Deploying web services on Shop Floor devices in a manufacturing enterprise extends the Service Oriented Architecture (SOA) to the device level, bringing Shop Floor and Enterprise computing resources closer to each other. In this paper, we further extend the SOA landscape towards cross enterprise scenarios, which benefit adaptive manufacturing to be extremely flexible till the last stages of production. A method using mash up of web service technologies like DPWS, BPEL and eSOA, is employed in this work. Possible methods to implement Web Services on wireless sensor nodes like SunSPOTs are also examined. These methods could be used together as an experimental platform to evaluate a new paradigm of factory automation and enterprise computing, in which shop floor real time data are easily accessible from the business level and can be shared among enterprises. This brings a new way of cross enterprise computing called Shop Floor Commerce.
