We will handle Ontology as UBL Extension.

For the record, the following email is the
supporting material behind the decision noted in
the minutes of the above Pre-award meeting
regarding accommodating the W3C Ontology.

Subject: Organization identification as an extension
Cc: Oriol Bausà <oriol@invinet.org>

Hi, Ole.  I promised to write up a summary of
Kees's important suggestion regarding using the extension point.

If we consider section 5.10 on page 18 of this
PDF you cited, the legal entities must follow various models found at:


The partial example given in section 1.1 of that
ontology document regarding the UK Cabinet
Office is expressed using RDF 1.1 Turtle syntax:

    rdf:type org:Organization , central-government:Department;
    skos:prefLabel "Cabinet Office" ;

The complete version of that example can be
found on the web in XML syntax at this URI:


No doubt some people will find such a level of
detail useful, and it appears that the European
Commission has decided that they need this to be
in the document information we want to put into
a UBL document.  No doubt there will be many for
whom such detail is not needed.

UBL was never meant to solve every detail for
every user.  Rather, we wanted to accommodate
every user by standardizing the bits likely
useful to all users and providing a place for
the bits some users would find necessary for
their specific and unique needs.  That place is
the extension point, whose scaffolding is
standardized for every UBL document, but whose
contents is wholly up to users to agree to use.

Thus, we can meet the requirement for 5.10 by
suggesting the use of UBL standardized bits for
describing a Party to a satisfactory level of
detail needed to distinguish parties for the UBL
semantics, and the use of the extension point to
associate the W3C level of detail of an
organizational description with the UBL Party.

Consider the attached example (which is schema
valid) that is not to be considered definitive,
rather, it is simply illustrative of an approach
that might be built upon to create a complete solution.

<?xml version="1.0" encoding="UTF-8"?>
       <eco:Organization xmlns:eco="urn:X-EC-Organization">
<result format="linked-data-api" version="0.2"

      <item href="http://reference.data.gov.uk/id/department/co/post/38";>

  <definition href="http://organogram.data.gov.uk/api#postInDepartment"/>
      <cbc:ID schemeName="GLN">123456789</cbc:ID>

Using this approach, the organization
description can be as simple or as detailed as
the user wishes, without impacting on the UBL
essence of a Party.  In my example I've
associated the extension with the party by
identifying the href attribute of the linked
data API result instance.  It would be
unique.  In fact, it could also be directly
dereferenced, but I wouldn't recommend it for
legacy purposes, as you would want a copy in the
instance to be what the details were when the
instance was created.  If an auditor was asked
to always dereference the URI then he wouldn't
know if the contents at the URI were different when the document was issued.

Not only are we saving the effort of trying to
keep up in UBL with any changes the W3C might
make to its ontology over time, we are keeping
it simple for the vast number of other UBL users
who have no interest in the W3C ontology.

Thanks, again, to Kees for his insights.
