Measurements of 
meson production in diffractive deep inelastic scattering 
are presented which are based on HERA data recorded at a centre-of-mass energy 
with an integrated luminosity of 287 pb
. The reaction 
is studied, where the system X, containing at least one meson, is separated from a leading low-mass proton dissociative system Y by a large rapidity gap. The kinematics of 
candidates are reconstructed in the 
decay channel. The measured cross sections compare favourably with next-to-leading order QCD predictions, where charm quarks are produced via boson-gluon fusion. The charm quarks are then independently fragmented to the mesons. The calculations rely on the collinear factorisation theorem and are based on diffractive parton densities previously obtained by H1 from fits to inclusive diffractive cross sections. The data are further used to determine the diffractive to inclusive production ratio in deep inelastic scattering.
