description: >-
  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.
