Hi Sean:

Here's another mail just commenting on the use of RDFa. Pretty sweet
to see this btw. I particularly liked seeing those dct:reference
assertions to other referenced documents.

I ran the output through the rdfa distiller [1] and got the Turtle
output (included below). I noticed that the dct:title is turned into
an XML Literal because of a <br> in the middle of the heading:

  dct:title """SKOS Simple Knowledge Organization System <br
xmlns="http://www.w3.org/1999/xhtml"/> Reference"""^^rdf:XMLLiteral ;

I guess in an ideal world it would just be a plain literal? Also I
noticed that you are of type con:person instead of con:Person like
Alistair. Just capitalizing yours should fix that right?

Also, I don't want to open a can of httpRange-14-worms but should your
hash URI be used instead?

      con:familyName "Bechhofer" ;
      con:firstName "Sean" .

I'm not sure what Alistair's should be. Oh, I just now see that Diego
wrote saying pretty much the same stuff in a clearer way ... so don't
feel like you have to respond to this.

<strong xmlns="http://www.w3.org/1999/xhtml">Abstract</strong>

<p xmlns="http://www.w3.org/1999/xhtml">This document defines the
Simple Knowledge Organization System (SKOS), a
common data model for sharing and linking knowledge organization systems via
the Web.</p>

<p xmlns="http://www.w3.org/1999/xhtml">Many knowledge organization
systems, such as thesauri, taxonomies,
classification schemes and subject heading systems, share a similar
structure, and are used in similar applications. SKOS captures much of this
similarity and makes it explicit, to enable data and technology sharing
across diverse applications.</p>

<p xmlns="http://www.w3.org/1999/xhtml">The SKOS data model provides a
standard, low-cost migration path for
porting existing knowledge organization systems to the Semantic Web. SKOS
also provides a light weight, intuitive language for developing and sharing
new knowledge organization systems. It may be used on its own, or in
combination with formal knowledge representation languages such as the Web
Ontology language (OWL).</p>

<p xmlns="http://www.w3.org/1999/xhtml">This document is the normative
specification of the Simple Knowledge Organization System. It is
intended for readers who are involved in the
design and implementation of information systems, and who already have a good
understanding of Semantic Web technology, especially RDF and OWL.</p>

<p xmlns="http://www.w3.org/1999/xhtml">For an informative guide to
using SKOS, see the <a href="http://www.w3.org/TR/skos-primer">SKOS
