We will review the status of hard exclusive process measurements at
Jefferson Lab with a particular emphasis on Deeply Virtual Compton
Scattering (DVCS) which is uniquely accessible at this laboratory at
moderate energy. The measurement of asymmetries and cross sections for DVCS
constrains the Generalized Parton Distributions of the nucleon and therefore
gives new information on its structure. We will comment on the
the possibility to perform similar studies at moderate energy using
exclusive electroproduction of mesons.
