[Data-modeling] surprised that I could assign properties without also typing an object with the property's parent type

Yes, MQL does not enforce that an object is typed any particular way.  
The type system is non-normative.
Sometimes we refer to this feature as "bare properties" that you can  
have any specific property regardless of your types.

The freebase.com application will assert a type on the target topic  
when you enter a topic value in a property field.  It does this by  
using the expected_type property of /type/property to figure out what  
the destination type should be.  MQL is acting at a lower level and  
does not enforce that.
