Ex Libris Alma / Primo VE — Princeton tenancy (01PRI_INST)
Princeton's library management and discovery layer runs on Ex Libris, with institution code 01PRI_INST: Alma at na05.alma.exlibrisgroup.com and a Primo VE instance at princeton.primo.exlibrisgroup.com. Both returned 200. The data is Princeton's — its holdings, its patrons, its link resolver targets, which surface in Allsearch results as resource_url values — but the API contract belongs to Ex Libris and is scored against Ex Libris, not Princeton. Recorded as a relationship because it is a real institutional fact and because Princeton's own bibdata service is built on top of it. No vendor spec is saved under this slug.
