Subject: re: [regrep] FW: Reg Rep Requirement for UID scheme - Question?

[as a lurker and a member of the ebtwg architecture team]

There is (at least) one other effort that I think should be considered.
The Universal Data Element Framework (UDEF)

is an initiative for data harmonization led by the aerospace industries and
seems to be a good candidate for global unique identification.

                    04/04/2002           Question?

According to our working draft of the Architecture, (still not approved
by the team),  the UID has to provide three functional things:

1.  A unique identifier
2.  A way to locate the Registry (probably some URI scheme)
3.  A way to identify the protocol used to talk to the registry.

These three things must be present for UID's that are to be considered
candidates for use in all phases of ebXML.  The leading candidate being
discussed right now is a URN variance that includes the registry url.
IT still doesn't meet #3 above becuase we may end up with competing
registry standards in the future.

The current scheme of

UID="urn:uri:com-xmlglobal-registry:foo808112"  can make use of the
logical UID David talks about, and includes the location identifier (as
the URL), but still does not specify it is an ebXML registry.  The way
ot fix that may be to namepsace qualify the UID as such:


or other use of qnames.  We plan to recommend that a special team be
set up to deal with this issue as a subset of the UN/CEFACT eBusiness
Architecture team.  It sounds like both of you are prime candidates for
involvement <wink-wink nudge>
