ResumoThis chapter describes the state-of-the-art in context-aware computing and discusses the goals, motivation, and requirements that define the actual need for context awareness in order to achieve a better understanding of the concepts involved. It reviews the trends for its use in converging service-oriented architectures. Interoperability at the scale of the Internet of Things should go beyond syntactical interfaces and requires the sharing of common semantics across all software architectures. The chapter illustrates how to integrate existing technologies and computational artifacts supporting context awareness as an enabling service amongst other building blocks in an overall service-oriented architecture for use in home appliances and online consumer services. Service Oriented Architecture (SOA) represents the state-of-the-art in software architecture for the rapid deployment of new services. A service in SOA is essentially transaction-based and relies on an architecture that often builds upon the functionality of an enterprise service bus to provide message brokering, routing, data translation, and transformation.
