Requirements on BPEL abstract process

["Tony Fletcher" <tony_fletcher@btopenworld.com>]

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).
