  The comparison of experimental data and theoretical predictions is important
for our understanding of the mechanisms for interactions and particle
production in hadron collisions, both at the Large Hadron Collider and at the
Relativistic Heavy-Ion Collider experiments. Several tools were ideated to help
with that. Rivet (Robust Independent Validation of Experiment and Theory) is a
framework that facilitates the comparison between measurements from high-energy
physics experiments and Monte Carlo event generators able to produce outputs
using the HepMC package. Rivet contains a repository with analysis algorithms
developed by experiments, providing analysis documentation and preservation.
  The recent development of features for the implementation of heavy-ion
collision analyses, such as centrality determination, will be presented in this
contribution, together with some of the open points still to be addressed.
