Your mention of n-ary relations and queries caught my attention.  The 
github page describes this as "a Turtle-based syntax", but 
the example given doesn't look like Turtle:

   @prefix foaf: <>.
   foaf:knows(_:alice, _:bob).
   foaf:knows(_:bob, _:alice).

And this example is also described as being "a SPARQL-based syntax", but 
it doesn't look to me like SPARQL:

   PREFIX foaf: <>
   SELECT ?name ?mbox
       foaf:name(?x, ?name).
       foaf:mbox(?x, ?mbox).

Can you clarify?  Are you defining extensions of the Turtle and SPARQL 
syntaxes?  And if so, are these extensions only intended to address 
n-ary relations, or are you also adding more extensions for other 

I noticed mention of "formulas", which immediately made me think of n3. 
  How do your formulas differ from n3 formulas?

I also noticed mention of both "pull- and push-based querying".  How 
does that differ from forward and backward chaining?
