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!

Essentially, if there is a property 'p' then the 'qualifiedP' is another property whose range is an object of a specific type that has the other information.
