Open Data Day: Discover HaDEA-managed projects advancing European data spaces – INSIGHT EU MONITORING

Brussels, 16 March 2026
The Open Data Day marks the role of open data and data sharing in the development of society and the use of open data around the world. By implementing the European Data Strategy, the EU sets out the vision of creating a single market for data where it can flow freely within the EU and across sectors. One pillar of this strategy is the Common European Data Spaces.
These data spaces lay out specific design principles, featuring interoperability and interconnection within a single market for data. The Data Union Strategy, adopted in November 2025, made proposals to further expand the data spaces.
The Digital Europe Programme has been the backbone instrument financing the roll-out of the Common European Data Spaces, funding specific data space initiatives to address the needs of particular sectors. The implementation of some data spaces is managed by HaDEA. Let’s take a closer look at some examples.
The European Tourism Data Space is currently being developed through the implementation of the Deploytour project by a consortium of 43 partners from over 13 different countries. This three-year project adopts common open standards and protocols to maximise compatibility both within the tourism sector and with other data spaces, while ensuring data sovereignty. This open-standard approach also reflects the principle of interoperability, promoting the use of open data formats and interfaces.
The project deploys five use-case pilots in five European countries to demonstrate the tangible advantages and viability of the Data Space, as well as its impact on the European tourism sector. The pilots are centred on increasing sustainability, optimising processes and making the sector more resilient through digitalisation and data-driven solutions.
The Common Data Space for Cultural Heritage is led by the Europeana Foundation in collaboration with a consortium of 18 partners from nine EU countries. The Data Space enables cultural heritage institutions and citizens to access, engage with and reuse cultural heritage data. The Data Space steadily increases the amount of high-quality, usable and accessible data available, helping to diversify the data offer. Interoperability is one of the key features of the Data Space and is achieved through open-source solutions and the Europeana Data Model. Several projects, such as 5DCulture, Eureka3D, and RCtoDC, have aggregated data and equipped the Data Space with new applications and capacity-building training.
A key role in the deployment of the common, secure and trusted European Data Space for Skills is played by the DS4SKILLS project, which connects 22 key stakeholders across Europe to enhance digital skills, improve employment opportunities and provide practical benefits to both organisations and individuals in the digital age. Eight sustainable use cases focus on key challenges such as lifelong learning, upskilling and employee retention, demonstrating the practical benefits of the European Skills Data Space.
Another project significantly contributing to scaling up the deployment and use of the Data Space for Manufacturing is CircPlastX. Its objective is to reach a critical mass of manufacturing industries sharing industrial data and improving company operations and value chains among providers. The project aims to unlock the value of data sharing across the plastics value chain to accelerate circular economy practices, support regulatory compliance (for example: Digital Product Passports, the Corporate Sustainability Reporting Directive and REACH), enable trusted and interoperable data exchange, promote reuse, recycling and design for circularity, and foster innovation and new data-driven services. Data between designers, producers and recyclers in this sector is currently rarely shared, and the project aims to change that.
In the health sector, the European Health Data Space (EHDS) Regulation, entered into force on 26 March 2025, aims to establish a common framework for the use and exchange of electronic health data across the EU. The EHDS will empower individuals to access, control and share their electronic health data across borders for healthcare delivery (primary use), enable the secure and trustworthy reuse of health data for research, innovation, policy-making and regulatory activities (secondary use), and foster a single market for electronic health record (EHR) systems supporting both primary and secondary use.
In general, data spaces will facilitate secure data pooling and data sharing by establishing appropriate governance structures and providing mechanisms for entering into data-sharing agreements. This helps address key challenges such as building trust among participants and overcoming interoperability issues. By making data more accessible and usable, data spaces are expected to foster dynamic ecosystems in which new products, services and innovative data-driven solutions can be developed.
The Digital Europe Programme (DEP) aims to build the EU’s strategic digital capacities and facilitate the wide deployment of digital technologies. With an overall budget of €8.1 billion, of which €0.8 billion is managed by HaDEA, the programme supports investments in the following sectors:
HaDEA manages projects under Artificial Intelligence, Advanced Digital Skills and Best Use of Digital Capacities and Interoperability.
