Subject: Minutes of Atlantic UBL TC call 12 July 2006
MINUTES OF ATLANTIC UBL TC MEETING 15:00 - 17:00 UTC WEDNESDAY 12 JULY 2006 ATTENDANCE Jon Bosak (chair) Mavis Cournane Betty Harvey G. Ken Holman Alan Lemming Zarella Rendon Bryan Rasmussen Andy Schoka Paul Thorpe Sylvia Webb STANDING ITEMS Additions to the calendar: http://ibiblio.org/bosak/ubl/calendar.htm None. Review of Pacific call No comments on anything other than the items discussed below. Schedule review See Pacific TC minutes. JB: We're about a month behind schedule. Following the plan arrived at in the Pacific call will depend on resolving the issues in front of us today. MONTREAL UBL TC MEETING Register now! BH and ZR will be at Extreme but not the UBL TC meeting. NDR WORK SESSION Issue: ".0" in file names Discussion: Our previous omission of the minor version number from file names was based on problems that might be encountered by users hardwiring schemas into instances using xsi:schemaLocation. But binding an instance to a specific system-dependent schema file with xsi:schemaLocation is bad practice and creates portability problems. We cannot prevent users from engaging in bad practices, but we don't have to support them. Including ".0" in file names is not mandated by NDR VER12 but is certainly consonant with it. Note that this issue is unrelated to our use of XSD schemaLocation in UBL schemas. AGREED that we will use ".0" in file names (not namespace URIs). AGREED that in supporting materials, we will deprecate the use of xsi:schemaLocation in UBL instances and try to teach users how to accomplish entity resolution using XML Catalogs: http://www.oasis-open.org/committees/download.php/14810/xml-catalogs.pdf Issue: Location of the extension element Discussion: See the penultimate paragraph of http://lists.oasis-open.org/archives/ubl/200607/msg00008.html AGREED that ELD12 changes to: The 'UBL Extension' element MUST be declared as the first child of the document element with xsd:minOccurs="0". AGREED that ELD13 changes to: The 'UBLProfileID' element MUST be declared immediately following the 'UBL Extension' element with xsd:minOccurs="0". AGREED that ELD14 changes to: The 'UBLSubset' element MUST be declared immediately following the 'UBLProfileID' element with xsd:minOccurs="0". Issue: CCTS derivation of the extension element Discussion: The extension container is merely a syntactical artifact. It may contain information items with business semantics, but it has no business semantics itself. Since the extension element is not itself a business data item, it cannot derive from CCTS types. Similarly, since the extension element is not part of our data model, it cannot be specified in our spreadsheets. AGREED that MDC1 will be changed to read: UBL Libraries and Schemas MUST only use ebXML Core Component approved ccts:CoreComponentTypes, except in the case of extension, where the 'UBL Extension' element is used. Issue: Multiple extensions AGREED that (modulo syntax) one UBL instance may contain multiple extension constructs, each with its own set of metadata. We discussed GKH's proposed syntax: http://lists.oasis-open.org/archives/ubl/200607/msg00053.html AGREED that we will attempt to meet the schedule proposed in this week's Pacific TC call as follows, the objective being to submit PRD2 for approval as a Committee Draft next week: - GEFEG creates new schemas incorporating the NDR decisions noted above but not the extension element - GKH and BR discuss the proposed extension syntax (see URL above) via email with the objective of creating an appropriate schema fragment by Friday - The TC is notified that the syntax under discussion will be included in the upcoming PRD2 - The extension schema fragment is incorporated manually into the PRD2 schema set delivered by GEFEG - Release notes and announcements concerning PRD2 include a disclaimer to the effect that the schemas in their modified form are not supported by GEFEG ACTION ITEM REVIEW ACTION: PT to review the ASN.1 appendix the week of 10 July and provide any necessary revisions. Done. ACTION: NDR Editors to change ELD12, ELD13, and ELD14 to make it clear that the element declaration must exist and that the declaration will specify that minoccurs is zero. Done. ACTION: NDR Editors to modify ELD 12 as agreed. Done. ACTION: NDR Editors to review IND5, IND6, and ELD7 and modify them to except the UBL extension element. Done. Moved here from the Pacific TC call: ACTION: NDR editors to look at the syntax of the QDT for ChannelCode and tell TM whether this is a legal restriction under our NDRs. Pending. ACTION: JB to get new set of licenses from Altova. JB: Have sent the request. ACTION: PB to try to finish the resolution list Friday 9 June and send to the UBL list. Done. OTHER BUSINESS Next week's Pacific TC call AGREED that GKH will run the Pacific call if TM is unable to attend. Next week's Atlantic TC call The agenda will include NDR revisions to reflect the extension syntax included in PRD2. DKLSC SW: Will DKLSC replace NES? AL: No, DKLSC is for Danish translation; NES represents several government groups. Jon Bosak Chair, OASIS UBL TC
