Subject: Re: [regrep] Summary: Issue with UUID's for Core Components and BIE's
David: I do not think we are disagreeing. This approach does not "lock" them to ebXML Registry, just allows such. I have done nothing nor am I advocating doing anything that creates such a dependency. I am working to make it possible in alignment with the charter and mandate of the OASIS CC-Review Sub TC and the spirit and intent of the ebXML TA and requirements. I would envision that modellers will use the BIE's and CC's outside of the registry in most cases, but require access to certain bits of information within the registry. In fact, collaboration on business models is a cornerstone of UMM, CCTS and BCM. I would strive that we make every attempt to avoid constraining the BIE's and CC's and the methodology of UMM to be dependent on a registry, yet make it possible to do such. It should also be possible to accommodate other registry UUID formats perhaps? I have not confused UID and UUID. They are not mutually exclusive as you correctly point out however, a UID that is not guaranteed to be universally unique is not acceptable as a UUID. Therefore, the correct statement is that a UUID may be used as a UID, but a UID that is not guaranteed to be universally unique is not acceptable as a UUID. A 128 bit formatted DCE UUID is acceptable as both. Since ebXML has already specified UUID in the 128 bit format, there is no point in discussing this further. What I would support, reading between the lines of your email, is the use case for UID's other that the UUID to be present in a serialization. This use case does have merit IMO and there may be an advantage for data transformation people to use more than one UID to help in mapping to internal back end systems data models. The model can be flexible enough to allow support for other than ebXML registry alone. I do not think you and I are disagreeing on anything are we?
