NYCU Dataverse OAI-PMH Endpoint

Anonymous OAI-PMH 2.0 metadata-harvesting endpoint over the NYCU Dataverse research-data repository ("NYCU Dataverse Dataverse OAI Archive"). Verified with verb=Identify on 2026-09-01. Serves Datacite, oai_dc, oai_ddi, oai_datacite and dataverse_json metadata formats, and publishes named sets including all_nycu ("All NYCU datasets"). The baseURL below is the OAI-PMH protocol base URL; per the protocol it requires a verb, and a bare GET on it returns 500 rather than a 400 badVerb error.

aid: nycu:dataverse-oai-pmh
name: NYCU Dataverse OAI-PMH Endpoint
x-operator: institution
x-operator-evidence: dataverse.lib.nycu.edu.tw resolves to 140.113.39.17, inside NYCU's own allocation,
  and the OAI-PMH Identify response names NYCU as the repository with adminEmail cyliu+libdv@lib.nycu.edu.tw.
  OAI-PMH is an open protocol rather than a vendor contract, so the endpoint is the institution's even
  though the software serving it is the Dataverse Project's.
