I love the h5py package so I keep recommending it (and pytables is supposed to be good, I think?). h5py stores files in hdf5, which is readable from C,C++,fortran,java,python... It also keeps track of shape and you can store other metadata (e.g. strings) as desired.

Also I believe the numpy format (see e.g. http://docs.scipy.org/doc/numpy/reference/generated/numpy.savez.html#numpy.savez) can do the same, although I don't think performance scales as well for huge arrays, and it's not language-neutral (to my knowledge).
