Thank you to everyone who supported the project and participated in our final event!

After three years of collaboration, Project MareGraph has been successfully completed. To wrap up the project, the consortium is hosting a public webinar to present and demonstrate its key outcomes from a researcher’s perspective.

MareGraph is about connecting important marine databases (EurOBIS, WoRMS, MarineRegions) into one smart, interlinked system so computers can ‘understand’ how species, places, and observations in the ocean relate to each other. By doing this, it becomes much easier for scientists, policymakers, and even AI tools to discover, combine, and reuse marine knowledge to better understand and protect our seas.

During the webinar, we’ll run a live demo highlighting the project’s main results: new dataset formats and services, open-source tools and code libraries, reusable ontologies, and an international semantics governance workflow.

• 👩‍🔬👨‍💻 For who? Marine researchers, data managers, infrastructure developers, and anyone interested in linked data and knowledge graphs with EurOBIS, WoRMS, and Marine Regions.

• 👉 Join us to see what MareGraph delivers — and how its results can be reused beyond the project.

• When: March 3rd, 14:00 - 15:30 (1 hour demo and explanation + 30 mins Q&A)

After three years of collaboration and innovation, Project MareGraph has officially come to an end. The project concluded in December 2025, having successfully delivered 15 deliverables and reached 7 key milestones. It has been a pleasure working within such a small yet highly impactful consortium.

Final Deliverables Published

We’re happy to share that the final deliverables are now publicly available on Zenodo:

• D4.4 – LDES-based Web Indexes

• D5.4 – EurOBIS/LOD

These publications represent the culmination of our collective efforts and provide concrete outcomes for the community to build upon.

End-of-Project Webinar

Curious to see MareGraph’s results in action? Join us for our end-of-project public webinar on March 3rd (14:00–15:30).

During the webinar, we will:

• Showcase how to use the Linked Open Data (LOD)
• Present practical use cases
• Offer dedicated time for questions with our work package leaders

Stay tuned—we look forward to sharing and celebrating the results with you! If you would like to join please mail info@maregraph.eu

Our multi-channel dissemination strategy includes a dedicated website, active social media presence, open-source GitHub repositories, and a public data catalog compliant with European standards. These efforts have helped maximize the project’s visibility and engagement.

Looking ahead, MareGraph will release its integrated Knowledge Graph by the project’s end, combining key marine biodiversity data to support future research and collaboration.

Building on earlier work, this release introduces critical updates, a brand-new Marine Observations ontology tailored to biodiversity data, and robust SHACL shapes for validation—ensuring both flexibility and precision. Altogether, the MAREGRAPH ontology suite now includes five domain-specific modules and a top-level ontology grounded in foundational frameworks like DOLCE.

This milestone marks a major leap toward more open, connected, and reusable marine data, with all resources publicly available and actively maintained at our GitHub repository.

Today, overlooking the Basilica di Santa Maria in Montesanto, the MareGraph consortium gathers in Italy for our second-to-last General Assembly, hosted by our partners at CNR - Istituto di Scienze e Tecnologie della Cognizione. 🌊

Over two productive days of planning and workshops, we’ve laid out the roadmap for the final six months of our 3-year project. Highlights ahead include:

• The release of MareGraph’s final ontology design and development – coming next month
• The publication of EurOBIS as Linked Open Data – expected this December

We’re proud of the milestones ahead and grateful for the collaboration driving this work forward.

The Public Sector Tech Watch (PSTW) observatory launched in 2024 the ‘Best Cases Award’. The aim was to spotlight solutions using emerging technologies (Artificial Intelligence, Blockchain, etc.) in public administrations at all levels to enhance public services for citizens (G2C) or to improve their internal processes (G2G). On the one hand, the award aimed to generate a virtuous mechanism for sharing the best experiences on the use of emerging technologies in the public sector; and on the other, to give visibility to the most innovative public administrations in Europe.

This exclusive webinar on Nov 19, 2024 brought together four pioneering EU-funded projects — Open Maps for Europe 2 (OME2), MareGraph, RODEO, and BeOpen. This event showcased their collaborative efforts to revolutionise the landscape of High Value Datasets (HVDs).

Agenda and presentations:

• Welcome – Angela Baker
• Introduction - Antonio Filograna
• Keynote speech “The value of HVD in the future EU economy” – European Commission Project Officers Stefano Bertolo, Johan Bodenkamp, Riku Leppanen and Daniele Pagliuca
• Brief presentation of the 4 Cluster projects – Project Managers Antonio Filograna (BeOpen), Victoria Persson (OME2), Lennert Tyberghein (MareGraph), Timo Kyntaja (RODEO)
• Panel discussion / Q&A through Slido
• Conclusion - Antonio Filograna

Advancing Semantic Assets for Organizational Interoperability: Insights from Deliverable D2.2Permalink Building upon the foundation set in Deliverable D2.1, the latest Deliverable D2.2 takes the next step forward in refining the process and methodology for creating semantic assets that can be effectively utilized across different Member States. The importance of establishing a clear process and methodology for organizational interoperability cannot be overstated.

Organizational interoperability ensures seamless communication, smooth data exchange, and efficient collaboration between various departments, systems, and organizations. By implementing a standardized approach, organizations can improve their operational efficiency, reduce the likelihood of errors, and make more informed, data-driven decisions. This not only optimizes internal workflows but also enhances the ability to collaborate across borders, fostering a more integrated and effective environment for all stakeholders involved.

Today, VLIZ presented the implementation plan for the EurOBIS Linked Open Data (LOD). The report outlines the expected features and service interface points for the new components to be developed. It takes into account the current state of the EurOBIS database system and workflow, alongside the overall planned architecture detailed in the D4.1 Whitepaper.

The goal is to serve as both a development guide and a concise description of the new services that the LOD and LDES publications of EurOBIS will offer.
