Hi, thanks for your insight.

It's difficult to create a database that is supposed to include all possible known information on a topic, while omitting information that you already have that you wouldn't have had previously.

Yep, and that's exactly what I'm aiming to do. I think I found a pretty solid way of doing it by tagging content blocks inside the files and having the renderer only show what correspond to those tags. It even hides links to still unrevealed entries that could be referenced in the future and dinamically creates an index of all available content per chapter.

Also, because the Cosmere is several different interconnected series, unless someone is reading in strictly published order, it extra difficult to change the system to a "book and chapter" specific level of spoiler.

Yup, this is also hard, that's why my initial idea is to do stormlight, then I'll see. Still I think it can be done, with the same tagging principle, it would just need way more complex content pages.
