How does Talis Aspire Digitised Content (TADC) treat my PDFs?

How does Talis Aspire Digitised Content (TADC) treat my PDFs?

When a PDF is uploaded into a digitisation request, TADC performs the following:

  1. Generates a single page coversheet with the necessary information from the request. Note: A new coversheet is generated for each request.
  2. Begins the packing process to create a 'bundle'.  This combines the TADC generated single page coversheet with the originally uploaded PDF into a new PDF. From this we generate an image of every page in the 'bundle' - this is what is served to the user when they are viewing a bundle in the application.

When is the coversheet updated?

Once you have updated information within a 'Live' digitisation request the bundle will be repacked with an updated coversheet reflecting the changes you have made to the request.  This will be documented in the request's worklog.


What does this mean for accessibility?

When viewing a bundle Onscreen:

Bundles are presented on screen within the viewer. Currently, the viewer does not provide any hidden text for screen readers.

Downloading the bundle:

If the original PDF had been created for accessibility purposes, then this would continue to be the case if the user downloaded the bundle and opened in a PDF player that included screen reading capabilities e.g. the PDF reader in Adobe or the OSX PDF player with VoiceOver enabled.

The coversheet has no accessible information purposefully built into it, however, some testing we have done against Adobe Reader and OSX Preview player indicate that some screen readers will be able to read the coversheet.
