Classifications for Fedra?

I'm compiling a list of typefaces and trying to apply classifications beyond simple categories, the categories being sans-serif, serif, slab serif, etc. The Fedra family is a little tough. What would Fedra Serif be? I've seen the category "contemporary" applied to it, but that seems to be a little "dated", as the definition of contemporary will always change. I've seen Humanist applied to Fedra Sans, which makes sense.

So what is the best classification for Fedra Serif? Best for Fedra Sans?

Thanks
