with a variety of trusted partners and look forward to sharing more about their plans and reporting back on how these events went. 

With both Wikipedia and Creative Commons turning 25 this year, our participation in Wikimania 2026 felt especially meaningful. A quarter-century in, both organizations have evolved from scrappy experiments to global infrastructure. Our community has grown through a shared commitment to openness, access, and knowledge. The weeklong conference reaffirmed that commitment as AI is reshaping how we access knowledge and share online.

Attribution has always been a cornerstone of working with other people’s creativity and knowledge. As Creative Commons reminds us, practicing attribution serves many important functions, from providing verifiable evidence of a claim, to paying respect to the work of others, and creating pathways for traffic and financial value to flow. Despite the importance of attribution, many of today’s AI systems fail to acknowledge the sources of knowledge and creativity that make them possible.

The Creative Commons Open Heritage Companion is a practitioner’s guide developed to help cultural heritage institutions navigate the journey from closed to open collections. Grounded in the legal, policy, and ethical questions institutions face along the way, the Companion brings together resources, tools, and examples that guide practitioners from their first questions about openness to leading the field.

At the recent Founders Fireside Chat, Creative Commons founder Lawrence Lessig referred to himself as “hopelessly naive.” It struck me that this sort of naivete—the kind that is about believing in the potential for good when sharing knowledge with other humans—is the glue that holds the entire Creative Commons movement together, across borders and belief systems.

Over the past 25 years, Creative Commons has helped transform openness from an aspiration into a global practice. Through open licensing, communities around the world have built new models for sharing. The Legacy Of series reflects on four interconnected movements—Open Access, Open Education, Open Science, and Open Culture—and the people who helped shape them.

Twenty-five years ago, a small group of people made a bet. They believed that if you gave creators a simple set of tools and licenses in language that a lawyer, a machine, and a human could all read, millions of people might choose to share their work with the world instead of locking it down.
“We said, oh gosh, if a million people use these licenses, that would be amazing,” Hal Abelson recalled, laughing at how small that ambition sounds now. Today the number “starts with a B.” Hal’s quote was one of many memorable moments during Creative Commons’ Founders Fireside Chat, a special benefit event for CC’s 25th anniversary.

In this post, we outline our plans to build upon and strengthen CC signals in order to support our goal of sustained access to human knowledge. We do not have all the answers yet. What we do have is a framework for how we will work toward them.
