Subject: UUID and GUID
Hello UBL TC, At the Manhattan UBL TC meeting, I took the AI to check on UUID vs. GUID and figure out which of these was proprietary. The answer to that question is: GUID is a proprietary Microsoft implementation of UUID. We can't be referencing proprietary specifications here, so we have to use UUID. (The OASIS ebXML Registry Standard has always used UUID, by the way.) Consequently, we will have to change all occurrences of GUID in the schemas to UUID. I'll enter this in the issues list once we settle on a UUID reference. The reference question is not as simple as one would hope. For background, see the Wikipedia entry on UUID. Here's my take after reading that article and doing a little bit of checking around: - The original 1997 UUID spec from The Open Group is not what we want, despite the fact that this is the spec referenced in ebRR 3.0 as [UUID] DCE 128 bit Universal Unique Identifier http://www.opengroup.org/onlinepubs/009629399/apdxa.htm#tagcjh_20 - Possible UUID specs include: - ISO/IEC 11578:1996, which is not freely available online - IETF RFC 4122, which is available at http://www.ietf.org/rfc/rfc4122.txt http://www.rfc-archive.org/getrfc.php?rfc=4122 ftp://ftp.rfc-editor.org/in-notes/rfc4122.txt - ITU-T Rec. X.667 (2004) | ISO/IEC 9834-8:2005, which is based on RFC 4122 and can be found in "prepublished" form at http://asn1.elibel.tm.fr/en/tools/oid/standards.htm http://www.itu.int/ITU-T/studygroups/com17/X.667.pdf Ordinarily I would go with the RFC simply because it's freely available. However, the ITU-T/ISO/IEC spec is also freely available as an exception to the usual rule, and I'm informed that an agreement between ITU and ISO will keep it that way. So my recommendation is to reference that one unless someone sees a reason not to. Please post any thoughts you might have on this, and let's aim to resolve the issue in next week's Atlantic TC call.
