DFT calculations lead to low-energy effective models. A modern example would be Kitaev types spin Hamiltonains for RuCl3. Once the model is specified, many different many-body calculations can be carried out. We will present our draft for a universal metadata standard for defining these lattice models. The goal is to have a common language that enables interoperability between the numerous different algorithms and codes used for simulating condensed matter lattice models.
