Trinity College Dublin site OpenSearch description
An OpenSearch 1.1 description document served as application/xml from Trinity's own domain and explicitly authored by Trinity — the document's own Developer element reads "Trinity College Dublin, Digital and Web team". Small, but it is a machine-readable contract the institution wrote and still serves. Note that its Url template still points at the retired search.tcd.ie appliance, which now 301s to www.tcd.ie/search/q/.
