École Normale Supérieure de Lyon

École Normale Supérieure de Lyon (ENS de Lyon) is a French public research and higher-education institution in Lyon, ranked #187 in the QS World University Rankings 2025. Its primary public, machine-readable developer footprint is its open-access institutional repository, HAL-ENS-LYON (ens-lyon.hal.science), which is part of the national HAL (Hyper Articles en Ligne) open archive. That platform exposes the publication metadata of ENS de Lyon through HAL's shared, well-documented APIs — an OAI-PMH endpoint scoped to the ens-lyon collection plus HAL's Search, Reference, and SWORD deposit APIs hosted at api.archives-ouvertes.fr. ENS de Lyon does not publish its own dedicated, branded developer portal; the institutional GitHub organization exists but currently has no public repositories.
