Well... by "native", I meant, a format which Octave can read directly
into some meaningful structure without having to code specific routines
to parse it. hdf5 seems to fit that.

hdf5 looks good, but I'm not sure how much work it would be to implement
in gnucap - it looks slightly complicated! At least there are some
libraries for it though.

It seems like hdf5 is fairly generic - so we'd need to define some
structure + datatypes of what we store.
