TC Vitality check

 

As described in the new TC Process (https://www.oasis-open.org/policies-guidelines/tc-process-2017-05-26/#tcVitality), we need to perform a vitality check every 4 years and decide one of the following actions:

 

-  Continue the TC with its current charter;

-  Continue the TC through a charter clarification;

-  Recharter the TC; or

-  Close the TC.

 

At the same time, the TC must appoint or reappoint chair(s).

 

Charter clarification

 

A ballot to approve the clarified charter is open and closes January 22: https://www.oasis-open.org/apps/org/workgroup/bdxr/ballot.php?id=3554

 

Appointment of chair(s)

 

Kenneth was only candidate after the call for candidate for TC chair. Are there any objections to reappointing Kenneth as TC chair?

 

No objections at the neither Pacific nor Atlantic calls.

 

Next time the TC has to appoint or reappoint TC chair(s) will be January 2023.

 

SMP 2.0

 

A ballot for continuing with the Call for Consent for SMP 2.0 as an OASIS Standard is open and closes January 22: https://www.oasis-open.org/apps/org/workgroup/bdxr/ballot.php?id=3555

Kenneth made the motions. Seconded by Ken. Approved by all members at the Pacific and Atlantic calls.

 

AS4 profile for four-corner networks

 

Discussions within the BPC revealed the need for a transport layer validation and response when the receiving access point (corner 3) cannot receive a message on behalf of or determine the identity of the final recipient (corner 4). The CEF AS4 profile has defined AS4 properties for carrying information about the final recipient within the ebMS message, which can be used for validation and for rejecting a message in the initial communication with the sending AP (corner 2).

 

Would it be desirable to create a generic AS4 profile for 4-corner networks, either a committee note or a specification? Agreed at the 20/10 call that the TC wants to work on this. Todd volunteered as lead-editor with co-editing support of Dennis, Sander, Philip and Kenneth.

 

Agreed at the project meeting November 17, 2020 to write a Committee Specification. Drafting of CS is in process.

 

Starter template provided here: https://lists.oasis-open.org/archives/bdxr/202012/msg00014.html

 

Next project meeting will be held January 26.

 

Overview of the four-corner model Committee Note

 

During work with BDXL 1.1, Sander and Kenneth identified that elements of the text (describing the four-corner model, its components and its actors) would perhaps be better suited for a broader Committee Note. Template has been provided here:

 

https://lists.oasis-open.org/archives/bdxr/202101/msg00026.html

 

BDXL

 

BDXL 1.0

 

A ticket was created pointing out an issue with regular expressions in the BDXL 1.0 examples. It was agreed at the TC meeting November 25 to focus on BDXL 1.1 first, and then look at a possible BDXL 1.0 errata after that.

BDXL administration API

 

Proposal from Erlend: https://lists.oasis-open.org/archives/bdxr/201905/msg00015.html

 

There have been discussions within Peppol regarding requirements for the BDXL Administration API. Sander will reach out to the involved participants to gather further requirements.

 

Agreed that the updated BDXL 1.1 specification will mention the BDXL Administration API and its features for updating and maintaining BDXL records.

 

Discussed that the BDXL Administration API could include a section for how to update a primary BDXL in a federated model.

 

Steps forward:

1)    Map the API interface from the existing specification previously submitted to the TC (Kenneth)

2)    Describing functionality (group)

3)    Work on XML and JSON bindings (Sander, Dennis and Kenneth)

 

Kenneth presented a map of the Peppol SML registration interface as well as a class diagram showing the data model. It was discussed that the data model for the BDXL administration API may need to be developed in parallel to the API if special functions such as batch updating (“grouping” participants with services) need to be supported. Diagrams used for discussions: https://lists.oasis-open.org/archives/bdxr/202007/msg00017.html.

 

Discussed whether NAPTR records other than “U”-flag records are allowed in BDXL 1.0, and whether redirect type NAPTR records can be used as a strategy. Agreed that we need to advance further with the updated BDXL specification before moving forward with the API. It was agreed at the August 12 TC meeting that the introductory sentence in section 2.2 (normative), which states that “Because the goal is to find URLs, the NAPTR RR with “U” value in its Flags field (U-NAPTR)” narrows the scope of U-NAPTR records in the specification to those with “U”-flags, and that “U-NAPTR” elsewhere in the specification consequently refers to only those NAPTR records with “U”-flags.

 

BDXL 1.1

 

Starter document received from OASIS: https://lists.oasis-open.org/archives/bdxr/202002/msg00015.html

 

Discussed that the hostname to look up the NAPTR record (commonly done as “BASE32([SHA256 hash of participant ID])” and “B-[MD5 hash of participant ID]”) should be standardized.

 

Federated BDXL

 

Agreed to add a section about BDXL network federation to BDXL 1.1. Both Peppol and the Business Payment Coalition are working towards federated BDXL designs.

 

BPC rationale is to create competition among several BDXL service providers, allowing network participants to freely choose among available services. All BDXL services will offer similar and compatible services.

Requirements: https://lists.oasis-open.org/archives/bdxr/202006/msg00003.html

 

Peppol is looking at delegating control of different participant identifier schemes to different SML services, as well as possibly separating groups of participants based on their ID. There would be an algorithm that enables APs to locate the appropriate SML service based on the calculation of the participant identifier. Part of the rationale is that the transactional footprint on the current SML has increased with the addition of DNSSEC, and grouping participants into different SML services is a strategy for distributing the load.

 

Discussion paper for multiple registration services with only one DNS provider: https://lists.oasis-open.org/archives/bdxr/202006/msg00003.html

 

Discussed that in DNS, zone changes are replicated from primary DNS to secondary DNS services through zone transfers and that the update of primary DNS services can be done using DNS Update: https://tools.ietf.org/html/rfc2136

 

Sander and Kenneth had a meeting to come up with a proposal for an architectural drawing of a federated BDXL model within the complete 4-corner network. The outcome is shared here: https://lists.oasis-open.org/archives/bdxr/202007/msg00010.html

 

Discussed that the BDXL specification could/should hold information about the current registrar service of a given participant, so that BDXL and registrar services can prevent unauthorized updates of participant identifiers registered through a different registrar service.

 

Discussed to include a non-normative section describing different network policies and approached to KYC and participant registration.

 

Kenneth will begin drafting an introduction for BDXL 1.1.

 

TC conference call schedule

 

Agreed to hold weekly meetings until further notice.

 

Face-to-face meeting

Should we schedule online work sessions to replace the face-to-face meeting?
