fo a personal project I have the need to describe a leparello in IIIF.
Some of you might be aware what I'm referring to, but since I haven't found a direct translation from this German word except the adjective "fanfold", let me point you to a link which, in my opinion, illustrate this and why Im asking this question:
As you can see it's a folded leaf of (in this case) an illustration. It also can be something else like an advertisement. Sometimes these can also have page numbers, are maps and sometimes similar structures can be part of a bound book.
The example shows a somewhat less than perfect way of displaying such a document. It features some sort of overview as the first page and then each page as a single image.
What I'm exactly looking for is some guidance how to encode these, preserving the information which pages belong to one "page context" or side. Like two facing pages in a book - for a 12 "page" leparello 6 facing pages displayed in one go.
Maybe I'm just blinded by the term "leparello" here and IIIF supports this use case just under another name?
Don't get me wrong, I'm not asking whether this encoding can be displayed by any viewer, I've already figured out that there is no requirement for compliance with the IIIF specification for IIIF viewers.
I'm happy for your suggestions.
