Dear Dublin Core project members,
Please take a moment to review the Universal Data Element group
http://udef.org, as it appears to be attempting a solution that has some
overlap with CORES and Dublin Core, but also might contribute to a solution
for achieving cross-domain, cross-platform and multi-format semantic
identification. I believe that it also has application as a language
translation tool as it isn't language dependent.
A brief explanation:
Universal Data Element Framework, is an upcoming open-standards effort to
tackle the problem of semantic equivalency between formats, domains,
ontologies, taxonomies, etc. It is coming out of AFEI and the Aerospace
Industry Association and has been the subject of some activity within
eBusiness standards domains. This effort is planning a globally available
reg/rep with semantic tools to define and resolve semi-intelligent IDs,
which can then be used to identify semantic equivalency. A link to the XML
Cover pages writeup on it is: http://xml.coverpages.org/udef.html Although
this particular reference is focused on XML, RDF / OWL is one of the
primary outputs / reference formats envisioned as the representation of the
UDEF trees (UDEF trees can be viewed in a presentation format at
http://udef.org/specdoc.html along with use cases for the reg/rep functions).
But here's the proposal: All formats adopt an attribute for each data
element. The UDEF is a set of trees that are hierarchical in nature, with
primary Object words (Object, Entity, Place, Process, etc.) with qualifiers
(order.document or contract.document for example) and Property words
(identifier, date, measure, amount, etc. ) again, with qualifiers. Each is
assigned a letter or number, and then these are used to string together
semi-intelligent semantic identifiers. IE: purchase.order.document_date
comes out to be d.t.2_8. These are then added to the ebusiness format's
reference document, ie: schema, rdf/owl, or what have you.
There will be movement this year towards making it an open standard, and
building a UDEF registry / repository where users can go and create IDs for
data element names, and then use these IDs within their formats.
We would like to collaborate with Dublin Core and the CORES groups to reach
a common solution that can bridge the eBusiness and Semantic Web
disciplines. Your input is greatly appreciated, please forgive the
Thanks for the time, best regards.
