RE: [payment agent] Transaction phase-based proposal

Hello Manu,

Things are starting to converge as I hoped they would. I added a few - very rough - flows, as promised. We used a user's/ clerk's view in here and these pics should fit well with your document.

Let's, thus, talk about these as well and see to align them in vocabulary and semantics today.

Cheers,

 Jörg

Subject: [payment agent] Transaction phase-based proposal

Hi all,

Before the holiday break, I promised a more complete example of what a transaction phase-based approach might look like for the payment agent document. Here's a rough cut of that example:

https://docs.google.com/document/d/1q_1OA1FPE1L-jkXlvu89RFSJ3FGWeHyw5SUJotfiACk/edit


The section to pay attention to is "Phase 3: Payment Instrument Negotiation / Payment Request":

https://docs.google.com/document/d/1q_1OA1FPE1L-jkXlvu89RFSJ3FGWeHyw5SUJotfiACk/edit#heading=h.azz2z0d14zgh


It starts by providing an overview of the expected flow (via a simple swimlane diagram). It then points to the use cases in the use case document that apply to this particular phase of the transaction flow.
The section then points out the specific features of the Payment Agent that come into play in this phase and when they come into play. Then it closes by providing a detailed explanation of the swimlane diagram flow, elaborating on any notable things that happen in the process.

Also note the Payment Agent section here:

https://docs.google.com/document/d/1q_1OA1FPE1L-jkXlvu89RFSJ3FGWeHyw5SUJotfiACk/edit#heading=h.fz60236fv1sw


I'd expect that this is where the diagram that Pat has been working on would go. That, or maybe we save that diagram until the end (we may want the beginning of the document to be a gentle introduction with a more high-level block diagram that's representative of Pat's more detailed diagram?).

Food for thought for the call tomorrow.
