Subject: Minutes of Atlantic UBL TC call 20 April 2005
MINUTES OF ATLANTIC UBL TC MEETING 15H00 - 17H00 UTC WEDNESDAY 20 APRIL 2005 ATTENDANCE Jon Bosak (chair) Tony Coates Mavis Cournane Mark Crawford (vice chair) Stephen Green Mike Grimley Anne Hendry David Kruppke Paul Thorpe STANDING ITEMS Additions to the calendar (http://ibiblio.org/bosak/ubl/calendar.htm) None. Liaison reports None. Subcommittee report: SSC Has not been meeting while discussing [ver] and will not meet tomorrow. Subcommittee report: SBSC StephenG: Have just done another pass at index.htm and sent out to the SC, but this is not finished yet. It includes an example of BPSS referencing the SBS. JonB: Let me know when you want me to make another edit. Team report: ver StephenG: The team came up with two alternatives. (1) The default: redeclare everything in a new set of schemas and remove NDRs VER8 and VER9; or (2) move towards polymorphic processing support for both major and minor versions, which would require making everything global (thus allowing customizers to use the polymorphic approach even if we don't) and allowing a limited use of substitution groups in the construction of minor versions. The recommendation is to make the next version a major version with every element declared global; this wouldn't commit us to one method or the other. MarkC: See my mail to the list a couple of hours ago. The easiest thing is to make the next version 2.0, but this seems to abandon our goal of allowing pieces to be updated without requiring monolithic releases. Changing everything to global is not a problem. JonB: We could make it clear that only this release is monolithic, and that we're doing this to give us room to put in place a workable minor versioning strategy that we can live with going forward. MarkC: It would be good to align with ATG on the CCTS modules. MikeG: Agree with MarkC: don't want to lose the original intent of ModNamVer, but could do for this time if we make it clear that we do not intend to make monolithic releases the norm. It would allow us to align with the ATG schemas. AnneH: It's probably best to call this 2.0 and try to get in as many known backwards-incompatible changes as possible. DavidK: Think it's OK to go to 2.0 because there are some errors in 1.0 that would require such changes anyway. MavisC: OK with the second option. PaulT: No opinion. JonB: Should we say while we're working on it that the limited substitution-group approach is the one we're pursuing for minor revisions? MarkC: Still not convinced that there is no alternative to substitution groups, and we still need to deal with namespace versioning. Don't think we need to get rid of VER8 and VER9. In addition to global/local we would still need to discuss token [namespace prefix] versioning: NMS 8, 10, 12, 14, 16. Are we going to adopt the ATG schemas as they are, or are we going to publish them with modifications? AGREED: - We will call the next version UBL 2.0 - We will redeclare the whole schema set - We will explain that we are not adopting this monolithic approach as our strategy for versioning and that we still intend to produce a methodology for minor versions - We will make everything global (i.e., change ID and Code to global) - We will align with the ATG NDRs as far as possible, in particular with regard to the CCTS modules - We will continue work on a minor revision strategy, recognizing that we already have a workable proposed solution that we nevertheless need to discuss further Remaining issues for next round of NDR team work in Atlantic calls: - Whether namespaces change in minor versions - If so, how namespace prefixes are to be versioned - Whether we need to use substitution groups to effect minor versioning - What degree of backwards incompatibility we can tolerate - How today's decision affects NDR changes decided previously - Issues that still remain on the issues list AGREED: The Atlantic TC meetings of 5/18 and 5/25 will be devoted to deciding as many of these NDR issues as possible. AGREED: StephenG will wait on creating the list of schema changes for input to GEFEG until the beginning of June. TonyC: Members of the ver team should continue prototyping so that we can be crystal clear on the proposed solution. Need to look at counterexamples from MarkC. There may need to be content changes. [Didn't get this clearly -- Jon] SUMMER VACATIONS JonB: Reduced availability from beginning of July till our TC meeting in Ottawa. DavidK: Unavailable Second half of July. TonyC: Unavailable first three weeks of June. StephenG, MikeG, MavisC: Available all summer. PaulT: Unavailable first two weeks in July, last week of August, first week of September. JonB: We need to check on MarkC's schedule, but it looks like we can keep working on NDR issues over the summer even if I'm not able to chair. NOTE THAT THERE ARE NO MORE ATLANTIC TC CALLS TILL 18 MAY 2005. However, there will be several Pacific TC calls during that time, and work is expected to continue uninterrupted in the HISC and SBSC.
