Sparql dbpedia query

I want to make a query ( SPARQL) to select from dbpedia DB:

Example : i want to find the definition of name Victor 

PREFIX foaf: <http://xmlns.com/foaf/0.1/>
CONSTRUCT { <http://example.org/person#Alice> foaf:description ?x }
FROM <http://example.org/foaf/people>
WHERE { ?x foaf:name ?name }
ORDER BY desc(?name)
LIMIT 10

I Think there's no foaf property called description , so i need the query which return this property

The DBpedia dataset has meanings of names. Here is one way of querying them with SPARQL:

PREFIX  dbpedia-owl:  <http://dbpedia.org/ontology/>
PREFIX      dbpprop:  <http://dbpedia.org/property/>
SELECT  ?name 
        ?meaning
  WHERE 
    {
      ?s                a  dbpedia-owl:Name
       ;     dbpprop:name  ?name 
       ;  dbpprop:meaning  ?meaning 
       .  FILTER (str(?name) = "Victor")
    }

Or, if you want RDF triples, use a CONSTRUCT query: 

PREFIX  dbpedia-owl:  <http://dbpedia.org/ontology/>
PREFIX      dbpprop:  <http://dbpedia.org/property/>
CONSTRUCT { ?s  dbpprop:meaning  ?meaning }
WHERE 
  {
    ?s                a  dbpedia-owl:Name 
     ;     dbpprop:name  ?name 
     ;  dbpprop:meaning  ?meaning 
     .  FILTER (str(?name) = "Victor")
  }

I think that the FOAF vocabulary is mostly suitable for describing individual persons, organizations, documents, and so on, rather than more abstract concepts like meanings of names, so this is just using the original DBpedia vocabularies.
