Clearly a document requires identification of the parties involved, but our schemas have no mandatory ones. that is because whilst it is required to have parties we cannot mandate which type of parties must be defined. Sometimes the Consignee, sometimes the Freight Forwarder - depends on the context of use. In this situation stating here are my shipment details in isolation, may be technically valid but not much use. >> i suspect ken was seeing value in a "meets all mandatory >> requirements" generic model for minimum compliance checking. but i am >> think this is more a technical objective than a business one. > > > Kind of ... but is there a business benefit enabled by the technical > enabling of a transaction of core information upon which the receiver > adds what is needed. > >> in fact there is a danger here that this type of model may become a >> target for compliance in application interfaces. i am not sure we >> want that. > > > I think it is worth discussing. > OK, I see now your vision of Open-UBL. This is another part of the customization puzzle we should consider in the approach we are defining. You are proposing a minimal subset (or what i would call a "core pattern") for each document type. An approach Bob and I refer to as "Core plus Contextualization" in our [highly acclaimed] book. However i suspect what actually constitutes this "core" or miminal subset, cannot be automatically derived from our models or schemas. It seems to me more like another SBS-type project. > Thanks, Tim! > > . . . . . .
