?ins ?p ?o.
}

2. Get all the properties, except rdf:type, that can be applied
to instances of the Politician class

SELECT distinct ?p WHERE {
?ins a <http://dbpedia.org/ontology/Politician>.
?ins ?p ?o.
FILTER (?p!=rdf:type)
}

resultado

3. Which different values exist for the properties, except
rdf:type, of the instances of the Politician class?
SELECT distinct ?o WHERE {
?ins a <http://dbpedia.org/ontology/Politician>.
?ins ?p ?o.
FILTER (?p!=rdf:type)
}

4. For each of the properties, except rdf:type, that can be
applied to instances of the Politician class, which different
values do they take in those instances?

SELECT distinct ?p ?o WHERE {
?ins a <http://dbpedia.org/ontology/Politician>.
?ins ?p ?o.
FILTER (?p!=rdf:type)
}

resultado

5. For each of the properties, except rdf:type, that can be
applied to instances of the Politician class, how many
distinct values do they take in those instances?

SELECT DISTINCT ?p COUNT(DISTINCT ?o) WHERE {
?ins a <http://dbpedia.org/ontology/Politician>.
?ins ?p ?o.
FILTER (?p!=rdf:type)
}
