Subject: FW: Information on the UDEF - semantic equivalency mechanism

XDI TC Members and Observers (and also XRI TC Members and Observers):

I am forwarding this reply from John Hardin of UDEF.ORG who doesn't have
permission to send directly to the lists.

Gabe, I note for the XRI TC that we discussed UDEF six+ months ago, and John
and his colleagues should definitely be able to help us understand the
intersection better now.

Subject: RE: Information on the UDEF - semantic equivalency mechanism

Thanks very much, I will replace the paper I had printed <shame on me for
killing trees>. 

Also - I am copying you on an email that just went between myself, David RR
Webber and Joseph Chiusano, regarding UDEF and CAM. 

I think between these groups, and including the Reg/Rep, and some work by
the ontologies/taxonomies/RDF/eBusiness Schema formats etc, we can come up
with a very usable semantic equivalency mechanism for web services, B2B and
eventually, the semantic web... 

Thanks for the interaction. Incidentally, I will be registering
http://www.sanghainteractive.com (my company) as a OASIS technical member,
and I believe should probably start a UDEF Technical Committee. 

What are comments from any and all on that?  

John Hardin

>Hello to the OASIS DataWeb team,

>The Universal Data Element Framework (http://www.udef.org) is an upcoming 
>open standards effort that is gaining steam in the international IT 
>community. We are focused on developing and delivering a royalty-free, 
>global resource for  "semantic equivalency". The method is to provide a

>representation words for Object (18 total) and Property (16 
>total),  eBusiness document formats, ontologies, taxonomies, for use as 
>data in web services and the semantic web.
>Some details:

>Use cases for mechanism on registry / repository -

>There is a NIST / Open Applications Group Proof of Concept in progress: 
>The announcement of the permanent host for UDEF Registry is upcoming...
