Please see the following video that explains the proposed approach for a compound viewer: https://drive.google.com/drive/u/0/folders/1oJmAsf8KHt-1YhJ3NSPS_bJ5eTRrNJ2_

Compound Object Viewer provides a lightweight approach to display media associated with compound object’s members, and to navigate between them.

It uses two views, one to set up the service file display, and other to setup the Compound Object Members thumbnail navigation.

A hook function is used to load the media or the service file of the first member object. The user can select to view any other member media by clicking on the thumbnail navigation below. Currently, the members are sorted by node id; however, other fields such as the field_wieght can be used to sort the order of the members as well.

A javascript function is used to highlight the selected member object.

Differences with the current sandbox compound viewer version

• When the user clicks on the compound object, it does not go to the first member object node. It goes to the compound object node, then loads the first member's service file.
• Currently, it does not provide Item and Set descriptions. However, this can be added on after a metadata display approach is selected for the islandora starter site.

Known Issues

• Currently, if the member media does not have thumbnail, it does not load get loaded in the navigation block. This will be addressed.
• Accessibility of the navigation panel needs to be tested, and aria labels would need to be added.
