Columbia University

Columbia Academic Commons

Columbia University's institutional research repository, holding the scholarly output, theses and research data of the university. Unusually for this cohort it is NOT a vendor tenancy: it runs on Hyrax/Blacklight — open-source repository software the Libraries help maintain — on Columbia's own host and hardware, with Columbia's own DOIs. The repository is therefore institution-operated in full. It could not be verified on this run: every request, including the OAI-PMH path and including requests presenting full browser headers, returns an Anubis proof-of-work interstitial with HTTP 200 and a bot-check body. No contract, schema or OAI Identify response is claimed for it, and no scored pointer is emitted to the host, because an Anubis-challenged host is indistinguishable from a soft-404 to an automated prober.
