  title: University of Southampton Open Data Service (Linked Data)…
  version: '1.0'
  x-generated: '2026-08-30'
  x-method: derived
  x-source: Derived from live probes of data.southampton.ac.uk and id.southampton.ac.uk on 2026-08-30. URI dereferencing, format-extension content negotiation and dataset dump retrieval were each exercised against the running service. Captured responses are held in examples/open-data-dcat-catalog.ttl, examples/open-data-building-94A.ttl and examples/open-data-building-94A.rdf. The University publishes no OpenAPI description of this service; this document is API Evangelist's, not the institution's.
  x-operator: institution
  x-operator-evidence: 'data.southampton.ac.uk is a CNAME to sni-vserver-02.soton.ac.uk (152.78.118.88) and id.southampton.ac.uk to websites-ecs.soton.ac.uk (152.78.118.28) — both inside the University''s own JANET address space and its own registrable domain. The catalogue''s own DCAT record names dcterms:publisher <http://id.southampton.ac.uk/>, typed as an aiiso:Institution labelled "University of Southampton". No vendor platform is involved: the FAQ states the service is built on Sesame, Grinder, rapper, Graphite and sparqllib, with Grinder written for this project at Southampton.'
  description: 'The University of Southampton Open Data Service, one of the longest-running institutional linked open data programmes in higher education and a genuine outlier in this cohort: it is institution-built, institution-hosted and institution-maintained, with no vendor contract behind it.'
