Ireland as an Open Data Trendsetter in Europe: Insights from the 2025 Open Data Maturity Report

A closer look at Ireland’s performance across policy, portal, quality and impact.

Ireland has once again been recognised as a European leader in open data, achieving a 96% overall maturity score in the 2025 Open Data Maturity (ODM) assessment, published by the European Commission via data.europa.eu .

The annual assessment evaluates how countries across Europe are progressing in making public sector information openly available and supporting its reuse. In 2025, Ireland remains firmly among Europe’s “trendsetter” countries, reflecting a sustained and coordinated approach to open data policy, delivery and governance.

Ireland’s 96% overall score places it well above the EU average and confirms its continued position in the top tier of participating countries.

The assessment measures open data maturity across four equally weighted dimensions: policy, portal, quality and impact; each contributing 25% to the overall score. Ireland continues to perform strongly across all four, with particularly high scores for policy, portal and impact.

Ireland achieved a 99.2% score in the policy dimension, confirming the strength and maturity of its open data governance framework.

The report highlights Ireland’s ongoing implementation of the National Open Data Strategy 2023–2027, which has been actively promoted across public sector networks and events. Strong processes are in place to ensure policies are implemented in practice, with the majority of public bodies engaged in open data initiatives.

Ireland also continues to support national coordination and consistency, reinforcing open data as a core element of digital governance across the public service.

Highlight from Ireland – Irish technical services framework

To help public bodies comply with the Open Data Directive, Ireland established the technical services framework, a streamlined mechanism for accessing specialised open data services. This framework acts as a pool of pre-qualified service providers for open data and data management, ensuring that public sector bodies can quickly obtain expert support without lengthy procurement processes.

Through a simple request form, authorities can access services such as:

• data management – audits, cataloguing, preparation, publication, maintenance and maturity assessment;
• hosted open data platform solutions – _ready-to-use infrastructure for publishing and managing datasets;
• consultancy services – expert guidance on open data and data management practices.

By centralising technical expertise and simplifying service delivery, the framework accelerates compliance and reduces the burden on local and regional bodies, making open data implementation more efficient and sustainable.

Ireland’s national open data portal scored 97.8% in the portal dimension, reflecting a year-on-year improvement and the continued expansion of the platform.

At the time of the assessment, the portal featured:

• Over 21,000 datasets
• Contributions from 143 public sector bodies
• 82% of datasets available via APIs
• 21 automated data harvesters
• Between 120 and 500 new datasets added each month

Since the assessment was completed, additional datasets, features and technical improvements have been introduced, further strengthening the portal. One example is the introduction of datAdore Insights, a data visualisation feature that enables publishers to turn raw datasets into interactive dashboards and data stories, making data easier to understand, explore and share. Visualisations can be created and published directly within the portal, supporting both discovery and reuse.

These enhancements are not reflected in the 2025 scores but demonstrate the ongoing, incremental nature of Ireland’s open data programme, rather than a one-off or point-in-time exercise.

Highlight from Ireland – enhancing reach through strategic promotion and engagement

Ireland has adopted a multichannel approach to increase visibility and engagement with its national open data portal. By combining targeted outreach, strategic partnerships and user-focused communication, the portal team has successfully broadened its audience and encouraged greater data use.

Key initiatives include the following.

• Newsletter and network amplification. The portal’s newsletter is widely –  not only to subscribers but also through key networks such as open data liaison officers, the advisory group and the governance board.
• Training and public sector collaboration. Open data training is shared via public sector learning and development teams, helping to build awareness and capacity across government bodies.
• Social media and event outreach. The team actively promotes the portal on platforms like X and shares QR codes during conferences and university events, such as Love Data Week, to engage students, researchers and the wider public.
• User-focused platform and strategy. Ireland’s second national open data emphasises user engagement, while the portal itself offers intuitive navigation, topic-based categorisation and regular updates to support discovery and usability.
• Community building and support. Through the Open Data Engagement Fund, workshops and direct support to data publishers, Ireland fosters a vibrant open data ecosystem that encourages both data publication and reuse.

Ireland recorded a 90.5% score in the quality dimension, making it the lowest-scoring of the four dimensions, while still reflecting a strong level of maturity and a year-on-year improvement.

The assessment highlights positive developments in:

• DCAT-AP compliance
• Metadata currency and completeness
• Monitoring and quality assurance processes
• Deployment quality and linked data

The Ireland country factsheet also highlights the publication of Companies Registration Office datasets, including historical financial statements, as a key milestone. This supports Ireland’s High-Value Dataset (HVD) obligations under the Open Data Directive, with the data made available in the required formats and through designated channels to support transparency and reuse across sectors.

At the same time, DCAT-AP compliance is identified as an area slightly below the EU average at the time of assessment. It is important to note that additional DCAT-AP improvements were implemented during 2025 but after the ODM data collection period had concluded, meaning these changes are not yet reflected in Ireland’s 2025 score.

These more recent upgrades align closely with European interoperability requirements and form part of Ireland’s ongoing, continuous approach to data quality improvement, which is expected to be reflected in future Open Data Maturity assessments.

Ireland scored 96.6% in the impact dimension, reflecting mature practices for defining, monitoring and assessing open data reuse.

The report confirms that Ireland:

• Has a national definition of open data reuse
• Monitors reuse levels
• Applies a methodology to assess impact

This structured approach supports a growing focus on demonstrating the real-world value of open data across government, society, the environment and the economy.

While the 2025 Open Data Maturity Report confirms Ireland’s strong position in Europe, it also underlines an important reality: open data maturity is not static.

Looking ahead, Ireland’s open data programme continues to mature in a consistent and sustainable way. Strong policy foundations, a highly scalable national portal, improving data quality practices and a clear focus on impact together support continued progress across Ireland’s open data ecosystem.

As European requirements continue to evolve — particularly around high-value datasets, APIs and interoperability — Ireland is well positioned to build on this momentum and maintain its role as a leader in open data and public sector data reuse.
