1. Paraphrase in natural language what the following RDF/XML code fragment means:

   <?xml version = "1.0 "?>
       <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 = "http://www.ics.mq.edu.au/~rolfs/index.html">
            <dc:creator
                rdf:resource = "http://www.example.org/staffid/98972"/>
         </rdf:Description>
       </rdf:RDF>
   

2. Express the above RDF/XML example graphically in RDF triples.
3. How would you formalise the following statement graphically in RDF triples:

          complementOf( restriction hasPart someValuesFrom Meat)
          complementOf( restriction hasPart someValuesFrom Fish))
