Requirements on BPEL abstract process

Title: Message

Further to our 
discussions on the 28 May 04 Teleconference, I suggest that the abstract process 
sub-group produces a document that contains requirements on abstract processes 
(with the aim of scoping a language for describing abstract processes), and 
possibly some illustrative use cases / scenarios as well.  This document 
should be presented back to the main TC when we have a reasonable first 
cut.  (Sorry, as I am currently 'out of contract' I am not going to 
volunteer to edit this document on this occasion, but I will do what I can to 
help.)

 

1)  An aim 
of the BPEL abstract process definition language is to enable the 
description of the allowed ordering of messages sent and received by a single 
party (/participant) to its immediate partners with a minimum of 
complexity.

 

2)  It should 
be possible to use an abstract BPEL process description as a step in the design 
process such as:

 

graphical 
description (BPMN or other) --> abstract BPEL process --> executable BPEL 
process (--> BPEL engine or code)

 

message sequence 
charts (/ state diagrams / charts) --> abstract BPEL process --> 
executable BPEL process (--> BPEL engine or code)

 

3)  It should 
be possible to use an abstract BPEL process description as a step in 'reverse 
engineering a process perhaps for the purpose of discussing with other 
parties while hiding certain details from those other parties.  For 
instance:

 

executable BPEL 
process (--> BPEL engine or code) --> abstract BPEL process -->  
graphical description (BPMN or other)

 

executable BPEL 
process (--> BPEL engine or code)--> abstract BPEL process --> message 
sequence charts (/ state diagrams / charts) 

 

'Requirement' 3) is 
obviously requires the ability to move in the reverse direction from that 
envisaged in 'requirement' 2).
