We [have] published more than 30,000 images from the Getty Museum’s collection on Getty.edu using IIIF. You can see and click on the red-and-blue logo underneath the main image of any of the Museum collections, … to explore our content through any IIIF-compatible viewer.

We’re happy to join another IIIF partner, the Yale Center for British Art, which is also releasing images as IIIF today—you can read their announcement here and browse their collection here.

About IIIF

IIIF (pronounced “triple eye eff”) is the acronym for the International Image Interoperability Framework. This framework comes from a broad community of primarily cultural heritage organizations that are working together to come to practical consensus around the publishing of digital images. By adopting the framework, the public as well as scholars can bring together images from any of the participating organizations for comparison, manipulation, and annotation in a single user interface. This community has agreed upon, published, and implemented two major specifications. Representing the Getty in this community, and working toward implementation of IIIF here, has been one of my major roles since joining the Getty as semantic architect.

The images now available via IIIF are from the Open Content Program. These were selected as the first tranche of content, as the rights have already been cleared to make them openly available. Any new images added to the Open Content set will automatically be available via IIIF, and images from Getty Research Institute collections are expected to be available before the end of the year.

Implementation at the Getty

“The Getty Museum has published an implementation of both the Image and Presentation APIs on its online collection. The Image API gives access to the images’ pixels, enabling the smooth and deep zoom you’ll experience in the Mirador client, along with technical information about the image such as its dimensions and available formats. The Presentation API gives the rest of the information you’ll see—the title of the object and all of its metadata, rights information, and, if there is more than one image, the order in which to display them.” *

“The viewer that appears when you click the IIIF icon is called Mirador. We chose Mirador because it allows comparison of multiple objects—a key scholarly use case—and will support annotation of the images when we add the infrastructure to manage the annotations created.

To do a side-by-side comparison:

  1. Select an artwork from the Getty Museum online collection that has a IIIF icon (just below the image and to the right).
  2. Click the IIIF icon to open the Mirador viewer.
  3. Select “Change Layout” at the top right to add one or more slots where you’d like additional artwork images to display.
  4. Select another artwork (with an IIIF icon) that you’d like to compare. Go to the webpage for this object and drag the IIIF icon from that browser tab or window into the new slot you’ve just created. The two images will now appear side by side.”

This will work to compare objects within the Getty Museum collection, but also objects held by other institutions that enable IIIF functionality, such as the Yale Center for British Art. For example, you might want to compare Turner’s depiction of stormy seas in the Getty’s Van Tromp Going about to Please His Masters and with the Yale Center for British Art’s Stormy Sea Breaking on a Shore.”

* “The implementation was carried out primarily by Daniel Sissman, the Museum’s software architect, over the course of only two afternoons! I was mostly there to answer questions and provide advice from other implementation experience. The work revolved around extending the existing capabilities of the Digital Object Repository (DOR) to produce a different JSON syntax for the descriptions, and figuring out how to translate between IIIF requests and the existing image tiles used in the current collections web interface. The DOR is an access layer on top of our collection management system, TMS, to provide the content in more usable, read-only formats.” (The Getty).
