[ubl] Fwd: [ubl-ndrsc] Minutes for 28 November 2001 UBL NDR meeting

["Eve L. Maler" <eve.maler@sun.com>]

Here are the minutes from today's Naming and Design Rules SC meeting.  We 
are driving towards having a useful snapshot of our work ready for Jon's 
presentation at XML 2001, and next week we will identify key schema support 
issues that he can tell vendors about.

>
>    7 November 2001 meeting:
>    http://lists.oasis-open.org/archives/ubl-ndrsc/200111/msg00026.html
>    Accepted.

>    Accepted.

>    Accepted.
>
>3. Adoption of agenda (please send suggestions *before* meeting)
>    Adopted with a change: #7 moved to just before #4.
>
>7. Choice of schema language position
>
>    The choice of XSD is as against other schema languages, such as RELAX NG,
>    DTDS, or Schematron.  It doesn't say anything about which features in
>    XSD to use, or which features available in XSD but not available in
>    other schema languages to avoid.  Keep in mind that the BL Schema
>    subcommittee recommended XSD as a recognition of reality.
>
>    Motion: "To use XSD as the source format for UBL business document
>    types."  Moved by Arofan and seconded by Dale.  Approved by unanimous
>    consent.
>
>    ACTION: Eve to write a section for the NDR document documenting the
>    choice of schema language, and a position paper for the archives.
>
>4. Action item review
>
>    ACTION: Arofan to create a new use case for instance constraint checking.
>    Continued until November 29.
>
>    ACTION: Arofan to write the position paper for extensions,
>    using a small but complete example of needing subtraction/selection and
>    addition.
>    DONE.  He will update as the need arises.
>
>    ACTION: Dave to create [use case] HTML template for people to use.
>    DONE. It's now a Word template.
>
>    ACTION: Mark to revise the NDR document to reflect editorial
>    directions by next meeting, if possible.
>    Continued until November 30.
>
>    ACTION: Arofan/Sue/Lisa to provide the xCBL naming guidelines (and
>    all the other xCBL guidelines!).
>    Continued until later today (November 28).
>
>    ACTION: Dale to generate a use case where the actor is an implementor
>    and needs to create a message with alternate (aliased) tag naming.
>    DONE.
>
>    ACTION: Mark to update naming position paper with our suggestions
>    (including email suggestions).
>    Continued until sometime before next meeting (December 5).
>
>    ACTION: Dale to revise 4.1, 4.2, and 4.3 to make them shorter and
>    provide a reference to the source whence the information came.
>    To be sent later today.
>
>    Note that new actions are listed in various places below.
>
>5. Current position paper champions, status, and priorities
>
>    Mark:
>    - Markup naming (A-priority)
>    - Design principles
>    - Relationship between UBL and UN/CEFACT constructs
>
>    ACTION: Mark to take a look at the original XML 1.0 design principles
>    to see if it's useful to add any of them to our document.
>
>    Eve:
>    - Choice of schema language (A-priority)
>
>    Doug:
>    - TPA
>
>    Arofan:
>    - Customization (A-priority)
>
>    Bill:
>    - Modularization/namespaces/versioning
>
>    Gunther:
>    - Elements vs. attributes
>
>    Dave:
>    - Use cases (not really a position) (A-priority)
>    - Local vs. global elements
>
>    Mike:
>    - Code (enumerated) lists
>
>6. Use case review
>
>    Invited expert: Maryann Richards.  She previously worked with the
>    Gartner Group, and is currently working with Dave.  She has a bit of
>    XML background, and a lot of use case background.  She will be helping
>    us coordinate our use cases.
>
>    Initial impression: The connection between use cases and the eventual
>    effect on design rules isn't quite clear yet.
>
>    Brainstorming on actors (non-normative; Eve's ramblings):
>    - User of UBL
>      . Developer who codes to UBL as is
>      . Business document instance creator
>    - User of design rules
>      . UBL library content designer
>      . Developer who extends UBL
>
>    We will continue this once we have the Marketing SC's input.
>
>    ACTION: Arofan to send a pointer to the draft ebtWG specification that
>    has a process diagram that will be helpful for figuring out use case
>    actors.
>
>    ACTION: Sue and Maryann to do some brainstorming offline.
>
>8. Tag structure position
>
>    We seem to have three options, not two:
>
>    1.  Highly structured with hierarchical information in the names
>
>    1a. Highly structured with XML ancestry providing the object class
>        and the type hierarchy providing the representation term
>
>        . Has most of the benefits of #1, but the subelements are more
>          reusable in different contexts.  Example: Tax structures and
>          bank structures need payment documents, but InvoiceTaxTotal,
>          FooTaxTotal, etc. (as opposed to just TaxTotal) artificially
>          expands the number of elements, makes long names, and requires
>          a lot more maintenance.
>
>    2.  Semi-structured, with intuitive naming taking precedence over
>        regularity
>
>    There are two circumstances we need to understand better:
>
>    - If a patient record is able to contain generic party information,
>      should a generic Party element be used, or a specific PatientParty?
>      How the former option be linked back to a core component, given
>      that the PatientParty option provides semantics not available in
>      the type hierarchy)?
>
>    - If a patient record needs to contain patient-specific party
>      information, and the generic party type is extended to serve this
>      purpose, should the element be called Patient or PatientParty?
>
>    It was noted that the issue of element reusability will affect our
>    decisions on the local vs. global element issue.
>
>    ACTION: Dale and Sue to work up examples and examine them in light of
>    the two "PatientParty" circumstances listed in the November 28 minutes.
>    Other interested parties are Mark, Arofan, Eduardo.  Due by December 5.
>
>9. Finish going through the NDR document outline and assign more champions
>
>    New position paper assignments:
>
>    Sue: 5.2.2 Standardization Conventions (not A-priority), with Dale
>    and Mavis as helpers.
>
>    Mark and Eve both took notes on this discussion.
>
>    ACTION: Mark to check with Mike on what the purpose of Section 5.4 is,
>    and follow up with editorial changes as necessary.
>
>    ACTION: Mark to insert into the NDR document links to the existing
>    position papers, with notes about their being extremely non-settled
>    and non-normative.
>
>10. Next steps
>
>     Our goals for the week of December 10 are:
>
>     - To take a snapshot of what we've got and show it off
>     - To make clear what parts are decided and what parts are still
>       under discussion
>     - To convey to vendors what features we'll need in their products
>
>     There will be at least a few UBL people around to hear Jon's talk.
>
>     ACTION: Eve to coordinate the delivery of the documents to Jon.
>
>     Agenda for next time:
>
>     - Legal issues (following on to Arofan's posting)
>     - Finish going through NDR document
>     - Continue and hopefully finish the tag structure discussion
>     - Hopefully start discussing the extensions paper
>     - Identify any easy holes to fill in the NDR document
>     - Come up with a list of messages we want Jon to give about schema
>       support (e.g. namespaces)
>
>11. Adjourn
>     Adjourned z:05.
