Subject: 11/14/2003: Use Case Catalog - simple-eb
John, In reviewing the use case catalog to date, I see we may need to clarify/understand some of the aspects of Simple-eb and how this affects some of the assumptions in WS-BPEL. For example: * Data alignment: If you take the premises of Global Data Synchronization and data alignment, it is somewhat assumed that a 'pool' of data relevant to the related parties prior to any message interchange. Therefore, the actual message exchange may be limited to the changed data assumed by the parties or the relevant data specific to that interaction. Therefore this may not align with the assumptions made with correlation sets unless instance specific details are exchanged that allow that correlation. Something to think about. The actual message exchanges could be limited to a finite data set and not representative of what we typically see in automated message exchange (although you may be able to model the interactions at an abstract level). * BPSS implementation: Can you explain how Simple-eb could be mapped to the BPSS implementation based on the V20030922 UMM metamodel or user guide? The Simple-eb work and subsequent BPSS implementation occurred prior to that release. Perhaps you can explain. Thanks.
