The fifth edition of OSFair will be held from 15th to 17th September 2025 at the CERN Science Gateway in Geneva, Switzerland, hosted by the CERN Open Science Office and co-organised with OpenAIRE.

This year’s Open Science Fair will explore how diverse forms of collaboration can accelerate discovery, enhance knowledge accessibility, and create a more transparent and equitable research ecosystem. By fostering open and inclusive cooperation across continents, we can build a stronger, more connected scientific community.

The OS FAIR welcomes all actors of the research communities and infrastructures, including: librarians, repository managers, content providers, service providers, research administrators, facilitators of research, learned societies, publishers, policy makers and funders, citizen science groups and initiatives, and innovators in scholarly communication.

Conference Topics

We invite you to share updates and developments on open science initiatives within your organisations or countries / regions. ‘Open Science’ encompasses a range of elements, including established practices like open access to research outputs (such as publications, data, and software) and emerging aspects like open research methods, open evaluation, societal engagement, citizen science, and more. Successful proposals will make issues around collaboration explicit, for example: what can collaboration between various stakeholders, services, and infrastructures look like, and how can collaboration be enabled and facilitated?

You are encouraged to discuss and highlight practical experiences (both positive and negative). The presentation of demonstrations and prototypes are welcome.

Your contribution should be aligned with one of the main conference topics:

• Impact and Monitoring of Open Science
• State of play of Open Infrastructure
• Training, Skills, Awareness
• Reforming Research Assessment

More information about the conference topics can be found here. There is no separate track for AI and Open Science, as we believe AI will influence all conference topics, i.e. it is transversal. We encourage you to include AI wherever you see fit.

Contribution Types

There are four different types of contributions you can submit:

• Individual Presentations
• Panels
• Collaborative Workshops
• Posters

In the following, each contribution type is described in more detail:

Individual Presentations

The presentation should be 40 minutes with a maximum of 30 minutes of talk and at least 10 minutes time for questions and discussion. If you submit an individual presentation, your contribution will share a session with another individual presentation from the same or a similar track.

Panels

A panel session lasts 90 minutes and can have two or three speakers and at least 30 minutes of Q&A with the audience. The panel should include a moderated discussion among the panelists.

Collaborative Workshops

There will be slots for workshops of 180 minutes, with possibilities to do focused work on a specific topic. These slots are entirely committed to the conference theme of collaboration. Choose this contribution type if you want to work with a group of maximum 30 people on a tool, on guidelines, on a statement, or anything else.

Posters

The poster session will take place in person during the reception on Monday evening. Posters, preferably in format A0 will be displayed for networking and engagement opportunities. Additionally, posters will be published online after the conference through Zenodo.
