Well, I haven't looked much at MusicXML, so I can't really comment
there. However, with Lilypond, look for a \header block (Lily syntax is
sort of similar to TeX, since it translates to TeX which actually does
the typesetting). It looks something like:
\header {
title = "Floopsy Wumpus"
subtitle = "Part XXIV"
composer = "Gertrude Q. Wooketyflurp"
}
The key is embedded in the tune (in each voice); it looks something like
"\key c \minor" or "\key bes" (it uses Dutch note names, so "is" =>
sharp, "es" => flat, thus "bes" is "B flat"). If no "\minor" or
"\major" appears, it defaults to major.
Hope that helps!
