There's a description of the DB "schema" in lib/database.cc in the
notmuch source code. But you may also consider just using libnotmuch
instead, if that's enough for what you want to do.

Also: why Xapian? I'm already using something similar I wrote with
Python, storing everything in a dictionary, using Pickle to save that to
disk: 162 lines of code and 45 kb of data are enough to store my
addressbook and have completion in Emacs...
