6. IIIF APIs for the DRS The DRS Image Delivery Service (IDS) implements the Image API http://ids.lib.harvard.edu/ids/iiif/5981214/0,0,1200,1200/pct:50/ full/native.jpg http://ids.lib.harvard.edu/ids/iiif/5981214/0,0,1200,1200/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
