An architecture for the integration of Grid applications with a Catallactic middleware is described, along with an analysis of issues associated with this integration in a real world deployment scenario. This approach makes use of the economic concept of "Catallaxy", which understands a market as a decentralised and self-organizing coordination mechanism, as opposed to a centralised command economy. A prototype is described which consists of an existing Grid application making use of a distributed query service. The Catallactic middleware has been implemented using Globus Toolkit 4, Web Services Resource Framework (WSRF) and WS-Agreement. The evaluation of this prototype shows the feasibility of offering existing Grid applications in a computational market, and demonstrates how the middleware based on market mechanisms can in effect be used to balance query request workload across multiple Grid services.
