Here is an example of what were producing so far for book 5 "the omens": https://github.com/ftyers/UD_Classical_Nahuatl-FloCo/blob/ma...

The repo is kind of messy, it's mostly me and some students working on it, but we're pretty passionate. Let me know if you'd like to get involved! :)

Note that the annotation is alignable with images of the original manuscript, which are online at the Library of Congress. I.e. https://www.loc.gov/item/2021667850/

The [orig] contains all the original token and line breaks.

That's really cool. I went deep into epigraphy when I lived in Guatemala and was regularly finding carved pottery in our garden beds. Spent a lot of time annotating paper copies of glyphs.

What's the way to view/edit the .conllu files?

They're generated from a tonne of Python scripts, but feel free to get in contact and I can take you through how it works ! :)
