Abstract

Dynamic adaptation is provided within web service composition and execution. Within a logical composition stage, a set of abstract workflows for a web service is selected from a number of generated abstract workflows. Within a physical composition stage, a set of executable workflows is selected from a number of executable workflows that are generated at least based on the set of abstract workflows selected. Within a runtime stage, an executable workflow to be executed is selected from the set of executable workflows and that particularly satisfies specified requirements. The executable workflow selected is executed within an execution environment. The executable workflow within the runtime stage, the set of executable workflows within the physical composition stage, and the set of abstract workflows within the logical composition stage are periodically dynamically assessed and reselected.
