I'm working on a NUD draft, at this very moment, because we need it for the Euler (v0.2.0) edition of #Alexandria, due to the focus on research papers. I think you'll like it because it'll include something novel for Nostr to specialize in.

Once you figure those two things out, the citations are WORA, and the client dev can format them however they like.
