   UDEF was Re: [xml-dev] Fun With Schemas]

[ Lists Home | Date Index | Thread Index ]

Thanks for the reply David - it's going really, really well. The UDEF is 
currently entirely DTDs as individual object or property trees and all the 
qualifiers as children. Using XSLT and other XML tools (XPath, etc) it can be 
resolved into any number of formats (as planned) and also into a rendered GUI to 
provide web based browsing and other tools, as described here:

Re; progress and the near future for UDEF -
The IP owners (aia-aerospace.org and afei.org) have been working diligently to
find a permanent, royalty-free home where they can establish the UDEF reg/rep,
which is basically a home for the UDEF trees that are now expressed in DTD,
along with a  suite of applications designed for a variety of user types to use
in creating UDEF IDs for addition to thier formats, or suggesting additions to
the UDEF trees so that the data element concepts that are missing can be
represented. User types range from enterprise IT shops, software vendors,
individuals, standards and industry bodies. All will have free access and
royalty free use of the tools to browse the trees, suggest additions (which will
be reviewed by a domain expert group of peers before addition), and resulting ID's.

There will also be a registry for libraries, ontologies, taxonomies, etc...
which have been UDEF enabled (UDEF'ized...) where the standards bodies, IT
shops, etc, can place their schemas, DTD's, RDF's, OWL's, etc. for use by either
public or authorized groups. This meant to foster the entire effort and provide
integration engineers with access to the formats that they need in order to
create more agile and (hopefully, eventually) nearly automate integration tasks.
That's my personal goal... probably un-reachable, but then again...

The Open Group (http://www.opengroup.org) is in the process of reviewing the 
requirements for potentially becoming that host.

Once the host is selected, there will be a build effort to create the reg/rep, 
and then enlist the subject matter / domain experts to use the admin interfaces 
in an effort to round out the trees so that they provide all data element 
concepts required in each industry.

This is a huge effort overall, but gaining massive amounts of steam, with
cross-industry, huge-enterprise and standards body support. We envision the day 
when simple matching tools and the UDEF enabled XML, RDF or other formats are 
used to provide a very much easier integration mapping paradigm.

Joining the Open Group udef group is free at 

Persons that are interested in helping build out the trees should contact 
ron.l.schuldt@lmco.com and/or chris.harding@opengroup.org

More detail on the actual trees themselves and the architectural design / use 
cases up to this point can be seen at http://udef.org/specdoc.html
