      abstract     = {Open data offers new possibilities for a wider audience to
                      access, reproduce and complement active research. In
                      high-energy particle physics many challenges arise, due to
                      several different data formats and large data samples.
                      Therefore, a transformation of the open data to a common
                      data format is used. This enables analysis to be performed
                      within a single workflow and reduces the amount of data and
                      computation time by two orders of magnitude.Here we present
                      an anlysis demonstrator developed in the context of the
                      PUNCH4NFDI consortium showcasing the feasibility of
                      analyzing Open Data from CMS and ATLAS at the same time.
                      Further an example utilizing data from multiple CMS runs
                      will be presented. The demonstrator uses the H → 4ℓ
                      channel and features various levels of complexity to cater
                      to a wide range of users. This framework guides users from
                      basic visualization of the four-lepton invariant mass
                      spectra to producing the four-lepton invariant mass spectrum
                      from transformed datasets within hours.The talk will
                      showcase the latest results of the analysis demonstrator,
                      which may be used as an access point for future open data
                      analysis.},
