If you look on Project Gutenberg, they have all of the different filetypes already created and stored, probably with a database.

Nostr already has a database, tho (relays, an event store), where we're storing the books as events, which are the smallest, simplest building blocks of such documents. So we can always work parts-to-whole and generate any other view on the fly, including HTML. With a book, you don't need the speed and convenience of a websocket, as the text hardly changes and there's hardly any interaction. It's just you, staring at a long text, occasionally highlighting something interesting, and maybe submitting a review of the book, at the end (like we do for relays).

 Markdown, usually. I think some are using asciidoc, too, or both. 

 Yes, we would just need an online generator, were you can fill in the fields for a 30040 and then attach all of the md files you want to include in that batch, and have it write the events. 

 The event content itself is Markdown, I believe.  Like Læserin mentioned, some clients may switch to ASCIIDoc.  We'll probably need to support both, eventually, but Markdown is a good start.

So we need a Markdown-to-HTML converter, and eventually an ASCIIDoc-to-HTML converter.

The API endpoint workflow would be:

1. Look up 30040 event and associated 30041 events (or single 30041 event to return a chapter at a time, but that's implementation details).
2. Tie together the Markdown contents or relevant events into a single giant Markdown string/stream.
3. Pass the string/stream through a converter to produce HTML.
4. Return HTML to the caller. 

 I’ll start playing around with this. I’ll just leave room for adding asciidoc later, as I’m not super comfortable with it. 

 I hadn't even heard of asciidoc until recently.  Not worth worrying about too much at the moment, since most clients are still on Markdown. 

 Im going to have fun playing with VS’s docker stuff for this. Should make it easier to self-host too. Thanks for a (conceptually) simple thing to play with. 

I’ll regret saying that later, but çest la vie. 

 "Oh it looks simple" (famous last words)

That's how I feel about the NIP-46 signing for Aedile.  It's a hefty piece of work for a relatively simple concept.
