RE: Thanks to all and next steps

Joseph and all,

I think we are getting hung-up on this topic of “invoice” again … may I offer:

 

V1 = we are NOT seeking to include a standard for invoice nor contents related to such. We COULD offer an optional call to include an invoice of a format used by both payee and payer should that be of interest in the implementation (highly likely to loyalty processing). However, we WOULD like to include a <signal of some kind> that the payment has been sent for processing as feedback to the payer/customer. The payee/merchant uses that (or other means NOT in this process flow) to effect fulfillment and other activities which occur around the timing of the payment. Please note from the F2F – the payment may be held from settlement until fulfillment is accomplished (in the case of physical goods) to accommodate standards (and some regulation) about when the payment may be accepted by the merchant.

 

While I am a very big proponent of the use of “invoice” and “itemized receipts” – there are far too many standards and de facto standards to enable through a single payment flow. It would restrict the communications between buyer/seller and force too much compliance. The idea is that the feedback to the payer makes sense that the payment transaction has been “accepted” or is “in progress” – whatever term might be useful and productive here. It is not useful to “invoice” unless that is truly part of the process flow between buyer/seller.

 

I would like to reiterate my support for a  <signal of some type> to the payer that the transaction did, in fact, get submitted – better yet that it was “completed” to end the payments transaction. I agree with the strong opinions that the “invoice” or “receipt” are not the intention of the payments process.

Thanks Adrian,

RE: "no longer intend on defining either an electronic invoice or receipt but simply a payment request/response and confirmation"

Based upon what Manu referred to as "the final list of use cases for version 1" (dated 20 June): 
https://www.w3.org/Payments/IG/wiki/Main_Page/FTF_June2015/UseCasesForVersion1
...three of the use cases in the current selection, from the "Agreement on Terms" part, are each pre-payment functions involved in e-invoice development:

HYPERLINK "http://www.w3.org/TR/2015/WD-web-payments-use-cases-20150416/#agreement-on-terms"Registration-less (Agreement on Terms) 
HYPERLINK "http://www.w3.org/TR/2015/WD-web-payments-use-cases-20150416/#agreement-on-terms"One Time Payment (Agreement on Terms) 
HYPERLINK "http://www.w3.org/TR/2015/WD-web-payments-use-cases-20150416/#agreement-on-terms"Subscription (Agreement on Terms)

It seems to me that in the sequence: Payer/Payee >> Invoice >> Wallet/Account >> Payment System

1. Buyers & Sellers: W3C has a mandate to specify essential commonalities in how all browsers should handle any [Payer/Payee >> Invoice] sequence. This work should take-as-given any e-invoice documents and components established and maintained by the authoritative e-Commerce semantic and technical specifications. The most prominent of these is UBL, which can be expressed in XML or JSON;

General Architectural Requirements:
• United Nations Commission on International Trade Law (UNCITRAL): “Model Law on Electronic Commerce”; “Model Law on Electronic Signatures” and related UNCITRAL guidance http://www.uncitral.org/uncitral/en/uncitral_texts/electronic_commerce.html
• International Institute for the Unification of Private Law (UNIDROIT): “Principles of International Commercial Contracts”. http://www.unidroit.org/publications/513-unidroit-principles-of-international-commercial-contracts


2. Financial Services:  W3C has a mandate to specify how any Wallet/Account and how any Payment System should accommodate any Web-originating/terminating [Invoice >> Wallet/Account >> Payment System] sequence. This work should take-as-given any financial messaging requirements and types established and maintainted by financial messaging specifications. The most prominent of these is UNIFI (better known as ISO 20022) which can be expressed in XML or JSON.

General Architectural Requirements:
• Bank for International Settlements: “Principles for Financial Market Infrastructures”
https://www.bis.org/cpmi/publ/d101.htm?
• International Organization of Securities Commissions (IOSCO): “Objectives and Principles of Securities Regulation” 
https://www.iosco.org/about/?subsection=key_regulatory_standards

In the above, I use the word "Requirements" deliberately because even though their respective elements are only guidelines, neglect of any  of their elements is sure to cause lasting headaches.  (I accept that the challenge of trying to accommodating all those elements up front is itself quite a headache, but it's the short-term-pain-for-long-term-gain variety.)

Hi Joseph,

To add some clarity. The work we did at the face to face was mostly to narrow the scope of v1 to explicitly exclude anything not required to execute a payment. You'll notice that we no longer intend on defining either an electronic invoice or receipt but simply a payment request/response and confirmation.

My feeling was that this was due to the acceptance by all that a lot of this is outside the scope of "payments" and more in the scope of "commerce" and therefor necessarily introduces the need to incorporate work from a far wider scope of liaison bodies.

My perception of the v1 scope is to define standard messaging and a protocol to initiate and complete payments from the browser while leaving the bulk of the specifics to the payment scheme that is used. v2 of the group's work will be wider in scope and will be based around the liaison work done by the external reviews task force.

It seems to me critically time-sensitive that the IG's specifications boundary (in scope / out of scope) be rendered operational in terms of defining and engaging working relationships with other primary entities that hold the official mandate for (a) Payment Systems Principles (eg BIS, UNIDROIT); (b) e-Commerce Model Laws (eg UNCITRAL); and (c) Payment Information Specifications (eg ISO-TCs; OASIS-TCs). 

The IG's official reply to the X9 review states: "As you rightly observe, several aspects of what we are working on (e.g., trust, credentials, digital signatures, loyalty programs, etc.) extend beyond a payment transaction and are applicable to other standards efforts that may not even involve payments."  

Several matters being worked on by this IG also extend beyond the W3C's specifications domain. 

It is not clear why a "hot front-burner" process is not established for this.

Thanks to everyone that attended and participated in the 2015 W3C Web
Payments face-to-face in NYC. I was particularly thrilled during the
roundtable as the message the group members were delivering demonstrated
an aligned vision. What's more impressive is the people that are
participating and the short time that it took to put this new effort
together and align our direction.

There's still much more work to do, but my confidence that we can pull
this Web Payments stuff off is the highest it has ever been.

I was just reviewing the goals of the meeting and had a few thoughts for
the coming weeks:

> Prioritize payments use cases and the capabilities necessary to
> fulfill them.

We came out of the face-to-face with a solid list of use cases:

https://www.w3.org/Payments/IG/wiki/Main_Page/FTF_June2015/UseCasesForVersion1

I don't think we identified all the capabilities needed for V1, but with
a well-defined list of use cases, I think we'll be able to do a good job
with the capabilities over the next several weeks.

I'm going to go through the use cases and update all the V1 use cases
with the clarifications made throughout the face-to-face meetings. I'll
also list the use cases in the Roadmap document.

> Review draft charter(s) and plan for first round of standardization

Quite a bit of work went into the Payment Architecture WG charter and I
think we have enough feedback to draw up a draft charter that can get
consensus from the group via the mailing list.

I don't think we can say the same for the Authentication WG charters or
the Credentials WG charter.

Next steps for the PAWG charter seem to be for Ian to revise it and pass
it by the group.

Next steps for the Authentication WG charters seem to be for us to
identify capabilities that we can put into those charters.

Next steps for the Credentials WG charter seems to be to coordinate w/
the Credentials CG and try to get more support from outside of this group.

> Initiate discussion on other IG activities (to follow push towards

I don't think we really spent too much time discussing this, other than
"focus on V2, external liaisons, and supporting the WGs".

Next steps may be to back burner this until after the PAWG is launched.

> Solicit feedback from broader community on group's direction (via
> the roundtable)

The feedback that we heard during the roundtable was probably best
summarized by what was not said; there didn't seem to be an objection
for the current direction. There were concerns over privacy and level
playing field. The cocktail reception discussions didn't reveal (to me)
any concerns about the current scope of work around payments.

The biggest criticism seemed to be a lack of near-term focus on identity
and credentials, but that may be my bias kicking in.

Next steps would probably be to establish deeper connections with the
Roundtable attendees and ensure that they're involved in future reviews.

All in all, I think we made excellent progress. Thank you for all the
great comments, input, and discussion.
