摘 要：The main service interoperability models (SOA and REST) are currently implemented in the Web with text based technologies (XML, JSON, HTTP), conceived for large grained hypermedia documents. Their extension to the Internet of Things context, involving devices with constrained capabilities and unreliable wireless network protocols, implies using a subset of the features of those technologies and adapting the network and message level protocols. This chapter starts by establishing a layered interoperability framework, from the organizational down to the network protocol levels. Then, it assesses the constraints and limitations of current technologies, establishing goals to solve these problems. Finally, a new interoperability technology is presented, based on a distributed programming language (and its execution platform) that combines platform independence and self-description capabilities, which current data description languages exhibit, with behavior description (not just data), elimination of the need of a separate language for schema or interface description, complete separation of data and metadata (optimizing message transactions) and native support for binary data (eliminating the need for encoding or compression).
