I've wondered for years about the analogy between RDF and the 
binary-relational model (cf 
http://www.dbdebunk.com/page/page/1147347.htm) in which everything is 
modeled as two entities with a relationship between them  There's also 
variants such as the Associative Model of Data 

As Dare implies, there has got to be some sort of mapping between the 
abstraction of triples / binary relations and actual application data.  
Of course that's true with raw XML or the n-ary relational model, but 
triples seem to be a pretty abstract abstraction, and it sounds like 
this is one reason why the binary relational approach hasn't taken off.

I just wonder whether RDF advocates are aware of these other 
triples-like approaches, what they think they've learned from them, or 
whether they think the analogy is misleading?
