  We utilize the DVCS asymmetry measurements of the HERMES collaboration for
access to Compton form factors in the deeply virtual regime and to generalized
parton distributions. In particular, the (almost) complete measurement of DVCS
observables allows us to map various asymmetries into the space of Compton form
factors, where we still rely in this analysis on dominance of twist-two
associated Compton form factors. We compare this one-to-one map with local
Compton form factor fits and a model dependent global fit.
