Abstract
We introduce B \(\mathit{lite}\), 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 \(\mathit{lite}\) 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 \(\mathit{lite}\) 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.
