Hello,

The "foaf" prefix is not declared in the example from section 11.2.1.4.

PREFIX a:      <http://www.w3.org/2000/10/annotation-ns#>
PREFIX dc:     <http://purl.org/dc/elements/1.1/>
PREFIX xsd:    <http://www.w3.org/2001/XMLSchema#>

SELECT ?annot ?given ?family
 WHERE ( ?annot  a:annotates  <http://www.w3.org/TR/rdf-sparql-query/> )
       ( ?annot  dc:creator   ?c )
         OPTIONAL { ( ?c  foaf:given   ?given )
                    ( ?c  foaf:family  ?family ) }
   AND isBlank(?c)

Thanks,

-bryan
