Digital Collections Review Project: FAQs


Compound Objects

What is a compound object?

Compound objects are records with more than one object or item attached to the record.

For example, a cookbook with 84 pages can be a compound object. The cookbook is the main record, but all the pages are child items that attach to the main record. Compound objects can display in a side scroll view or a book view.

An oral history with a transcript can be a compound object. The video or audio recording of the oral history is one object and the transcript a second object, but they are usually linked to the same parent record.

To see examples of those views, see below.

Side Scroll View or Book View?


The main viewer in IDL is powered by OpenSeaDragon. That's what allows images to zoom in and out, rotate, and perform other transformative tasks.

For records with multiple items or object attached (e.g., multiple pages, video and transcript, audio and document) there are two different views.

Side Scroll View

This view places multiple pages or items in a side scroll tray alongside the main view window.


Book Viewer

This view places multiple pages or items into a page flip view.

Facets and Metadata


Facets are available when viewing search results to help narrow down by Collection, Creator, Topical Subject, Geographic Subject, Chronological Subject, Date Created, Genre, and Series. 


Metadata are available below the item in the record. Scroll down to see metadata under Description.

Where's the Metadata?

Some images will appear to have little to no metadata. That usually indicated the item is a CHILD item. Look for the Breadcrumbs at the top of the record and click on the title of the PARENT record to see full metadata.
