One of the flaws of using Digital Mappa for projects like this appears to be that it acts more as a viewer (as a result of it's original use with maps) than as something for text. As a result, when looking at various pages, the URL of the page and it's attendant resources doesn't change, so one can't link to particular resources within the work, nor can one easily use digital tools (Hypothes.is for example), to anchor and annotate portions of the text.
