The Harvard Art Museums make their collections interoperable through several IIIF compatible services and tools. The museum’s services build on the Harvard libraries implementation of the IIIF image API on the Harvard Digital Repository Service (DRS). The Harvard Art Museums exposes collection image URLs and IIIF URIs to the DRS services as part of the dataset accessible through the museum’s API (see http://www.harvardartmuseums.org/collections/api). In conjunction with exposing IIIF compatible image URIs the museums run a presentation service that exposes IIIF compatible manifests and collections. The museums manifest server is based on software that was developed for HarvardX.
The museums also provide access to more than 350,000 annotations. They are exposed as annotations lists in manifests and directly through the museums API.
