  Cornell University is a private Ivy League and statutory land-grant research
  university based in Ithaca, New York, ranked #16 in the QS World University
  Rankings 2025. Its public developer footprint is decentralized rather than
  served through a single API gateway: the Class Roster team publishes a
  documented Class Roster API for course and scheduling data, the Cornell
  University Library operates the eCommons digital repository on DSpace with
  REST and OAI-PMH access, and Cornell hosts arXiv with its long-standing public
  arXiv API. The student-led Cornell Open Data Initiative (CODI) additionally
  exposes campus map, transit, dining, and events datasets, though parts of that
  platform are archived or marked as likely outdated.

    description: >-
      eCommons is Cornell University Library's institutional repository, running
      on DSpace 7+. It exposes a public DSpace REST API for items, communities,
      collections, and bitstreams, and an OAI-PMH endpoint for metadata
      harvesting using Dublin Core. The library migrated to new DSpace
      infrastructure in January 2026.

    name: Cornell Open Data Initiative (CODI)
    description: >-
      CODI is a student-led effort to publish open Cornell data including campus
      map points of interest, transit (TCAT) schedules and stops, dining, and
      events. API documentation has been synced to SwaggerHub via the CODI
      repositories, but several CODI data repos are archived and the platform is
      described as undergoing a revamp with datasets that may be outdated.
