Subject: [ubl-ndrsc] Minutes for 10 April 2002 UBL NDR SC telecon
1. Roll call Bill Burcham YES (joined y:40) Mavis Cournane YES Mark Crawford YES Fabrice Desré John Dumay Matt Gertner YES Jessica Glace YES Arofan Gregory YES Phil Griffin Eduardo Gutentag YES Eve Maler YES Joe Moeller Sue Probert Ron Schuldt Lisa Seaburg YES Gunther Stuhec Paul Thorpe YES Quorum reached. New ACTION: Eve to talk to John Dumay, Sue Probert, Joe Moeller, Ron Schuldt to see if they want to drop their NDR memberships. Also talk to Gunther about rejoining the calls. 2. Acceptance of minutes of previous meetings 27 February 2002 telecon: http://lists.oasis-open.org/archives/ubl-ndrsc/200202/msg00091.html 6 March 2002 telecon: http://lists.oasis-open.org/archives/ubl-ndrsc/200203/msg00004.html 13 March 2002 telecon: http://lists.oasis-open.org/archives/ubl-ndrsc/200203/msg00014.html 18-22 March 2002 F2F meeting: http://lists.oasis-open.org/archives/ubl-ndrsc/200203/msg00028.html 3 April 2002 telecon: http://lists.oasis-open.org/archives/ubl-ndrsc/200204/msg00003.html Minutes accepted for all. 3. Adoption of agenda Agenda adopted. 4. NDR document production (led by Mavis): brief We agreed to various outline changes that would more accurately reflect the principle of factoring out common rules into a higher-level section. We agreed that the NDR document should be written as a "true spec", with crisp normative prose in the main text, and only references to appendices containing position papers that contain rationales for our decisions. So, for instance, the elements vs. attributes paper won't be incorporate as such into the text; it will be included as an appendix. We agreed that we should include examples wherever possible, but to say in the preface that examples are non-normative. We deferred a decision on whether to include context methodology information directly into the NDR document. One thing is certain: The context methodology shouldn't be a bottleneck for NDR. Mavis will continue to edit the draft and will talk to individual position paper authors before incorporating text from them. New ACTION: Eve to help Mavis with applying an "OASIS Word template" to the NDR document. 5. RT/CCT discussion: 20 min See the thread starting at: http://lists.oasis-open.org/archives/ubl-ndrsc/200204/msg00005.html We need a way of describing the semantic function of a piece of information (RT), and then we need a path to the structure that provides clusters of properties (CCT). The relationship is not one-to-one, and thus we need the ability for each XML construct to have an assignment to both. E.g., an element can be assigned an XSD type corresponding to a CCT, and it can have a fixed attribute corresponding to an RT (or its dictionary entry can merely reflect this information). Right now, the relationship between RTs and CCTs is nominally many-to-one, but there are certain ways in which this breaks down in practice. The proposal would make it many-to-many. (The problem of capturing precision information sounds like it may be a "hole" in the original CCTS analysis, so maybe it's not specific to our work.) If we really go in this direction, then the LC SC is likely to need to identify an additional piece of information, in addition to the RT, for each of their rows. New ACTION: Arofan to attempt a more specific proposal along these lines. 6. Filling in the tag structure holes (led by Mavis): 20 min See the latest position paper at: http://www.oasis-open.org/committees/ubl/ndrsc/pos/draft-arofan-tagspec-03.doc We reviewed these, but didn't decide any. New ACTION: Mavis to post each of the "live" issues to the NDR list separately for email discussion. 7. Action items and prioritizing our next chunk of work: brief Summary of work to be done (revised during this call): A External recommendations for changes to CCTS A Code lists A Modnamver A NDR document production A Review the purchase order schema design **A Officially decide elements vs. attributes and empty elements B Tag structure B Containership B Fixed vs. varying types C Dates and times Schedule (revised during this call): **April 17: Code lists, tag structure, RT/CCT comments, elem vs. att (2hr) April 24: (1hr) May 1: (2hr) May 8: (1hr) May 15: (2hr) May 22: (1hr) May 29: (what else?), approve NDR document for distribution (2hr) June 5-9 (the F2F meeting itself, if all goes according to plan) Current ACTION items (not reviewed explicitly during the call): Everyone: - A: Review the modnamver paper, the examples, and the 0.64 schema distribution. - A: Read Matt's types paper by 10 April and see if we want to prioritize it higher.
