How/whether to incorporate CCTS feedback into the NDR document We developed a fairly fleshed-out metamodel in our CCTS feedback. Should we capture this in the NDR document? The difficulty is whether this appears to compromise our commitment to adhering to CCTS. On the other hand, we want to show the connection more than we currently do. We agreed to include the information; the connection to the XSD metamodel is especially useful. New ACTION: Mavis (working with Bill) to incorporate the metamodel into the Relationship to CC section. 4b. CIDX update Eve described her recent visit to a meeting of the Chemical Industry Data Exchange. Along NDR lines, she was able to confirm that our code list decisions are pretty much on target. 4c. (ad hoc agenda item) X12 joint meeting We think that getting X12C/TG3 and the UBL NDR SC together is a good idea. We think 1.5 hours, with .5 hour each for information transfer and .5 for joint discussion, would be good. New ACTION: Eve to work with Mike Rawlins on figuring out a schedule. 5. Modnamver We reviewed the new modnamver-04 draft and worked through Section 10. We agreed with the Import Rule and the Include Rule, noting that this allows only flat inclusion structures inside RootSchemas (only RootSchemas can include InternalModules) and that we're okay with this for now. We haven't agreed yet on the Circular Dependency Rule; Bill will look into it further. We agreed that "minimaless" and "othogonality" are good goals, but they need to be explained further. We reviewed the two revised diagrams and made a few small suggestions. We considered expanding our recommendation to allow for intermediate RootSchemas that contain "limited common" structures that are common only to a small set of business message types. For example, tax information might only apply to certain shipping/logistics document types. xCBL has found a need for this. Bill moved that we add a recommendation allowing two or more functional areas to share definitions common between them but not used elsewhere by creating and importing an additional RootSchema, where the criterion for creation of this additional level of namespace is that it not be used in a majority of the functional areas. Motion PASSES unanimously. (This means that we've essentially accepted Option 4.) New ACTION: Arofan to write up his concern about importing indirectly so that Bill can research the issue. Section 6, on schemaLocation, should really be about the actual location of our actual schema modules; we don't have control over what instances put into real schemaLocations (e.g., they could even be URNs and use catalogs to resolve them). Then again, we might even want to encourage the use of URNs and catalogs, and get OASIS to run a URN resolver. Next time, we'll plan to decide whether to use URNs and/or URLs for namespace names and schema locations, and also decide how this affects our inclusion and importation strategies (because it's not just instances that need to mention namespace names and potentially schema locations -- it's our own modules). 6. Local vs. global elements Deferred. 7. Facets Deferred. 8. Schedule updates May 29: approve NDR document for distribution - Decisions that have to be incorporated: code lists, CCTS metamodel, modnamver, possibility of reconsidering local vs. global May 30: NDR dist #2: NDR document and position papers - Fresh versions of position papers to publish: - (Not tag structure) - (Not local vs. global) - (Not CCTS feedback) - Modnamver (Bill needs to update!) - Code lists (Eve needs to update!) - Elements vs. attributes (Arofan to press Gunther to update it) June 3-7: F2F meeting NDR SC members planning to attend the F2F so far: Mavis, Arofan, Jessica, Sue (mostly in LC mtgs), Lisa, Gunther, Eve, Mark, Eduardo. Bill definitely can't attend. 9. Adjourn Adjourned y:53. -- Eve Maler +1 781 442 3190 Sun Microsystems XML Technology Center eve.maler @ sun.com
