Building the Web of Things With WS-BPEL and Visual Tags
The Web of things is an emerging scenario in which everyday objects are connected to the Internet and can answer to HTTP queries with structured data. This paper presents a system that allows users to build networks of everyday objects using visual tags as proximity technology. The system back-end is based on Service-oriented Architecture languages and tools for the run-time composition of "Things" establishing connections the authors call hyperpipes. The Web of things is an emerging scenario in which every object is connected to a pervasive wireless/wired network and can answer to a HTTP query with structured data. Everyday surrounding objects like phones, domestic appliances, advertisement billboards, musical instruments become the nodes of the Web of things.
