We discuss the interface between the current theoretical framework based on generalized parton distributions (GPDs) and experimental measurements of deeply virtual Compton scattering (DVCS) observables. We point out that the theoretical framework of GPDs relying on handbag dominance is not sufficient to cover the kinematic region of DVCS experiment with the 12 GeV upgrade at Jefferson Lab. For the general theoretical framework to cover the current and future DVCS experiments, we propose the method of finding the most general hadronic tensor structure with the Lorentz and gauge invariant Compton form factors (CFFs).
