Abstract :
Pervasive applications want to describe in simple ways which context information they need about users, and be notified when low level context matches specified constraints defined by semantic expressions. In this paper we report our experience while implementing our Context Query Language and using it in a real context framework to support mobile context-aware applications in two European-funded projects. Our experience has shown that both the language design and its implementation are suitable to support complex asynchronous high-level context notification requirements from applications.
