Subject: Minutes of Atlantic UBL TC call 8 June 2005
MINUTES OF ATLANTIC UBL TC MEETING 15H00 - 17H00 UTC WEDNESDAY 8 JUNE 2005 ATTENDANCE Jon Bosak (chair) Mikkel Brun Mavis Cournane Stephen Green Mike Grimley Anne Hendry ADMINISTRIVIA Updated phone matrix (http://ibiblio.org/bosak/ubl/phones.sxc) We will skip the Atlantic meeting 6 July as well as the Pacific meeting 4|5 July. The Eurasia call 6 July will take place as usual [but we will call this a "work session" for attendance purposes -- see separate message to follow]. The NDR editors will skip their Monday call 13 June but will meet Wednesday 15 June before the Atlantic TC meeting. STANDING ITEMS Additions to the calendar (http://ibiblio.org/bosak/ubl/calendar.htm) None. Liaison reports None. Subcommittee reports No adds to reports in Pacific call. Team reports None. Review of Pacific and Europe/Asia calls MavisC: DTTN has agreed to review the Code List proposal. JonB: We will expect input from DTTN through ThomasL. MavisC: Also note that MikkelB has found a resource to look at the Customization guidelines. MikkelB: We think we'll have a proposal to review on the TC list in two weeks. ACTION ITEM REVIEW ACTION: JonB to review recent TC call attendance and change the status of members not attending 2/3 of the meetings from "voting" to "nonvoting." Status: Sent out notice last week and will update member status after today's meeting. ACTION: MikkelB to check to see whether PeterB can fill the position of UBL liaison to TBG17 and report back on this 8 June. MikkelB: PeterB is busy with other UBL work and will not be available for this. ACTION: JonB to ask for a volunteer to serve as liaison to TBG17. NDR WORK SESSION MavisC and MikeG had their first NDR editors call today and worked through a number of issues that were reviewed during the TC meeting. The following summarizes the documents currently in play and the decisions reached in the meeting. Changes to the NDR draft At the TC meeting in January, the NDR editors together with people attending the meeting worked through all the NDR issues outstanding at the time and incorporated them into a new NDR draft. The changes made then are documented in this change log: http://www.oasis-open.org/apps/org/workgroup/ubl/download.php/13007/ChangeLog%2006-06-05.txt The document that resulted from the changes made in January can be found here: http://www.oasis-open.org/apps/org/workgroup/ubl/download.php/12998/NDR-06-06-05.pdf AGREED that we accept the changes embodied in this January NDR draft unless we hear otherwise by the time of the Atlantic TC call next week. In their first work session today, the NDR editors made the changes recorded in the log at http://www.oasis-open.org/apps/org/workgroup/ubl/download.php/13005/ChangeLog%202005-06-08.TXT Summary of the changes: (1) Two NDRs (ELD2 and CDT2) have been modified to implement the decision to make all elements global. It appears unnecessary to make any changes to the surrounding language. (2) In section 3.1.2, a new rule, ELD10, has been added to address an issue raised by StephenG in his message dated 25 April 2005. We note that we may not yet have achieved complete agreement whether all elements in specific documents are suitable for Reusable, so this may have to be revisited further on. A revised draft of the NDR document that incorporates these latest changes can be found at http://www.oasis-open.org/apps/org/workgroup/ubl/download.php/13004/NDR-2005-06-08.pdf AGREED that while we may need to revisit the second item above at some time in the future, we will send the changes made so far to DavidK for implementation unless we hear an objection before next week's Atlantic TC call. (The idea here is to take advantage of DavidK's current availability so that we get in as many of the changes we seem to agree on as we can before he goes on vacation.) Code List review MikeG and MavisC reviewed the April Code List proposal and reported their findings as follows: - Skipped consideration of substitution groups and abstract types, as these have been identified as issues we need to discuss in July. Will review the xml-dev thread on this subject next week. - We need to look at the issue of namespace naming conventions for external code lists and make it explicit that we are not expecting our NDR rules for namespaces to apply to them. We may be adopting ATG2 code list schemas that are integrated with their data type schemas. - Comments on the Example code list document (1.5.7) [I couldn't relate MikeG's comments at this point to the line numbers in the file provided by MartyB as wd-ublclsc-codelistReqs-20050405a.doc -- hence the delay in preparing these minutes. After a couple of days of discussion, Mike and I still couldn't put this together; I suspect that we're seeing the effect of differences in the way that his environment and mine are set up to deal with the display of embedded comments and hyperlinks. I think we're going to have to make it a requirement that documents with line numbers be posted only in PDF so that we don't run into this problem again (I can generate the PDF from proprietary formats if necessary, and of course anyone using openoffice can generate PDF directly from the application). Mike kindly provided his comments by email; I reproduce them here in the hope that line numbers are close enough to enable Marty to relate the comments to the relevant passages in his copy: In section 1.5.7 'Example code list document' there is, as one might suspect, an example of a Code List schema: Comment 1 (Line 597)- On line two of the example is the namespace declaration 'xmlns:gcl="http://xml.genericode.org/2004/ns/CodeList/0.2/"'. This raised the question of whether we should explicitly state in the NDR that non-UBL code lists need not conform to our namespace naming conventions. Obviously, other agencies/organizations/companies may have their own conventions that must be adhered to. Comment 2 (Line 626) - Around Line 29 there is an element named "Value" which has an attribute named "ColumnRef" which conveys non-supplementary component information. This breaks rule [ATD1]. This also breaks rule [GNR4] which prohibits abbreviations/truncations (i.e. 'Ref' vice 'Reference') and rule [GNR9] which requires lowerCamelCase naming of attributes. In general, we need to decide which of our rules external code lists must comply with or, put another way, where Code Lists will be allowed as exceptions to the rule. (In this particular case, if the 'ColumnRef' attribute could be changed to a 'ColumnReference' element it would be fine.) Comment 3 (Line 651) - Around 25 lines after the previous comment target there is an 'AppInfo' section within the 'Annotation' section. It could just be a typo; however, just noting that it breaks rule [GXS12] In section 4.1 'Data Model Mapping': Comment 4 (Line 1040+) - Item 1. declares use of an 'Abstract' element. We should probably create a rule clarifying our stance on the xsd:abstract construct. It was mentioned on the call that this discussion will be tied to the 'Substitution Group' discussion(s).] AGREED that we will include a discussion of abstract elements and element types in our discussion of substitution groups. StephenG: Regarding supplementary components, a question for MartyB: Could the attribute ColumnRef on the Value element be implemented as an element instead? This would avoid breaking NDR ATD1. If not, we will have to make an exception for code lists. MavisG: Next steps for NDR team will be to get MarkC's input on the codelist stuff, then resolve the substitution group issue in July. We hope to have the results of the UBL/eDocs feasibility study by next week's call. Looks like we're on schedule. NEXT WEEK Sign off NDR changes noted above so that they can be transmitted to DavidK for implementation. Jon
