Re: [ebxml-bp] Manual Operations in BPSS"

[Duane Nickull <dnickull@adobe.com>]

The messaging, when implemented properly with CPA, can accomplish this.

CPA specifies a "time to persist" for each in or outbound message.  If a 
system goes down, by building an audit trail of outgoing and incoming 
messages, it can determine the outward state of the process.  This 
places a dependency on using the CPA and a process script correctly. 
 CPA will work today however version 1.01 of BPSS did not (as I had 
noted in 2001 when I stood up in Vienna).

The requirements on BPSS to perform an audit mean that it must be able 
to constrain each step and correlate each transaction from the messaging 
layer of the stack with a specific business signal in BPSS.  

I did an implement ability study two times and it failed but in light of 
the rapid advances in BPSS by this group, feel it may be time to try 
again.  I asked JJ if it was time back in September but he informed me 
not quite yet.  

If someone can verify that they feel this is complete enough to try 
again, I volunteer to try it then report any feedback to this group.
