Subject: Minutes of BDXR TC face-to-face meeting 18-20 September 2012


MEETING MINUTES OF BDXR TC FACE-TO-FACE MEETING 18-20 SEPTEMBER 2012

DAY 1
ATTENDANCE
Roger Bass (via conference call)
Kenneth Bengtsson (chair)
Pim van der Eijk
Sander Fieten
Giorgia Lodi (via conference call)
Dale Moberg
Alfio Raia (via conference call)
Sven Rasmussen
Ferdinand Rödlich (guest, UN/CEFACT Forum)
Thorkild B. Westergaard (guest, UN/CEFACT Forum)
Susanne Wigard

SUMMARY
The meeting commenced at 10.30. The chair welcomed the participants and informed that the meeting was conducted under OASIS IPR policy.

Item 1: Architecture, governance and trust
The group reviewed the 4-corner model where two entities exchange business documents through the use of gateways, and the agreed architecture where the gateways make use of a DNS-based discovery to locate a metadata service of the recipient gateway.

Kenneth explained the governance and trust model used by PEPPOL. In this model, operators of network gateways forms a community with a formal multilateral community agreement between them. The community agreement governs how network gateways exchange documents within the community and also sets standards for how the network gateways must behave on behalf of their users, but it is up to the individual network gateway operator to decide how to interact with his users.

Susanne and Ferdinand explained the governance and trust model used by e-CODEX. In e-CODEX there is a similar “community” agreement between network gateway operators (referred to as the “circle of trust”) as in PEPPOL, and the governance models are essentially identical.

It was agreed that Kenneth writes a document describing the architecture, governance and trust model to be used as a straw man for further discussions. This document should contain example agreements from PEPPOL and e-CODEX or highlights from these.

Item 2: e-CODEX complex routing
Susanne and Ferdinand explained the complex routing scenario of e-CODEX, in which specific parameters decide who is the final recipient of a business document. It was clarified that the complex routing scenario of e-CODEX is not so much part of the document exchange itself, but is to determine who the recipient of the document is before it is sent. It is essentially a rules based directory.

It was agreed that the complex routing scenario is very specific to e-CODEX and will probably not find use in other contexts.

The meeting was adjourned at 17.45.

DAY 2
ATTENDANCE
Roger Bass (via conference call)
Kenneth Bengtsson (chair)
Andrea Caccia
Pim van der Eijk
Sander Fieten
Giorgia Lodi (via conference call)
Dale Moberg
Alfio Raia (via conference call)
Sven Rasmussen
Ferdinand Rödlich (guest, UN/CEFACT Forum)
Thorkild B. Westergaard (guest, UN/CEFACT Forum)
Susanne Wigard

SUMMARY
Item 1: Joint Trusted Exchange of Trade Documents workshop with UN/CEFACT
UN/CEFACT organized a workshop to discuss a new project to establish a UN recommendation for Trusted Exchange of Trade Documents. BDXR is specifically mentioned in the UN/CEFACT project proposal. No further work seems to be needed by the TC, and Kenneth will keep the TC informed about eventual developments in the UN/CEFACT project.

Item 2: Service discovery and DNS
The TC meeting commenced at 14.00 and the chair informed participants that the meeting was conducted under OASIS IPR policy.

Dale presented his ideas and visions for DNS based “metadata service location discovery”. As previously discussed at TC conference calls, Dale’s model offers various mechanisms to resolve the location of metadata services by use of existing DNS specifications and technologies. It was discussed that a URN party identification registry will need to be administered by an organization that is capable of governing such registry, and ISO was mentioned as a plausible candidate.

It was agreed as next step that Dale finishes the draft specification to be discussed by the TC.

The meeting was adjourned at 18.00.

DAY 3
ATTENDANCE
Roger Bass (via conference call)
Kenneth Bengtsson (chair)
Pim van der Eijk
Sander Fieten
Martin Forsberg (observer)
Dale Moberg
Sven Rasmussen

SUMMARY
The meeting commenced at 09.00 and the chair informed participants that the meeting was conducted under OASIS IPR policy.

Item 1: Connect protocol and metadata formats
Pim presented the initial idea of a “Connect” protocol allowing parties establish a connection for exchanging business documents in an open (ungoverned) network. A process flow for the Connect protocol was drawn up and discussed. It was generally agreed that a Connect protocol would have an important function in an open network where network gateway operators do not have mutual agreements governing business document exchange between them (opposite the community/circle of trust governance model). It was also observed that many of the proposed functionalities of the Connect protocol would have use inside a governed network.

It was agreed that the TC works on specifications for the Connect protocol. Sander will work with Roger on starting a document with a general description and the process flow. 

Item 2: Action items
The following action items were agreed:

* Kenneth to produce a straw man / discussion paper on architecture, community governance, and trust within a governed network. To be finished within the next two weeks
* Dale to produce a first draft of specifications for metadata service location discovery. To be finished within the next two weeks.
* Sander and Roger to produce document describing in general the Connect protocol and the process flow when two parties use the Connect protocol to exchange business documents. To be finished within the next 4 weeks.

Item 3: Any other business
Dale observed that there might be a business need for an end-to-end tunneling profile. There was a broad discussion of the applicability of end-to-end protocols within a 4-corner model. It was agreed that Dale further investigates market demand for this, and that the TC is open to publish the specifications for such profile if a market demand exists.

There was no other business and the meeting was adjourned at 16.30.

Kenneth Bengtsson
