[Fwd: Re: InfoWorld: OASIS seeks URI scheme that accommodates XML, Web serv ices]

At the request of my fellow countryman Mark Baker,  here are some brief 
details of what ebXML needed.

IN ebXML, a lot of work has been done in the area of semantics.  IN 
particular, ebXML has devised a list of business element meta-data 
called "core components".  These are things like "Telephone Number" or 
"Invoice Sub Total" etc.  Because many disparate vocabularies exist 
today and all use their own element names for these items, the business 
requirements of ebXML users was to be able to positively identify that 
element "x" in one vocabulary was equivalent to element "y" in another 
vocabulary. (within certain contexts - heirarchal and other).  The way 
we decided to do this was to use a Globaly Unique Identifier.  Many 
different ideas were submitted for what these GUID's should be but most 
favored some sort of URI based scheme.

A similar use case is needed in ebXML for identifying Business Process 
instances, Business INformation Entities and other artifacts.

The architecture team determined that to accomodate all the use cases 
and requirements, the GUID's would have to:

1.  be capable of uniquely identifying an artifact
2.  be capable of relaying information where the master copy of the 
artifact is located
3.  identify the protocol used to retreive the artifact

David Orchard and I had a whiteboard session here in Vancouver and 
examined the requirements in greater detail (in addition to planning a 
great snowboarding trip to Whistler, BC).

Some excellent work has been done in this area including a few great 
RFC's by Michael Mealling, some really good ideas by Chris Ferris and 
now William Kammerer has also written a proposal on this subject (sorry 
for not including the URI's to any of these).

Best wishes

Duane
