Measurements are presented of diffractive open charm production at HERA. The event topology is given by ep - GT eXY where the system X contains at least one charmed hadron and is well separated by a large rapidity gap from a leading low-mass proton remnant system Y. Two analysis techniques are used for the cross section measurements. In the first, the charm quark is tagged by the reconstruction of a D*(+/-)(2010) meson. This technique is used in deep-inelastic scattering (DIS) and photoproduction (gamma p). In the second, a method based on the displacement of tracks from the primary vertex is used to measure the open charm contribution to the inclusive diffractive cross section in DIS. The measurements are compared with next-to-leading order QCD predictions based on diffractive parton density functions previously obtained from a QCD analysis of the inclusive diffractive cross section at H1. A good agreement is observed in the full kinematic regime, which supports the validity of QCD fa...ctorization for open charm production in diffractive DIS and gamma p.
