Since the advent of general relativistic cosmology a century ago, cosmology has progressed from the extrapolative study of a sparse number of astrophysical sources to a precise investigation of the origin and evolution of the Universe. However, the precision in the determination of cosmological parameters in modern data analysis comes at the price of imposing strong a priori assumptions in the modelling of the largest scales of our Universe. I will present strategies for model independent analysis of upcoming cosmological datasets, which allow to infer properties of the Universe without making assumptions about the metric of space-time or the field equations prescribing it.
