Subject: Minutes of Atlantic UBL TC call 30 March 2005
MINUTES OF ATLANTIC UBL TC MEETING 16H00 - 18H00 UTC WEDNESDAY 30 MARCH 2005 ATTENDANCE Jon Bosak (chair) Tony Coates Stephen Green Mike Grimley Sue Probert Sylvia Webb STANDING ITEMS Additions to the calendar (http://ibiblio.org/bosak/ubl/calendar.htm) The UN/CEFACT Forum meets 26-30 September 2005 in Lyon. Liaison report: UN/CEFACT SueP: The Forum meeting in Kuala Lumpur was well attended. UNeDocs finally has a home in UN/CEFACT: a new TBG group, "TBG2, Digital Paper." The document-centric approach is now alive in CEFACT. Dick Raman has responded to our suggestion that the CEFACT NDRs be aligned with UBL with a proposal that would create "a single set of XML Schema NDRs that accommodate both global and local element declaration approaches through the creation of two normative schema for each data exchange. Users would have the option to use either schema, but since the NDR and schemas will be carefully crafted, the instance documents will be able to be validated against either approach." It remains to be seen whether this will work in practice. JonB: Even if it does work, I wonder whether this meets the need for a single standard set of schemas against which to develop cheap, off-the-shelf software. And it doesn't solve the problem created by having two completely different document-oriented XML syntaxes for UBL and UNeDocs. We need to discuss this further after we see whether the dual-NDR approach is technically feasible. We also need to start discussions with the team appointed by CEFACT. SueP: Given the large amount of overlap between the proposed UBL and CEFACT negotiating teams, Dick has suggested that we consider this a joint group tasked with working out a draft agreement to be agreed upon by the FMG and the UBL TC. [Thus the team would consist of Jon Bosak, Mark Crawford, Sue Probert, Tim McGrath, Michael Dill, Mike Doran, and Jean Kubler, with Crawford, Probert, and Dill representing both sides in this discussion.] ACTION: JonB to arrange an initial meeting of this team. ACTION: JonB to post Hangzhou meeting info. ACTION: JonB to request a specific time to report on UBL at the MoU/MG meeting in Brussels 4 April and post slides to the MoU/MG. Liaison report: TaX XML TC SylviaW: A small group has been reviewing UBL messages WRT tax requirements and has produced a list of about 30 data items that they feel are critical to an endorsement of UBL. They have also identified the need for some new document types -- credit note, debit note, quotation, quotation request, self-billed tax invoice, self-billed credit note -- and will submit these within the next two weeks for consideration in UBL 1.1. All the artifacts have been created in Edifix and are now undergoing review. JonB: This sounds similar to the requirements we're getting from OGC and IDA. Any connection? SylviaW: Nothing formal. JonB: So we will be getting two sets of similar requirements. SylviaW: Yes. W3C TAG TonyC: The subject of URNs came up and UBL was mentioned in passing as a URN user. Subcommittee report: SSC StephenG: The SSC has been discussing the derivation and import rules (8 and 9). We concluded that we can't keep to those rules; we've tried, and it doesn't work. In the end, we agreed on something close to the ATG2 alternative, and we'd like the NDR team to consider this revision for 1.1. The problem lies in the XSD syntax for extending things. There was also a lot of discussion of the changed NDR rules; there are a lot of questions to answer before we can produce 1.1 schemas. DavidK is working to produce a set of schemas from the 1.0 models that incorporates the uncontroversial changes. AGREED that we will attempt to stage a discussion of these issues over the next three weeks (i.e., in the Atlantic TC calls of 4/6, 4/13, and 4/20). JonB, MikeG, and StephenG are available for all three meetings; SylviaW is traveling 4/13 and 4/20 but will see if MichaelD or DavidK can attend; TonyC is OK with all except 4/13. We need to check with MarkC and MavisC to determine whether we'll have critical mass for this discussion. ACTION: TC to review StephenG's summary of current issues: http://lists.oasis-open.org/archives/ubl/200504/msg00003.html Subcommittee report: HISC and SBSC StephenG: The SBSC has produced a package that is being worked on now in the HISC (Beta 2). It needs a little editing; TimM will help with the prose. AGREED that we will first look at the package in the TC by mail, then circulate in lists like ebxml-dev for a wider public review ending in mid-May, then discuss the results in both the Atlantic and Pacific TC calls. ACTION: StephenG to post the package to the TC. ACTION: StephenG to be responsible for input back to Altova and other XML vendors interested in bundling the SBS with their products. ACTION: JonB to contact Altova to update them on our progress and get their requirements. ACTION: TC to review the current SBS package posed by StephenG. Team report: Code lists TonyC: We have added a lot of details to the CL proposal; the revised draft went out yesterday to the other team members for review. ACTION: TonyC to check the discussions that have been taking place in ubl-dev and xml-dev. Jon Bosak Chair, OASIS UBL TC
