Cornell University

aid: cornell
name: Cornell University
description: '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  campus map, transit, dining, and events datasets, though parts of that platform are archived or marked as likely outdated.'
