That was a bit above my head!
In kinematics, i can take a "rigid" set of points as a Frame, if someone can assure me that it is not rotating but moving only translation. If any other set of points is moving only in translation w.r.t. the above "certified" frame, that also can be accepted as a frame.
Absolute rotation of only a material frame can be detected by the inertial forces
