Notation3

<h2 id="examples">Examples</h2>
<p>The following is an RDF model in standard XML notation:
</p>
<rdf:RDF
    xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
    xmlns:dc="http://purl.org/dc/elements/1.1/">
  <rdf:Description rdf:about="https://en.wikipedia.org/wiki/Tony_Benn">
    <dc:title>Tony Benn</dc:title>
    <dc:publisher>Wikipedia</dc:publisher>
  </rdf:Description>
</rdf:RDF>

<p>may be written in Notation3 like this:
</p>
@prefix dc: <http://purl.org/dc/elements/1.1/>.

<https://en.wikipedia.org/wiki/Tony_Benn>
  dc:title "Tony Benn";
  dc:publisher "Wikipedia".

<p>This N3 code above would also be in valid <a href="/facts/Turtle_(syntax)/PD2stm7f">Turtle</a> syntax.
