Hoi,
One of the things Reasonator does not do is provide information on qualifiers. I am interested particularly in Q2354820 and where it is used.

I take it that SparQL supports such a query. Could somebody provide me with a query that does exactly this? 

<grin> it would be the first time that I actually have a use beyond Resonator. </grin>
Thanks,
