Johns Hopkins Research Portal (Elsevier Pure tenancy)
The Johns Hopkins research information portal at pure.johnshopkins.edu, which CNAMEs to jhu.elsevierpure.com. This is an Elsevier Pure tenancy: the researcher profiles, publications and organizational data are Johns Hopkins', the platform and every API contract on it are Elsevier's. Recorded as a TENANT relationship, which is a real institutional fact worth keeping. Pure's own web services (/ws/rest, /ws/api, /ws/oai) all answer 401 — deployed but closed to the public. No Elsevier contract is saved under this institution.
