What is IdRef?

IdRef (Identifiants et Référentiels pour l’Enseignement supérieur et la Recherche) is a web application developed and maintained by ABES. IdRef allows users and third-party applications to query, consult, create and enrich authorities.”

IdRef is used in many databases (, Persée, HAL…), thus promoting interoperability between platforms.
