As we usher in 2025, we're taking a minute to reflect on the remarkable progress of the OpenAIRE Graph over the past year. 2024 was truly an extraordinary year, marked by significant achievements and milestones that elevated the OpenAIRE Graph to new heights. We look forward to building on this success and continuing our journey of innovation and collaboration in the year ahead!

Sustainable Path

• The European Commission adopted the Graph as the authoritative source of information for the resource catalogue of the EOSC EU Node, launched in 2024;
• The Irish Research eLibrary (IReL) funded by the National Open Research Forum (NORF) chose the Graph as the input data for monitoring national scientific production via the National Open Access Monitor Ireland;
• SURF and UKB have also chosen the Graph and an OpenAIRE CONNECT gateway to offer the Netherlands a national portal for discovery and monitoring of Open Science production;
• The Graph contributed to scholarly communication innovation on FAIRness, interoperability, and Open Science indicators via the European projects FAIRCORE4EOSC, EOSC Track, SciLake, GraspOS, PathOS, EVERSE, OSTrails, and CRAFT-OA.

Data spotlight!

In 2024, 248 new data sources were registered to OpenAIRE PROVIDE by providers, reaching the impressive record of 2209 endpoints directly aggregated data/software repositories, thematic/institutional aggregators, and institutional/thematic/catch-all repositories.

• Research product records (after deduplication) reached ~193Mi publications, 73.5Mi datasets, ~600K software (~285K inferred by mining), plus 24Mi other kinds of products;
• Scholexplorer, the Graph’a citation index reached ~2.1Bi publication-publication (bi-lateral) links (21Mi inferred by mining), ~1.74Mi publication-dataset links (165K inferred by mining), ~58K publication-software links (7K inferred by mining).

Innovation spotlight!

• Boosting of the Graph web crawling infrastructure, allowing for ~80,000 PDF downloads per day, and renewal of bilateral agreements with publishers, including Elsevier, Wiley, ACM, and Springer Nature, bringing today ~63Mi full-texts to our mining infrastructure;
• Renovated and improved methods to identify ORCID ID references and ROR.org ID references in metadata and affiliation strings;
• Improved methods to derive and assign to metadata records a 3-level hierarchy taxonomy Fields of Science (FoS) classification and United Nations’ Sustainable Development Goals (SDG) indicators.

International collaborations!

Expanding global partnerships to improve quality and interoperability with the OpenAIRE Graph and advance Open Science scholarly communication at the global level.

• The Graph has become a provider of citation links to OpenCitations.net and is working closely with DataCite to transfer publication-data citations to the Data Citation Corpus;
• Renewed collaboration with EBSCO Information Services to integrate OpenAIRE Graph metadata into the EBSCO Discovery Service, improving global access to open scholarly records.
• Renewed partnership with Latin America’s La Referencia to strengthen Open Access initiatives across Latin American countries.
• Partnership with the National Science Library of the Chinese Academy of Sciences (NSLC), to promote Open Science and expand the OpenAIRE Graph in China.
• The National Institute of Informatics in Japan to enhance research infrastructure, data sharing, and policy alignment through a new Memorandum of Understanding.
• SciMago, OCLC (Online Computer Library Center), and ETH Zurich (Swiss Federal Institute of Technology) to evaluate and enhance the quality and coverage of the OpenAIRE Graph.

As we celebrate these milestones, we continue to look forward to 2025 and the developments it will bring. Notably, how researcher profiles will be further enhanced with the creation of person entities in the Graph.
