Draft minutes of the UBL face-to-face in Zwolle, October 1-5, 2018

["G. Ken Holman" <gkholman@CraneSoftwrights.com>]

(I apologize to committee members and to other followers of the technical
committee that I am so very late in posting these minutes, but I have been
on the road constantly since the meeting ended, waving the UBL flag at a
three-day conference in Berlin and in three lectures and one workshop in
Helsinki, (recruiting for the committee at the same time) and only now am
I getting through all of my action items that have been on hold . . . Ken)

Production of materials
 - Kees has generously volunteered to take over document and artefact
   production
 - agreed that Kees is a co-editor of UBL 2.3

OASIS
 - new logo and colours
 - Ken has posted latest stylesheets with the new look-and-feel
   - http://docs.oasis-open.org/templates/DocBook/spec-0.8

Pre-award
 - Europe is focusing on public procurement and the benefits achieved
   by digitalizing the procurement domain
 - while UBL does include (optional) European specializations, it is
   thought that the semantics are generic enough to be used elsewhere,
   but this hasn't been tested yet
 - Norway is working in a "playground" of new documents that will be
   taken to UBL once they have been exercised and proven

Post-award
 - a review of the use of post-award documents

Transportation
 - attendance in the subcommittee has been low
 - start looking at food certificates and certificates in general
 - need to be able to request a certificate and have one returned
 - also will look at: ATA Carnet, export declarations
 - it was noted that the http://eimpactproject.eu project has ended
 - perhaps we can find new participants from e-Impact participants
 - Ken observed that there are a lot of logistics-related blockchain
   projects that should be looking at UBL for interoperability
 - Peter trying to start a pilot project to set up transport bookings,
   letters of credit, and certificate of origin (starting with a three-
   corner model and moving to a four-corner model)

Payments and finance
 - Kenneth working on documents of trade finance
 - Todd looking at payments side and the harmonization of UBL with 20022
 - ISO 20022 committee asked by European banks to embed UBL in PAIN messages
 - subcommittee will perform a gap analysis between UBL and 20022
 - considered that the letter of credit will be under PayFin purview to help
   the transportation group

Small business
 - need for interoperability between different vendors of accounting tools
 - making UBL accessible to promote e-invoicing for small business
 - huge opportunity for adoption of UBL
 - problem with the magnitude of UBL
 - problem with perception of the importation of data from interchanged
   messages
 - staged implementation approach with a small set of documents for a small
   set of use cases, not a UBL subset per se
 - Matt to review the charter to reflect new understanding of direction

Pre-award ticket review and discussion (results captured in JIRA)

Discussion re: semantic RDF serialization of UBL content
 - creating an ontology of UBL by adding a couple of columns of axioms
   to the spreadsheets
 - would we need a phased approach of different business areas?
 - UBL is disadvantaged in the eyes of new developers focused on semantics
 - consider do we need an RDF serialization from the CCTS?
   - if so, we would first need a new chapter of the UBL NDRs
 - discussion is tabled for now, but please consider what options there may be

NDR
 - discussion regarding adding an extension point at every ABIE
   - cons
     - becomes too easy to add a bad extension where UBL could have been used
     - threshold for using extensions is lower
   - pros
     - extensions are contextualized without needing elaborate pointers
       - e.g. easily drop in foreign vocabularies at any construct
     - threshold for using extensions is lower
     - good feedback from Martin regarding practical testing of the feature:
       https://lists.oasis-open.org/archives/ubl/201808/msg00018.html
 - agreed to implement the new approach in the first working drafts to get
   feedback from the review community

Transportation
 - Trade Certificate (in general, or for food)
   - a detailed modeling exercise has produced a candidate starting document
     with new library ABIEs, ASBIEs, and BBIEs
 - Item
   - need to change cardinality of OriginCountry from 0..1 to 0..n
 - Letters of Credit
   - after a detailed analysis, it was decided that the two existing ISO 20022
     messages tsrv.001.001.01 UndertakingIssuance and tsrv.002.001.01
     UndertakingIssuanceAdvice likely suit the requirement sufficiently not
     to need to create a document in UBL, though this will be analyzed

Artefacts and documentation methodology and content
 - started on Thursday with the generation of 
schemas using the tools on Github
 - to be continued on Friday

Trade certificate
 - review of the target use of certificates for food, animals, etc.
 - completed first draft of semantic components
 - Peter to create a spreadsheet for the new document

Appreciation
 - the group expressed their greatest appreciation to Kees for his hosting
   of the face-to-face and to Wehkamp for the generous use of the facilities
