HAL

HAL is the French national open repository for scholarly publications, open to researchers from all disciplines and countries. It hosts over 1.5 million full-text documents, 70% of which are in English, and supports more than 150 institutional portals from French universities and other research organisations. It is a general-purpose repository and can also provide deposit and specific services for software thanks to a collaboration with Software Heritage..

All submissions undergo a verification process prior to publication, and metadata are curated and aligned with international standards. In addition to bibliographic data, HAL provides rich contextual metadata—such as affiliations, funding, and project information—and supports links to related outputs like datasets and software. HAL is CoreTrustSeal certified and acknowledged by the European Research Council as a trusted repository.

• Enhance the discoverability of HAL metadata and its richness
• Improve the FAIRness of HAL metadata
• Ensure the pairing of publications in HAL with datasets

The expected results of the project include enhanced discoverability of HAL metadata along with the development of a knowledge graph that links publications with related datasets, facilitating more integrated access to research outputs and promoting greater transparency and reproducibility in science.
