Developers write Web service composition programs interms of functionalities (e.g., "WebSearch") to postponechoosing which services of the same functionality to invoke(Google or Yahoo). We provide a higher level of abstractionthan this for higher reuse. We express high-level "patterns"(e.g., "SearchAndCollectData") as both objects that canbe "specialized" to particular applications ("SearchAnd-DownloadPapers"vs. "SearchAndAddBooksInCart") andobjects that are reusable in the construction of higher-levelones. Our approach lets developers write patterns interms of high-level functionalities (e.g., "CollectData") andlater decide on services to compose that have lower-levelfunctionalities (e.g., "DownloadPapers" or "addBooksIn-Carts").We describe our prototype and show an exampleof nested pattern specialization. We also discuss a reusetrade-off, showing that too much abstraction makes the patternless expressive. Rather, we suggest developers capturewhat must be guaranteed in every context of invocation, regardlessof the service selection.
