This is my proposal for a few extensions to BPMN to be able
to represent the choreography of collaborations. Here is an example (Process PO
collaboration).
The double line activity represent a business transaction
(we may want to use special symbols or lining scheme for indicating the need
for or lack of signals)
The dashed line represent the direction (initiating to

activity (e.g. Cancel) it means that both parties can initiate that
transaction.
Optionally, we can represent the message flow (
The little circle on each side of the BTA represent an
endpoint. The private process connects to these end points (not fully
represented here).
I had to create a new gateway which acts as both a fork and
a join. This means that change
It is start is agreeable, I will do a complete analysis of
what maps and does not map to a collaboration.
