• Live-edited the item about Nobel laureate Barbara McClintock [2]
  
  
• Saw how Wikidata is used in Histropedia [3]
  
  
• Discussed instance of (P31), subclass of (P279), and part of (P361) and how to avoid "bad smells" [4]
  
  
• Learned about the RDF/OWL exports and how to explore them locally with Protege [5]
  
  
• Talked about modeling causation on Wikidata, in the context of the American Civil War [6]
  
  
• Covered Wikidata vocabulary, the Wikidata API, where to find things, unit quantity properties (e.g. area, length, GDP per capita), etc.
  

I'd estimate we had 30 to 40 attendees. 

Later the same day, Katie (Aude) presented on integrating Wikidata into Wikipedia through Lua.  Elvira (Emitraka) also presented on how the Gene Wiki project has been enhancing Wikidata with items about genes, items about diseases, and their causal connection -- and how the Gene Wiki group is working to make corresponding infoboxes on Wikipedia more relevant to the layperson.  Both talks were well-attended and excellent.

Cheers,
