Optimizing queries over XML streams has been an important and non-trivial issue with the emergence of complex XML stream applications such as monitoring sensor networks and online transaction processing. R-SOX provides a platform for runtime query optimization based on dynamic schema knowledge embedded in the XML streams. Such information provides refined runtime schema knowledge thus dramatically enlarged the opportunity for schema-based query optimizations. In this paper, the focus is on the following three aspects: annotation of runtime schema knowledge; incremental maintenance of runtime schema knowledge; dynamic semantic query optimization techniques.
