Subject: Re: [ubl-comment] UBL op70 Schemas released for public review
Hello Mounir, We are very grateful indeed for the comments of CEN/ISSS regarding UBL version 0p70. As noted in the review response you enclose from Freddy De Vos, I and several other UBL members will be in attendance at the UN/CEFACT Forum meeting in San Diego. I can assure the authors of those comments that meeting with the TBG groups to discuss UBL is very high on our list of priorities. The disposition of the CEN/ISSS comments will be taken up after our return from San Diego. The procedure we have established is to devote ourselves during the review period ending 14 April to the collection and categorization of comments (which due to the number of comments received is proving as big a job as we anticipated), to order the comments for disposition during the week following, and then to have all the comments out to the members of the UBL TC during the week of 21 April in preparation for the TC meeting at APACS in London 28 April through 2 May. Since OASIS is a publicly visible process, members of CEN/ISSS can of course monitor this work through the ubl and ubl-lcsc mail archives, but it's unlikely that the disposition of specific comments will occur before then. I will, however, attempt to respond to the more general questions posed in the CEN/ISSS comments, with the proviso that I am speaking outside of our TC process as an individual and in the hope that other members of the TC will supplement and clarify these remarks if necessary. The CEN/ISSS reviewers ask: | - We would like to have a proper understanding of the reasoning | behind the architecture of the Class Diagram and the | messages. Is it possible to have the business/information needs | of the users as well as conclusions reached by the working | group that developed the diagrams? Are there reports or | summaries of meetings that we could follow through the design | process? To take the last part of this first, all of the UBL subcommittee meetings are recorded in the archives: http://lists.oasis-open.org/archives/ubl-lcsc/ http://lists.oasis-open.org/archives/ubl-ndrsc/ If one wishes to understand the reasoning behind the current release, however, then I think one will do better to consult the position papers prepared by the members of the Library Content Subcommittee and the Naming and Design Rules Subcommittee. Current versions of those documents are linked to from the subcommittee portals: http://oasis-open.org/committees/ubl/lcsc/#documents http://oasis-open.org/committees/ubl/ndrsc/#documents | - On which base have these message been constructed? Are they | based on business process diagrams? On concrete examples from | an industry sector? The emphasis in UBL is on industry experience rather than formal process descriptions. However, you will find the trading scenario assumed by the current version quite well diagrammed in the section of the release package titled "Initial UBL Business Scenario." See Section 5 under http://oasis-open.org/committees/ubl/lcsc/0p70/ | - In some instances it is said that the messages have only to be | developed for the purpose of creating the library of business | information entities. In other instances, including your | e-mail, the messages are presented as core messages for | everybody i.e. to be actually used, starting point for more | dedicated messages, This is creating confusion and should be | clarified. UBL is attempting to define both a library of reusable XML schema components (BIEs) and a set of basic generic business document schemas assembled from those components. If we could produce only one of these deliverables, then of course it would be the BIE library. But we believe it to be of importance to produce not just the library but also some normative documents based upon it. I cannot speak for the rest of the TC, but my personal interest in the basic documents is to promote the entry of small and medium-size businesses into electronic commerce. It is my belief that standardized XML versions of such universally employed business documents as purchase orders and invoices will provide the easiest and quickest migration path into electronic commerce for businesses all over the world. For this reason, I personally find the basic trading scenarios and document examples in Section D.5 and the formatting specifications and stylesheets in Section D.4 the most interesting parts of the review package, even though they are secondary deliverables from a technical standpoint. It is my hope that the release of version 1.0 of the basic UBL document schemas and supporting materials later this year will have an effect on electronic commerce not unlike the effect that the even simpler and more limited HTML tag set had on electronic publishing a decade ago. Satisfying the use cases encountered in EDI will, of course, require the standardization of a much larger number of more specialized document schemas. UBL is intended only as the starting point for this work, which is expected to take place in industry groups having the necessary domain expertise.
