Is it important to have a "book view" for paged content?

[jabrah]

Currently, paged content is rendered using Mirador, but is configured in a way that will display only one image at a time. Is it important to view paged content with the left and right sides of an opening visible side by side?

Here's an example from the Mirador instance used in AoR:

Single view

"Book" view

If we want to enable the book view, I believe we'd need to add a viewingHint: paged to the generated IIIF sequences (this can be done in idc_ui_module/plugin/views/style/IDCIIIFSerializer)

acceptance testing had not raised an issue with our current pdf display. So we wont take on this work unprompted.

This would be applicable to Paged Content repository items.\

Firstly, we would need to update our generated IIIF manifests to add the viewingHint: 'Paged' on the Sequence (only on Paged Content items) here in this PHP file: https://github.com/jhu-idc/idc_ui_module/blob/main/src/Plugin/views/style/IDCIIIFSerializer.php

We'd need to modify our Mirador config (https://github.com/jhu-idc/idc-ui-theme/blob/main/js/packages/mirador/index.js#L35-L65), by adding

config.window.views = [
  { key: 'single', behaviors: ['individuals'] },
  { key: 'book', behaviors: ['paged'] },
];
config.window.allowTopMenuButton = true; // Change from 'false' to 'true'

This will add a button to the top menu, which, when clicked, will open a control panel that would let a user choose view modes.
.

Optionally, we could change config.windows.view to 'book'``, from 'single'`. This would show the "book" view by default instead of the single image view.
