Subject: RE: Example RN PIP 3A4 in BPSS
Jean-Jacques, Would this be an accurate paraphrase of the idea you expressed below: keep collaboration logic in the collaboration model - don't make it dependent on the document contents - so you can use the same collaboration logic with different document formats? (I'm not trying to rewrite your message, just to confirm that I understand the idea, which I think I support...)

I would like to emphasize one point: we should avoid using XPath expression on the message document because this makes collaborations much less reusable across standards. I understand that this is not feasible in the case of RN but moving forward, a good design principle would be to use distinct document formats to express different intend. The binding at the format level would happen in the DocumentSpecification. This might look like a little step one way or the other, however, converging at the "business collaboration" level is even more important than converging at the format level. Formats can most often be mapped to each other, it can quickly become un-manageable to map and adapt business processes to a slew of nearly identical collaborations. Once a collaboration is in place an agreed upon by an industry or an eco-system, it is relatively simple to manage N different document formats flowing through the same infrastructure as they are nicely decoupled from each other.

I think it is correct, but if someone finds a mistake or I left something out, please let me know. Some interesting points: * Use of Packages to represent Cluster, Segment and PIP * Use of guardExpression and XPath to determine the response type, since RosettaNet uses the same message for both positive and negative responses. * Use of XPath to reference other elements. * Only 74 lines of XML for the entire PIP! <<BPSS_RN_PIP3A4_example.zip>> Best regards, P.S. I will not be able to attend the Vienna meeting, hope it is a great one! ________________________________________________________________ Kurt Kanaskie IT Architecture Strategy Group Lucent Technologies kkanaskie@lucent.com (610) 778-1069 ------------------------------------------------------------------ To unsubscribe from this elist send a message with the single word "unsubscribe" in the body to: ebxml-bp-request@lists.ebxml.org
