LUNA 7.5.2 introduces IIIF content at your fingertips! This game changing release supports our user community by expanding on IIIF technology and the LUNA Shared Collections feature. LUNA administrators can now add any IIIF enabled non-LUNA content to their own LUNA instance. We're talking about being able to add images from The Yale University Map collection, The Smithsonian Freer Gallery and many more notable sources that have implemented IIIF.  Along with several other feature updates, the release also includes a variety of bug fixes.

New Features in LUNA 7.5.2

IIIF Features

  • Introducing an innovative new feature that allows for adding IIIF enabed non-LUNA content into LUNA. Any IIIF enabled collection or group of images can be added to your instance of LUNA. Choose from our curated list of non-LUNA content or create your own by following the instructions in our documentation.

  • Related to adding IIIF enabled non-LUNA content, we created a utility/script that will take a list of iiif manifests and convert them to a iiif collection. This utility and feature allows the LUNA admin to curate their own groups of content for representation in the LUNA Viewer.

  • Implemented a dashboard for the Sharing Tools which includes links to:

    - The Task Scheduler page to add/edit shared LUNA collections
    - A new page where you can add non LUNA content in the form of json files
    - A list of LUNA and non LUNA collections for admins to easily choose from add to their own LUNA instance


  • Enhance support for annotations in the Viewer's Mirador Detail View, using Open Annotations. Users can search for annotations and they can be displayed as descriptive metadata in the Detail View’s Media Information panel. Private annotations are also supported in this release.

Collection List Panel in Viewer

  • Removed the collection list panel completely for LUNA instances with only one collection.
  • If there are no shared collections in the Viewer, the Institution name at the top will not display.
  • If there are no collections assigned to Categories, the View Categories option in the drop down menu and on collection list panel will not display

Collection Display

  • Changed the default theme to automatically be set to Modern (white) when a new collection is created. Also changed the theme selection language to:

    Modern (white)
    Deep Sea (blue)
    Earth (brown)

Other Viewer Enhancements

  • Replaced Flowplayer with Video JS and added support for closed captioning using vtt files.
  • Updated to the Mirador 3 interface in the LUNA Viewer, beta version.
  • In the Viewer, for Mirador 2 only, implemented the rotate icon to the controls bar in the Mirador Detail View.
