title: When and why is ns0pred used?
body: <p>Greetings,</p>
  
  <p>As I am beginning with RDF building, I came along ns0pred here and there. 
  I am assuming ns means no subject and pred means predicate. Not sure on the zero other then a false boolean value.</p>
  
  <pre><code>&lt;rdf:Description rdf:about="http://localhost:8890/dataspace/test3/wiki/testWiki/MyTest"&gt;
  &lt;ns0pred:label xmlns:ns0pred="http://www.w3.org/2000/01/rdf-schema#"&gt;MyTest&lt;/ns0pred:label&gt;
  &lt;/rdf:Description&gt;
  </code></pre>
  
  <p>There is a little example. </p>
  
  <p>Would I be correct if I said, use ns0pred prefix when there is no available prefix like the basic ones (ex:name for example)?</p>
  
  <p>Are there any downsides to ns0pred I should know about before going any further with my RDF data?</p>
  
  <p>Kind regards,
  Joris</p>
