Ok,
Thank you Kingsley. As test I searched for a property to describe
valuta (USD, Euro);

    select ?s1p as ?c1 count (*) as ?c2  where { ?s1 ?s1textp ?o1 .
?o1 bif:contains  '"Valuta"'  .?s1 a
<http://www.w3.org/2000/01/rdf-schema#Property> . ?s1 ?s1p ?s1o . }
group by ?s1p order by desc 2 limit 20  offset 0

Zero results unfortunately ;) But this says more about this particular
property than this great service ?

Greets,
Martijn
