If we attribute to the spacetime continuum a microstructure, it can be geometri cally described by means of a pseudo-Riemannian metric and an independent linear connection. Besides energy-momentum, such a metric-afnne spacetime can carry hypennomentum (generalizing spin), the intrinsic part of which is induced by manifields, that is, by infinite-component representations of the affine group GA (4, R).
