Re: Wikidata export in RDF

Hi Denny,

I have been looking for the motivation of this work on your page [1]. I 
guessed that your main goal was trying to express facts about the same 
entity but coming from different perspectives and sources? Did you get 
all of these diverse facts from wikipedia? It will be nice to have one 
step further provenance statements than just saying "Method 
Extrapolation" or "as of 15th century".

The patterns you used here are highly related to PROV [2,3], 
particularly the bundle and qualification structure of the latest PROV 
data model. Please do not hesitate to ping us if you find any 
impracticality or even problems in the current model. We will really 
appreciate your feedback!

Good work!

Cheers,

Jun
