Understanding the impacts of Open Science (OS) and the extent to which they materialise requires a solid methodological framework, which is not yet fully established. The Cost-Benefit Analysis (CBA) framework for OS - developed (part of the PathOS project) - aims to provide a systematic and comprehensive approach to quantifying the impacts of OS. This framework goes beyond simply evaluating benefits; it incorporates associated costs and enables meaningful comparisons with scenarios in which OS is not implemented.

This presentation will illustrate key elements of this framework, focusing on the types of costs (e.g.,set-up and maintenance costs) and benefits (e.g.,costs saved) specifically related to open science, and details the methodology to quantify these elements within the context of a CBA. Real-world applications of this framework will be used to offer practical insights into its utility and effectiveness. In particular, the presentation will draw on the use of the CBA to assess the value of:

UniProt, a widely used and freely accessible open database for protein sequence and functional information.

RCAAP, a network of open institutional repositories involving multiple Portuguese research institutions.

This presentation will show how the CBA framework can support policy and funding decisions and demonstrate the value of OS practices in research infrastructures. It will also shed light on the challenges that may arise when applying this framework and offer recommendations for potential mitigation strategies and actions. These insights are intended to enhance the utility of the framework as a valuable tool for the future evaluation of OS resources.

This presentation delivers a critical policy assessment of national Open Science (OS) strategies and policies across selected EU Member States, examining their alignment with, and divergence from, supranational frameworks, particularly EOSC and broader EU digital agendas. Drawing on socio-epistemological theory and a critical analysis of policy and infrastructural dependencies within the EU, it explores how national approaches negotiate the balance between epistemic autonomy, institutional capacity, and compliance with common standards.
The assessment applies an evaluation framework, encompassing: the existence of national OS instruments (strategy, action plan, monitoring), thematic coverage (open access, open data, education, etc.), stakeholder engagement, legal enforceability, implementation mechanisms, degree of EOSC/EU alignment, incorporation of research assessment reform, evidence-informed policy development, and reliance on national strategic frameworks and development priorities. Countries are evaluated qualitatively, based on policy documents and data sourced from the EOSC Observatory and official national portals. The assessment framework also considers the SMART criteria.
Croatia is presented as an in-depth case study of a still-emerging policy ecosystem. The analysis includes the 2023 Draft National OS Plan. Complementing this, the presentation introduces original survey results on OS awareness and perceptions among Croatian researchers and students covering all major OS components conducted throughout 2024 and 2025 with the aim of producing a white paper to inform future policymaking.

Designing What Matters: Rethinking Open Science Monitoring Together
How should we measure and reward Open Science in ways that matter to researchers, institutions, and funders? In this 90-minute co-creation workshop, participants will build their own Open Science dashboard using real indicators from PathOS and GraspOS Horizon Projects. Working in groups, you’ll craft visual prototypes, debate what to measure and why, and explore how stories, not just scores, can drive meaningful change in research assessment. Join us to design smarter, fairer ways to track Open Science impact.

The RDA TIGER project has played a pivotal role in supporting Research Data Alliance (RDA) Working Groups (WGs) that align, harmonise and standardise Open Science developments and technologies globally. While the RDA is a global platform, one of RDA TIGER’s key selection criteria for supporting WGs and projects is their potential impact on solving European data challenges and promoting data sharing and Open Science, in alignment with the EOSC Strategic Research and Innovation Agenda (SRIA). The RDA TIGER project supports 23 WGs and has funded 9 projects, each with a tangible impact on the EOSC ecosystem and related challenges.  To articulate the value and impact of the RDA TIGER project on the European landscape and EOSC ecosystem, in early 2025, the project team embarked on a large-scale landscape analysis to map the impact of RDA WGs to EOSC. This presentation features an in-depth analysis and lessons learnt from this endeavour.  

Specifically, we will: 

Introduce the landscape report as a tool and resource for European data professionals, EOSC users, researchers, and policymakers enabling them to navigate the wealth of RDA outputs that address key challenges in the region.
Present preliminary results and lessons arising from the mapping of the RDA WGs and their direct contributions to the SRIA priorities and challenges.
Highlight forward-looking recommendations coming out of the report.

By illustrating the tangible outcomes of RDA TIGER’s support, this presentation provides key insights into how collaborative, international research data initiatives can drive meaningful change in Europe and beyond.

Telling the Story of Open Science Impact: From Indicators to Action
As Open Science policies gain traction, so does the need to show what impact they truly have. This hands-on workshop introduces the Open Science Indicator Handbook from the PathOS Horizon Europe project, your guide to designing meaningful, evidence-based indicators. Join peers in crafting real-world narratives around indicators that matter. Explore how tracking open practices can shape behavior, influence policy, and advance equity and societal benefit. From numbers to stories, help turn impact into insight.

International Relations are established for various purposes; however, the nature of this Open Science Fair 2025 “Fusing Forces – Accelerating Open Science through Collaboration” invites us to address the relationships that exist around Cooperation, specifically new trends.
To this end, we will review briefly what has characterized these ties for years, and then we will suggest an alternative in detail, illustrated with a successful example that is currently in operation.
Traditionally, International Relations are defined as diplomacy, understood as the relationship established by nations or nation-states as a whole, such as a federal or central government, whether bilateral, one-on-one, or multilateral, between more than two countries. However, starting in the 1980s, a series of non-traditional manifestations of what has come to be known as paradiplomacy began to emerge. New actors with common expectations belonging to different systems and degree of decentralization have been working cooperatively without the intervention of central governments. Our example involves two different organizations: a Mexican research center and OpenAIRE, as subnational and supranational actors respectively.

A comparative table will show how the most representative features of paradiplomacy and its application in the creation of North American Studies (NAS). NAS is an ongoing collaborative project that transcends borders and contributes to strengthening one of the Open Science infrastructures, within the framework of the Open Science UNESCO recommendation and the FAIR principles. Scientific paradiplomacy is imperative in times of uncertainty and paradigm shift in international relations.

The presentation explores open science policy development in Finland in the context of stakeholder engagement and the creation of the first national policy recommendation for citizen science with focus on measuring impact and community engagement.

The presentation is based on two 2025 studies. First study is established on the shift of responsibility for coordinating open science in Finland from the Ministry of Education and Culture to the Finnish research community, specifically the Federation of Finnish Learned Societies (TSV). We examined documents from the TSV citizen science working group, including meeting notes, survey results, and the final policy paper, to understand how stakeholder participation influenced the policy-making process.

The second study examines the impact that the recommendation had on the stakeholders. We examined survey results, and the performance of citizen science indicators based on the recommendation from the national open science and research monitoring results from 2024 to explore the impact of the recommendation.

The results show that involving stakeholders helped shape policy recommendations, especially in improving institutional support, guidelines, and funding visibility for citizen science. However, challenges like uneven awareness and engagement among stakeholders could limit the effectiveness of participatory approaches. By placing these findings within the context of participatory policymaking and stakeholder theory, the presentation provides insights into how inclusive policy design works and how participatory governance and science policy development can be integrated into institutional frameworks to drive change.

The emergence of a digitally enabled Open Science has coincided with the vast growth of high education in the Global South, leading to a vast expansion of research and publishing activity, as attested to, for example, by the 55,000 journals (almost entirely open, without fees for readers or authors) using the journal publishing platform Open Journal Systems (OJS) launched in 2002. The rate and scale of this expansion of research may well lead to a great many missed opportunities in utilizing relevant research findings, vital to the advancement of science, whether through shortfalls in indexing or mistrust of unfamiliar sources. On the principle that we not only to open science but must find ways of supporting researcher and public use of this open science activity, I present an experiment in developing a credible standardized label for each research publication that precisely summarizes its adherence to scholarly publishing standards in ways designed to inform readers about those standards. The resulting “Publication Facts Label,” lists eleven data points, from number of reviewers to days to publication, all securely drawn from the journal publishing platform. Intended for industry-wide use, it is currently being tested with journals using OJS, with this presentation reviewing the label’s design for researchers and public, its integrity and trust features, the implementation plan, as well, as its review by Nature readers, open access publishers, school students, and others, while offering attendees ways of seeing the label in action and, if so inclined, supporting its adoption.
