DLN is a recent approach that extends description logics with defeasible reasoning capabilities. In this paper we provide an overview on DLN, illustrating the underlying knowledge engineering requirements as well as the characteristic features that preserve DLN from some recurrent semantic and computational drawbacks. We also compare DLN with some alternative nonmonotonic semantics, enlightening the relationships between the KLM postulates and DLN.
