Computer science description: We introduce B lite, a lightweight language for web services orchestration designed around some of WS-BPEL peculiar features like partner links, process termination, message correlation, long-running business transactions and compensation handlers. B lite formal presentation helps clarifying some ambiguous aspects of the WS-BPEL specification, which have led to engines implementing different semantics and, thus, have undermined portability of WS-BPEL programs over different platforms. We illustrate the main features of B lite by means of many examples, some of which are also exploited to test and compare the behaviour of three of the most known free WS-BPEL engines. publisher: Springer contributor: Lea, Doug contributor: Zavattaro, Gianluigi date: 2008 type: Book Section type: PeerReviewed format: application/pdf language: en identifier: http://eprints.imtlucca.it/410/1/blite_2008e.pdf identifier: Lapadula, Alessandro and Pugliese, Rosario and Tiezzi, Francesco A Formal Account of WS-BPEL.
