 This article introduces the notion of dynamics for abstract argumenta-tion frameworks. We consider evidence as the basis from which arguments may beconsidered valid. The proposed Dynamic Argumentation Framework (DAF) is arefinement of Dung?s abstract framework (AF), enriched with additional features.Since an instance of a DAF is equivalent to an AF, the former could be viewed asa template to build different AFs, applying the same knowledge to different situa-tions. This equivalence is important, as we can take advantage of the vast amount ofstudy on argumentation semantics for AFs to apply it to our approach. The DAF?saim is to provide a well-structured knowledge representation tool that allows forthe definition of dynamics-aware argumentation-based systems.
