Carl and all on the reg/rep group:

I'm not sure I've got the ability to post to the OASIS group that 
originated this list, Duane, can you post this to the right groups for me, 
and copy me so that I can capture these email address for the groups (then 
get more deeply involved)? THANKS

One of the classic uses that we have planned for in the UDEF groups is the 
"linkage" between schemas, ontologies, taxonomies and data dictionaries, 
what have you. For example, the data element concept 
"purchase.order.document_date" where "purchase.order.document" is the 
object (document) with qualifiers ( of type 'purchase order') and where 
"date" is the property of the document, is represented in the UDEF 
semi-intelligent ID format as d.t.2_8 or "purchase.order.document_date".

So taking this and placing it in the schemas or RDFs etc, as an attribute 
of the data element concept that is used in that format to specify the 
purchase order document date, will provide a linkage between all the docs 
that have that data element concept. And as you are probably well aware, 
every PO has the data element concept of PO Date, but very few, if any of 
the formats call this data element by the same name. So the attribute can 
be resolved to provide the exact semantic meaning of the data element. 
There are two example XML instance docs on the home page of the UDEF web 
site (http://www.udef.org) one is OAGIS and the other is xCBL 
(commerceone). The UDEF IDs are really improperly placed in the actual 
instance docs, only for demonstration purposes. We think that this really 
belongs in the reference doc (ie: schema, RDF, etc).

In my mind, this is very useful information to have in some form or fashion 
within the reg/rep, due to the fact that the reg/rep holds integration 
artifact info, and this most certainly qualifies as that. I still don't 
have any opinion on how or where it should be stored in the reg/rep... Can 
we perhaps start on some conversations?

thanks
john

PS - there is an upcoming NIST / OAGi / UDEF Proof of Concept. See 
http://lists.topica.com/lists/udef.builders/read/message.html?mid=808601884&sort=d&start=142 
I would also like to include CAM assembly paradigms and mechanisms in this 
if we can....

[UDEF] Class of Applications fit within the ebXML Semantic Registry ?

This is interesting. I want to now more..

Zach:

Please expand on the notion of 'UDEF semantic identifiers'.

Evan:

Please elaborate on 'lattices of these relationships '.

Everyone :

Please consider if the Semantic Web could leverage "concepts ... denoted
by the paths from these nodes to the root rather than the node itself"


thanks much
carl
