Subject: RE: [ubl-lcsc] Formulating a response to the UDEF discussions
Perhaps we can give a technical comparison on CC UIDs with UDEF IDs and let Ron know our requirements so Ron can help us in the strategic and technical direction.

Strategic and technical feedback to the UDEF team is warranted and desired, and Ron is looking forward to addressing the questions.

With respect to the technical issues, i think we need to be clear what our options are. For example, does the UDEF ID give us any advantage over our own Unique IDs (or CC UIDs)? Also, I would still like to give some feedback to Ron in recognition of the effort he and sally put into their presentation. Maybe i should rephrase my response to separate the first two questions from the third. What do you think? Bill French wrote: Tim, I've been involved with the UDEF effort. A couple of points: - The UDEF effort is being driven through the Aerospace Industry Association (AIA). EIA is the Electronics Industry Alliance... different group. It's an important distinction however, since UDEF adoption by the AIA will likely lead to adoption by the US Government, especially the military and defense sectors. That said, the high tech sector, EIDX, is putting UDEF into it's cross-reference models. - The UDEF team has been cognizant of the Cefact CC work. However, further alignment will be necessary (which they realize), and I know there are folks who are interested in making that happen who are actively involved with UDEF (me included). - They do have a proposed governance model. What I would propose is that we ask Ron Schuldt, who is the co-chair of the UDEF team, to present this model to the liaison team. If that's acceptable, I can make those arrangements. regards, Bill -----Original Message----- From: Tim McGrath [ mailto:tmcgrath@portcomm.com.au] Sent: Tuesday, December 03, 2002 10:32 PM To: ubl-lcsc@lists.oasis-open.org Subject: [ubl-lcsc] Formulating a response to the UDEF discussions At yesterday's meeting I was tasked with drafting a response to Ron Shuldt, the chair of the EIA Industry group follow the presentation Sally gave on the application of UDEF to the work of UBL. Here is my first draft. Please add your thoughts to this and send them directly to me. I shall edit these into a final version for submission before Tuesday 10th Dec. "The UBL team acknowledge the value of the architectural model described by UDEF. The idea of using a hierarchical assembly of objects and their propoerties which cna be identified by an independant coding system. This formalizes a vocabulary and promotes interoperability by allowing differing names/tags to refer to the same semantic component. In summary the question that rose to the surface was that this architecture is somewhat similar to that proposed by ebXML Core Components with their naming convention and identification scheme equivalent to the Core Component Technical Specification and the CC UID. UDEF could be described as a type of Core Component Library. As UBL is committed to compliance with the ebXML Core Component Technical Specification, this could create some issues for us. For example, if the UDEF Object Tree or Property Tree do not align with the Core Component Library then we would have potantially duplicate UDEF IDs or no equivalent UDEF ID at all. We therefore have a few further questions we would like to put to the UDEF team: 1. How do they see the alignment of the UDEF structures with that of the CEFACT Core Component work? 2. How do they see the ongoing governance of the UDEF structures with that of the CEFACT Core Component work? 3. What added value does the UDEF ID give other than that already provided by the CC UID (ie they both appear to offer interoperability mapping)? We appreciate your advice on thse matters. As you will appreciate, our concern is that we do not embark on parallel developments and thereby create even greater fragmentation in this community.
