Review of Pacific call AGREED that BH will send updated spreadsheets, including a final set of comments about catalogues, to SW for inclusion in the categorized spreadsheets. ACTION: JB to check with C. Michael Sperberg-McQueen and Murray Maloney regarding possible contacts at McGill. SBS BALLOT JB/SG: Balloting has started on UBL 1.0 SBS CS. BRUSSELS UBL TC MEETING JB: Note IDABC as co-host (Emilio.CASTRILLEJO@cec.eu.int). PB: Checked via email to hotel about room for 5/25; will follow up. MC: Note special weekend rate of 60 euros per person at the Argus Fri/Sat/Sun. ACTION ITEM REVIEW ACTION: JB to check with Professor Kim regarding attendance in Brussels. Pending. ACTION: JB to enter a couple of issues not belonging to any SC. Done. ACTION: PB to check out facilities for our May meeting in Brussels on his visit to CEN/CENELEC 11 April. Pending. ACTION: PB to look at the NDR and say whether a change is needed [for the extension proposal]. Done. JB: Other NDR issues? PB: Version is covered by ABIE instead of attribute, and that's OK. But we have a requirement from uk/se/dk for a place to indicate which application generated an instance for debugging purposes. We were told in Ottawa to use a PI. GKH says we shouldn't formalize a PI into a standard, but this is an instruction for processors. JB: There doesn't seem to be another good way to do this. MG: This is an instance thing; it doesn't affect validation. The instance would still be a valid UBL document even if we didn't specify the PI in the NDRs. I think this is OK between two trading partners. If we're going to address this, it should be in "best practices" -- something non-normative. AGREED that we don't need to address this in the NDRs. JB: We can visit this again after November when we get to best practices. NDR WORK SESSION Extension proposal: http://lists.oasis-open.org/archives/ubl/200604/msg00013.html MG: No objection. MC: Comfortable with this because the extensions live in their own namespace. TC: In MDDL, people do want to use the original elements [in extensions] to make it clear where they are doing the same thing. We originally prohibited this and then recanted. The extensions are wrapped in a special element... JB/BR: This is what's being suggested for UBL. TC: We should allow the UBL children directly in the special element; it's the element that tells you that you have the extension. All: We're not sure why GKH wanted a non-UBL layer between the extension element and the UBL children. JB: In mail off the list, he said: What this means is that we can, in XSD, express "child elements in any non-UBL namespace" and have it throw an error if one of those children is in UBL. Note that descendants below children may be in the UBL namespace ... this will allow an extension writer to take advantage of UBL, but still require them to wrap their extension use of UBL in one of their extension elements. I'm hoping I'll be able to "say" this in NVDL. All: We could use more discussion on this point in email. AGREED that the document extension area should go at a high level, but last in the schema. ACTION: PB and BR to submit a more detailed proposal along these lines, possibly contacting MG offline; for submission week after next at the latest. (Next week is the Easter holiday in Europe.) MG: What of GKH's thought about extending Party? BR: In dk practice it turned out that people just wanted to extend the document. AGREED that we will just specify extension at the document level in the 2.0 cycle and then take up the question of extending other pieces in future versions. OTHER BUSINESS Not on the call next week: BR, PB, MC. Jon Bosak Chair, OASIS UBL TC
