description: >-
  National Yang Ming Chiao Tung University publishes no rate-limit table for any of its surfaces,
  and neither the OAuth documentation nor the terms of service mention throttling. The two
  OAI-PMH endpoints may throttle large harvests; both advertise gzip/deflate compression and the
  NYCU Dataverse robots.txt disallows all crawling, so harvest through the OAI-PMH protocol rather
  than by crawling the web UI. Corrected 2026-09-01 — the previous description named IIIF and
  library endpoints that were never measured on this institution.
notes: >-
  No published limit was found on any NYCU surface. Confirm per-service limits with each
  service; harvest responsibly. dataverse.lib.nycu.edu.tw/robots.txt is User-agent * / Disallow /.
