Abstract
Epistemic planning is a branch of Artificial Intelligence that stems from the combination of automated planning and Dynamic Epistemic Logic (DEL). While DEL provides a very expressive framework---which comes at the cost of undecidability---to guarantee the feasibility of the planning process, various fragments have been studied in the literature, that rely on very specific syntax for representing domains. As a result, a comprehensive language that is able to capture the general DEL framework is currently not present in the literature. In this paper, we propose a new language called EPDDL (Epistemic Planning Domain Definition Language), through which we can capture the full DEL semantics, thus allowing for a general and unified syntax for representing epistemic planning domains.
