Hi all,

we are trying to analyze datatype properties by the datatype they use. 
Our first idea was to use a simple SPARQL query per property, however, 
the following does not do what I would expect it to do:

SELECT COUNT(?x) DATATYPE(?y) WHERE {?x dbpprop:utcOffset ?y}

This query does not group all entries with, e.g., 
<http://www.w3.org/2001/XMLSchema#int> in one row. Why not? What am I 
doing wrong here?
