Mirador Image Viewer

Spring 2023, we integrated the Mirador Image viewer into the Catalog. It will display images from IIIF Manifests. These are currently all located in our CONTENTdm, but could come from any source.

Sample record: https://catalog.libraries.psu.edu/catalog/2025781

URLs in Records

URLs should point directly to the manifest. Best practice is to will mint ARKs for these using the ii3 shoulder so they can be updated after migrations, but a raw URL ending in .json will work.

If there are multiple manifest URLs in the record, they will display in a tiled fashion in the viewer.

Syntax

IIIF manifest URLs should be entered using the following syntax and label. Going forward we may update the logic to look for either the subfield y text OR the ARK shoulder, but right now it's just checking subfield y.

Configuration

We use a fairly standard configuration. The default configuration information is here: https://github.com/ProjectMirador/mirador/blob/master/src/config/settings.js and documented via comments
