PKU Open Research Data Platform (Dataverse REST API)
Dataverse-based research data repository operated by the PKU Library across social science, health, bioinformatics and NLP collections. Verified live by this catalog on 2026-06-03 (183 dataverses, 485 datasets). During the 2026-08-19 pass the host completed TLS and answered a 301 on port 80 but never returned an HTTPS response, across seven attempts; recorded as unreadable from our vantage point rather than removed, since nothing observed proves the surface is gone.
