| description | We introduce a meta-model based on formal languages, dubbed formal
choreographic languages, to study message-passing systems. Our framework allows
us to generalise standard constructions from the literature and to compare
them. In particular, we consider notions such as global view, local view, and
projections from the former to the latter. The correctness of local views
projected from global views is characterised in terms of a closure property. We
consider a number of communication properties -- such as (dead)lock-freedom --
and give conditions on formal choreographic languages to guarantee them.
Finally, we show how formal choreographic languages can capture existing
formalisms; specifically we consider communicating finite-state machines,
choreography automata, and multiparty session types. Notably, formal
choreographic languages, differently from most approaches in the literature,
can naturally model systems exhibiting non-regular behaviour. |
