Haasepeter added a comment. On Tuesday I had shown you some sample queries and visualizations (http://www.grapphs.com:8087) based on the unqualified/simple RDF statements of the Wikidata RDF export. The question came up how to query the qualified statements. I have also loaded the qualified statements from http://tools.wmflabs.org/wikidata-exports/rdf/exports/20150126/ As an example, please see http://www.grapphs.com:8087/resource/Q42 that answers the question from above "give me all data about Douglas Adams (Q42) that came from Encyclopædia Britannica Online (Q5375741)".
Note that the join conditions become rather difficult because of the peculiar reification model chosen by the wikidata RDF export. This can be done more compact using RDR.
