      abstract     = {We propose a novel, data-driven method for determining
                      total charm cross sections in proton-proton collisions by
                      extrapolating measured fiducial cross sections without
                      assuming any particular fragmentation model. In this way,
                      the method accounts for the recently observed charm
                      fragmentation non-universality at the LHC through a
                      data-driven extrapolation function called ddFONLL. Applied
                      to $D^0$ production at 5 and 13 TeV, this approach yields
                      total charm cross sections that fully incorporate
                      fragmentation non-universality. The results, which differ
                      significantly from previous universality-based estimates,
                      are consistent with NNLO QCD predictions and enable direct
                      comparisons free from fragmentation assumptions. We use this
                      to evaluate the sensitivity of total cross-section
                      measurements to parton distribution functions and the
                      charm-quark mass. An outlook is given on the potential of
                      further expanding the use of the ddFONLL method.},
