The State of Open Data: A Decade of Progress and Challenges, is a special edition that looks back across ten years of findings.
This year’s report highlights where real progress has been made, where momentum has stalled, and which new pressures and opportunities are reshaping the future. What began as a push for openness through advocacy and declarations on open access, has evolved into widespread adoption, and in some countries, formal mandates, driving a global shift towards openness.
- The first section explores the current state of open data based on 2025 survey findings and long-term trends, highlighting major shifts and ongoing challenges. The data tells a story of growing awareness and engagement with open science principles, alongside persistent barriers to implementation.
- The second section of the report brings together perspectives from researchers, librarians, and data experts to show how policies translate into practice. Their insights reveal cultural, infrastructural, and disciplinary nuances behind the numbers, and what the next decade of open data may require.
- Recommendations: The report finishes with three key actions to accelerate progress in open data.
Looking ahead, the challenge is not convincing researchers of the value of open data - it is ensuring that sharing and reuse are supported, incentivised, and embedded into everyday research culture. The next decade must focus on operationalising these principles so that openness is not an extra burden but the default, efficient, and most beneficial path for research and society.
