Abstract :
[en] At the University of Liège Library, ensuring interoperability between research and discovery systems is a central aspect of supporting open science and research workflows. This presentation examines the current state of integration between key platforms in the ULiège research ecosystem: the Alma library system and Primo discovery layer, the ORBi institutional repository for publications, and the ULiège Dataverse for research data. Particular attention is given to the role of persistent identifiers (such as DOIs, Handles, ORCID, and IdRef) and metadata standards (including Dublin Core, MARC, and OAI-PMH) in enabling connections across systems. The presentation outlines the ways in which metadata is shared and reused, the current limitations of cross-platform discovery, and the implications for researcher visibility and citation. Ongoing efforts to improve data quality, automate linking, and expand discoverability are discussed, including the potential integration of software outputs. By highlighting both achievements and unresolved challenges, this presentation aims to contribute to a broader reflection on metadata interoperability in academic institutions.
