AB The concept of Generalized Parton Distributions promises an understandingof the generation of the charge, spin, and energy-momentum structureof hadrons by quarks and gluons. Forthcoming measurements with unprecedentedaccuracy at Jefferson Lab and at CERN will challenge our quantitativedescription of the three-dimensional structure of hadrons. To fully exploit thesefuture measurements, new tools and models are currently being developed.We explain the difficulties of Generalized Parton Distribution modeling, andpresent some recent progresses. In particular we describe the symmetrypreservingDyson-Schwinger and Bethe-Salpeter framework. We also discussvarious equivalent parameterizations and sketch how to combine them to obtainmodels satisfying a priori all required theoretical constraints. At last weexplain why these developments naturally fit in a versatile software framework,named PARTONS, dedicated to the theory and phenomenology of GPDs.
