DIAMOND: a system for computing with abstract dialectical frameworks. This paper briefly describes the DIAMOND system, version 2.0.0, in its role as submission to the First International Competition on Computational Models of Argumentation (ICCMA). DIAMOND is essentially a collection of answer set programming (ASP) encodings of semantics of abstract dialectical frameworks (ADFs) together with a wrapper script that calls an ASP solver with adequate encodings for a given instance, semantics and reasoning problem.
