Service oriented computing from the user perspective

International audienceThe last decade has attracted lot of research work in Service-Oriented Computing (SOC), giving raise to standardized architectures, protocols, and technologies that enable developers to easily expose and reuse services. However, these technologies do not fully consider the users as potential actors in the creation of services based on existing ones, as advocated in Web 2.0 paradigm. In this presentation, we first summarize SOC and its intrinsic SOA paradigm. Second, we propose a new approach based on Widgets. We propose the Widget-Oriented Architecture (WOA); a new paradigm to enable a user-centric service reuse. Third, we show how the WOA is applied in two SOA application fields, namely service composition and business process managemen
