Subject: Re: PIP IDs

Up to now, RosettaNet PIPs are either request-response (two-actions) or notification (one-action) style business processes. Earlier versions of PIP 3A4 are an exception in the sense that PIP 3A4 covers Create Purchase Order (request-response), Change Purchase Order (request-response) and Cancel Purchase Order (request-response) interactions. Recently, PIP 3A4 has been split into 3A4 (Create Purchase Order), 3A8 (Change Purchase Order), and 3A9 (Cancel Purchase Order) in order to achieve some degree of uniformity across PIPs (I believe). Therefore, I think it is reasonable to equate existing RosettaNet PIPs with BPSS Business Transactions.
In the RosettaNet message header, there are separate elements to identify the PIP ID, the PIP action and the Service. Multiple PIPs may be implemented by the same service, e.g., there may be a Buyer service implementing PIPs 3A4, 3A8, 3A9 from the buyer perspective, and a Seller service implementing the same PIPs from the seller perspective.
I don't think we should equate PIP ID with Service and action with "the particular business transaction within the PIP". Otherwise, we will not be able to capture the role information, e.g., the ability to distinguish a Buyer Service from a Seller Service, and a request action from a response action.
From the RosettaNet point of view, it will be desirable if we can have distinct Service, PIP (equivalently BPSS Business Transaction), and action elements in the message header. Alternatively, we can use the Service element to capture role information (e.g., Buyer vs Seller), and use the Action element to capture the PIP ID. Whether we are dealing with a request action or a response action will have to be inferred from the Service element.

Subject: Re: PIP IDs

In my opinion it makes more sense for Service to point to the PIP ID and
action to point to the particular business transaction within the PIP. In
other words one execution of a PIP is a conversation.  I believe that some
of the PIPs include multiple business transactions.

Subject:  PIP IDs

David, in the F2F you mentioned the need for a new element to contain
industry specific business process identifiers such as a RosettaNet PIP
identifier. Could this be done with Service/Action where the Service would
be something like RNet and the Action something like PIP3A1 (Request
