Abstract. Software tools for working with argument generally exist as large systems that wrap their entire feature set in the application as a whole. This approach, while perfectly valid, can result in users having to use small parts of multiple systems to carry out a specific task. In this paper, we present a series of web services, that each encapsulate small pieces of functionality for working with argument. We then demonstrate two example systems built by connecting these services in the form of a UNIX-style pipeline. Keywords. Argumentation Engine, Dung, Dungine, Dung-O-Matic, Web Services
