University of Vienna

aid: university-of-vienna
name: University of Vienna
description: 'The University of Vienna (Universität Wien), founded in 1365, is Austria''s largest university and ranks #78
  in the QS World University Rankings 2025. Its public, programmatically accessible footprint centers on research and scholarly
  infrastructure rather than a unified developer portal: PHAIDRA, the university''s institutional repository, exposes a documented
  REST(ish) API and an OAI-PMH metadata harvesting endpoint, and the institution''s structured data is also published through
  the pan-European HEI API. Course, library discovery (u:find / u:search) and student-information systems are public web services
  but do not publish open developer documentation. No central, branded API developer portal or official GitHub organization
  was confirmed.'
