1. Get all the properties that can be applied to instances of the Politician class ()

SELECT DISTINCT ?property WHERE {
?instance a <http://dbpedia.org/ontology/Politician> .
?instance ?property ?value .
}

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

SELECT DISTINCT ?property WHERE {
?instance a <http://dbpedia.org/ontology/Politician> .
?instance ?property ?value .
FILTER(?property != rdf:type)
}

Link to result:

3. Which different values exist for the properties, except rdf:type, of the instances of the Politician class?

SELECT DISTINCT ?property ?value WHERE {
?instance a <http://dbpedia.org/ontology/Politician> .
?instance ?property ?value .
FILTER(?property != 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 ?value
WHERE {

?instance ?property ?value .
FILTER(?property != rdf:type)
}
LIMIT 100

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 ?property (COUNT(DISTINCT ?value) AS ?count) WHERE {

?instance ?property ?value .
FILTER(?property != rdf:type)
}
GROUP BY ?property
