Hoi,
To confuse you even more, Reasonator knows about Wikipedia categories. What
is so exciting is that it is possible to include statements in Wikidata
that Reasonator interprets as statements for a query. Reasonator shows you
the results from that query.
I blogged about a Mr Sinegal [1], in the article are links that include
numbers, they show off that these queries are live and will show new
numbers when either US musicians or musicians are added in Wikidata.
Thanks,
GerardM
PS I am harvesting information at this time, so you will see updates more
or less every fifteen minutes.
