Context information is characterized by several qualities that make pervasive services challenging compared to conventional Web services. The additional complexities associated with pervasive services require solid software engineering practices. This paper presents a novel approach based on model-driven development for representing complex crosscutting context-dependent functionality in service interfaces...
Software connectors are external coordination devices which ensure the flow of data and enforce synchronization constraints within a component's network. The specification of software connectors through which context dependent behaviour is correctly propagated remains an open, non trivial issue in their semantics. This paper, building on previous work by the authors, revisits this problem and introduces...
As computers and software applications become ubiquitous the systems we build are increasingly required to run on not just a single piece of hardware, but rather be available for different platforms, different types of hardware and offer different modes of interaction depending on the context of use. Within a formal development process when we consider refinement for interactive systems we therefore...
