I like to share my research work with HL7 in case some of you would be interested to share some thoughts. The curious issue : Where is the original HL7 message? The ___messages are not tracked as an original flat-file HL7___ when using HAT with the MLLP adapter. And the real deal: 1 Context An integration solution with BizTalk Server 2006/2006 R2 is deployed in production. A new version of the solution was completed and ready to be deployed. However it is not possible to fully assert its quality without running messages in production. I know, please do not "5whys" me on this (http://en.wikipedia.org/wiki/5_Whys). For now, it must be seen as a constraint. The pre-production environment cannot have external systems that would reliably reproduce the production environment. Production messages are highly valuable and must not be ruined by the system. A backup plan is mandatory. The nature of the communication, HL7 exchange, yield to another functional constraint: the receiving se...

I think I may have found an inconsistency with BizTalk promotion mechanism. Context The system is using – roughly – two orchestration super-types: The ones that are publishing business data from external sources to the enterprise data warehouse, and The ones that are subscribing to (wait for) events on the bus and provide data to other enterprise systems for day to day operations. One of the responsibilities of publisher super-type orchestrations is to notify subscriber super-type orchestrations when data is available in the warehouse. Publishers and subscribers do not know each others (no call/send shape or partner ports are allowed). This loosely-coupling behavior is supported with event messages that travel through the message box. Publishers creates the event messages for subscribes in this disconnected mode. Event messages have the same message type and only its inner element values would reveal which concept of data is available. Subscribers may h...
