A Standard Grammar for Temporal Logics on Finite Traces

Abstract: The heterogeneity of tools that support temporal logic formulae poses several challenges in terms of interoperability. In particular, a standard syntax for temporal logic on finite traces, despite similar to the one for infinite traces, is currently missing. This document proposes a standard grammar for several temporal logic formalisms interpreted over finite traces, like Linear Temporal Logic (LTLf), Linear Dynamic Logic (LDLf), Pure-Past Linear Temporal Logic (PLTLf) and Pure-Past Linear Dynamic Logic (PLDLf).
