The new pervasive and ubiquitous computing model has led to the development of modern environments which are responsive to the changing needs of the people who live, work or socialise in these environments. To achieve this level of intelligence, such environments collect, store, represent and interpret a vast amount of information which describe the current context of its users. The aim of this research is to develop a generic and extensible architecture for the construction of pervasive context-aware systems that can be applied to various smart environments. Most of existing context-aware architectures are application specific using fixed components; such components are difficult to change or extend to cope with new requirements requiring new contexts. To address these issues, we present a generic framework using the Pipe-and-Filter architectural style. This framework and architecture use a model to represent raw context information as a function of context primitives, known as 4W1H.
