IIIF APIs for the DRS • The DRS Image Delivery Service (IDS) implements the Image API http: //ids. lib. harvard. edu/ids/iiif/5981214/0, 0, 1200/pct: 50/ full/native. jpg • Displays the image or image region that has been specified • A new LTS service implements the Presentation API • http: //iiif. lib. harvard. edu/manifests/drs: 5981093 • Returns a JSON manifest for a PDS object in the DRS • The DRS Page Delivery Service implements the Mirador open source viewer which in turn uses both APIs
