Data

@prefix foaf: <http://xmlns.com/foaf/0.1/> .

<http://www.learningsparql.com/ns/demo#i93234>
    foaf:nick "Dick" ;
    foaf:givenname "Richard" ;
    foaf:mbox "richard49@hotmail.com" ;

Query

PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

SELECT ?propertyLabel ?value
WHERE
{
    ?s ?property ?value .
    ?property rdfs:label ?propertyLabel .
}

Result

The first triple pattern asks for all triples, because all three parts of the triple pattern are variables. The second triple pattern binds rdfs:label values associated with the ?property values from the first triple pattern to the ?propertyLabel variable. The SELECT list asks for these ?propertyLabel values, not the URIs that represent the properties, and the ?value values.
