@Scott: The article is part of an ebook by O'Reilly called Graph Databases. 
It's available for free from http://neo4j.com/books/graph-databases/

I think you might be misunderstanding my objective. Person and Contact both 
extend V, and each contains appropriate properties for their respective 
objects. The example is overly simplified (and I wouldn't actually do this 
in practice), but the question is about the edges and whether it's better 
to have multiple edge classes or one edge class that has a property that 
identifies the "type" of contact. I think both approaches will work, I'm 
just looking for input on the pros/cons of each.
