Computer science description: We introduce COWS (Calculus for Orchestration of Web Services), a new foundational language for SOC whose design has been influenced by WS-BPEL, the de facto standard language for orchestration of web services. COWS combines in an original way a number of ingredients borrowed from well-known process calculi, e.g. asynchronous communication, polyadic synchronization, pattern matching, protection, delimited receiving and killing activities, while resulting different from any of them. Several examples illustrates COWS peculiarities and show its expressiveness both for modelling imperative and orchestration constructs, e.g. web services, flow graphs, fault and compensation handlers, and for encoding other process and orchestration languages. publisher: Springer contributor: De Nicola, Rocco date: 2007 type: Book Section type: PeerReviewed format: application/pdf language: en identifier: http://eprints.imtlucca.it/416/1/cows_esop_2007a.pdf identifier: Lapadula, Alessandro and Pugliese, Rosario and Tiezzi, Francesco A Calculus for Orchestration of Web Services.
