Oxford Canvas VLE (Instructure tenancy)
Oxford's virtual learning environment, replacing the retired WebLearn Sakai service. The Canvas LMS REST API and Canvas's LTI and Caliper conformance belong to Instructure. The Canvas REST API is live under Oxford's hostname and returns 401 unauthenticated, and Instructure's own API reference is served at canvas.ox.ac.uk/doc/api/ — an Oxford host serving a vendor's contract, which is the tenant case in miniature. Recorded as a relationship precisely so that Instructure's LTI certification is never counted as an Oxford domain-standard conformance — see the not-claimed section of conformance/university-of-oxford-domain-standards.yml.
