Solution

  • The general pattern is something like this:

    SELECT ?individual
WHERE { ?individual a <uri-of-specific-class> ;
                    <uri-of-property> ?propertyValue .
        FILTER(STR(?propertyValue) = "expected value")
}

    You will need to adapt this with the details of your specific ontology (the URIs of your class names and properties), but it shows the general approach. I would also suggest that you try out a SPARQL tutorial, there's several good ones online for you to find.
