Unlocking Author-Affiliation Metadata for All of arXiv

The COMET team is pleased to share results from an exciting line of work we have recently completed, focused on unlocking author-affiliation metadata from preprints. With this approach, we have for the first time produced open author-affiliation metadata for the full arXiv corpus as of December 2025, enabling community use and allowing for direct improvements to persistent identifier metadata.

Participant Perspectives |  European Molecular Biology Laboratory (EMBL)

EMBL-EBI Perspective. ‘At European Molecular Biology Laboratory (EMBL), we see a clear alignment between our metadata initiatives and the goals of COMET (the Collaborative Metadata Enrichment Taskforce). COMET calls on institutions, repositories, and service providers to work together in enriching metadata in ways that are open, trusted, and scalable. Our internal initiative, ENRICH (Enhancing Open Infrastructure with Research Information and Curated High-Quality Metadata), is direct aligned to this call. What follows is a deeper look into the motivations behind our work and how EMBL’s effort supports and extends the COMET model.’
