Abstract

We introduce the inference queue as a mechanism for communicating and transforming data in Web services choreography. The insert operation provides definite clauses to the inference queue, and the remove operation generates output that is sound, complete, fair, and irredundant. Both operations are thread safe and responsive. The inference queue can form part of a highly configurable data transformation system. Rules can also monitor for events of interest based on the occurrence of certain conditions. Our suggestion of system wide monitoring of communication is complementary to existing Web services proposals.
