MINUTES OF PACIFIC UBL TC MEETING 00H30 - 02H30 UTC TUESDAY 19 APRIL 2005 ATTENDANCE Jon Bosak (chair) Micah Dubinko Stephen Green Betty Harvey Tim McGrath Sylvia Webb STANDING ITEMS Additions to the calendar (http://ibiblio.org/bosak/ubl/calendar.htm) None. Liaison reports None. Subcommittee report: HISC MicahD: The SC worked out a system last week whereby all the configuration for the script that generates the kernel of the input specs is in a separate file that can be edited by someone who doesn't know python; this should be good for customizers. Subcommittee report: SBSC StephenG: Received edits from JonB. It will take a while to incorporate the input. Team report: European input to 1.1 StephenG: Attended the meeting in Paris Friday. Learned that Sweden has a major implementation of UBL Invoice in the works, similar in scope to the Danish effort but apparently independent of that. Sweden has been working mainly with small businesses and is interested in joining the SBSC. The Swedish approach to small businesses uses a combination of an implementation guide and a subset. They are also deploying an online validator that uses ebMS over HTTP to allow a message to be sent, received, validated, and then responded to in a way that depends on the result of the validation; this allows users to try out an ebMS implementation of the Invoice online. A lot of significant parties are involved in this effort. They will send Stephen a paper on this that we can refer to. The Paris meeting itself was occupied mainly with OGC input, much of which failed to gain agreement from the other participants. We will probably need to make decisions on the unresolved points based on the final report. The last F2F meeting will be held 4/27, with a wrapup phone conference 4/29 and input due 5/2 or 5/3. Team report: Versioning StephenG: The team has made considerable progress. A brief meeting was held today, StephenG and ArofanG attending. It appears based on a conversation with Jostein in Paris that the two-schema approach will work and might even be accomplished using an XSLT transform to turn the UBL schema into the ATG schema, raising the possibility that we need only publish one schema together with the transform. DavidK agrees with the emerging solution. Implementing it would require one major change: making everything in UBL global. This would not affect the semantics or even the XPaths, but it would require us to defer implementation of "polymorphism" for 2.0 or make 1.1 into 2.0. ArofanG thinks we should do this sooner rather than later, as the break with backward compatibility is purely technical and doesn't affect the semantics. ACTION: ArofanG to summarize the considerations discussed by the team and its conclusion regarding polymorphic schemas in time for the Atlantic TC call. ACTION: StephenG to distribute prototypes in time for the Atlantic TC call. ACTION: ArofanG to distribute a set of example fragments in time for the Atlantic TC call. CONTENT WORK SESSION The content team under the direction of TimM reviewed feedback to the Tax XML TC: http://lists.oasis-open.org/archives/ubl/200504/msg00062.html It was noted that the additional document types requested by the Tax XML TC are already targeted for inclusion in 1.1. SylviaW: We need to distinguish between wishes and regulations so that we can be sure to implement everything required by regulations. ACTION: SylviaW to convey our comments to the Tax XML TC at its meeting this Wednesday and check to see whether final input will be delivered as previously scheduled. NEXT WEEK TimM will chair in the absence of JonB, who will be attending the OASIS meeting in New Orleans. The agenda for the content work session will depend on new issues received during the week.
