A Composable, QoS-Aware and Web Services-Based Execution Model for ebXML BPSS Business Transactions

The implementation of cross-organizational processes in the context of Business-to-Business integration (B2Bi) requires extensive communication between all interacting parties and adequate solutions for the integration of existing IT systems. In the SOA domain, choreography languages have been put forward for the specification of the publicly visible message exchange sequences of interacting parties. Choreography models serve as basis for communication between stakeholders and as reference for aligning business services which is a core SOA concept.However, visual choreography modeling guidelines that are both, tailored to B2Bi and unambiguous in semantics, have not been proposed so far. This paper fills in this gap by showing how BPMN choreography notation can be used to represent socalled B2Bi choreographies with unambiguous semantics. The work has been validated by a series of real-world use cases of the RosettaNet community and has been accepted by the RosettaNet Message Control and Choreography team as core part of a RosettaNet standard.

ebXML BPSS (ebBP) is well-suited to specify Business-to-Business (B2B) interactions as choreographies of so-called BusinessTransactions. Web Services and WS-BPEL as dedicated interface technologies then can be used to provide the implementation of such choreographies. Tracking and ensuring the progress of choreographies calls for monitoring facilities that require gathering information from log data of the runtime systems that execute WS-BPEL processes. However, the information provided by WS-BPEL monitoring tools is fine-granular so that information about the actual progress in terms of choreographies must be extracted manually. Our approach streamlines the monitoring of ebBP BusinessTransactions leveraging model-driven engineering. First, hierarchical communicating automata are used to formalize BusinessTransactions. Second, WS-BPEL implementations of these automata are derived such that monitoring events are propagated to a monitoring service whenever a transition of the underlying automaton fires. Third, the monitoring service translates the monitoring events into choreography progress by visually highlighting the active and visited states within the hierarchical automata. It thus presents a user-friendly model that abstracts from the details of the implementing WS-BPEL processes. This makes tracking the current state of choreographies accessible to business users.

“…Due to space limitations, we are only presenting the WS-BPEL mapping of a 'leader'-type BCA control process, but the rules for mapping 'non-leader'-type processes are symmetric. Further, the description of how to implement BTAs is not presented because a fully compatible solution is available in [5]. Note that the mapping of ebBP-Reg into WS-BPEL is designed such that it can easily be automated, although the prototype was created manually (cf.…”

“…A formalization of well-formedness rules for ensuring validity and executability of process models is not provided. Finally, there are several publications like [20] or [5] that only target at performing isolated ebBP BusinessTransaction like concepts as WS-BPEL orchestrations and leave out composition.…”

Towards Executing ebBP-Reg B2Bi Choreographies

Applying choreography and orchestration technology to Business-to-Business integration (B2Bi) scenarios has become a popular technique for very good reasons. Choreography descriptions can be used to capture B2Bi scenarios from a global and abstract perspective while orchestrations then can be used to specify the local implementation of each integration partner. ebXML BPSS (ebBP) is a prominent B2Bi choreography standard with very helpful domain-specific concepts, but clear guidelines for creating executable choreographies are missing. In order to create ebBP models that are both adequate and executable, expressiveness, comprehensibility and standard-conformance have to be weighed up. In this paper, we introduce ebBP-Reg as an ebBP modeling flavor that is designed such that ebBP-Reg choreographies are executable as WS-BPEL orchestrations. At the same time, ebBP-Reg models strictly conform to the ebBP standard and support concurrency and decomposition. We characterize syntactic validity of ebBP-Reg models by means of language production rules and show how instances of ebBP-Reg can be implemented using WS-BPEL.
