Dartmouth Dataverse
Dartmouth's research-data repository, a Dataverse 6.11 deployment on Dartmouth's own host. The native Dataverse API answers unauthenticated — /api/info/version returns 200 with the running version — but the contract is the Dataverse project's, shipped identically by every Dataverse installation, so no generic Dataverse specification is saved under Dartmouth. The deployment's OAI-PMH path is present and broken: /oai?verb=Identify returns a Payara 503 error page rather than an OAI-PMH document.
