The copious production of charm quarks at HERA yielded measure- ments of the charm contribution to the proton structure and of the charm mass and fragmentation parameters of charmed hadrons. Several measure- ments of charm production in deep inelastic scattering from the H1 and ZEUS collaborations as well as combined data are presented. They provide a powerful vindication of the form of the gluon density in the proton de- rived from scaling violations of inclusive deep inelastic scattering data. A QCD fit to the charm data leads to a measurement of the charm mass and provides precise predictions e.g. for W and Z production at the LHC. In ad- dition, charm fragmentation fractions in photoproduction to ground state charm hadrons are compared to e + e
