The formal analysis of critical systems is supported by a vast space of modelling formalisms and tools. The variety of incompatible formats and tools however poses a significant challenge to practical adoption as well as continued research. In this paper, we propose the JANI model format and tool interaction protocol. The format is a metamodel based on networks of communicating automata and has been designed for ease of implementation without sacrificing readability. The purpose of the protocol is to provide a stable and uniform interface between tools such as model checkers, transformers, and user interfaces. JANI uses the Json data format, inheriting its ease of use and inherent extensibility. JANI initially targets, but is not limited to, quantitative model checking. Several existing tools now support the verification of JANI models, and automatic converters from a diverse set of higher-level modelling languages have been implemented. The ultimate purpose of JANI is to simplify tool development, encourage research cooperation, and pave the way towards a future competition in quantitative model checking.
