 Got it.  Thank you.Frank -- Frank Guerino, Chairman The International Foundation for Information Technology (IF4IT) http://www.if4it.com 1.908.294.5191 (M)From: Philip Jackson Reply-To: "[ontolog-forum]" Date: Friday, June 13, 2014 8:27 AMTo: Frank Guerino , "[ontolog-forum]" Subject: Re: [ontolog-forum] Requesting Opinions on the Benefits of Predicates as NodesHi Frank, Using your terms and interpretation, I would say the statement "X says (Y causes Z)" is the latter, i.e. stating a unique relationship between X and  the unique relationship "Y causes Z". As you know, separately Simon Spero  and Doug Foxvog gave examples of general relationships between relationships: Simon: "is a sub property of" is a sub property of "is a specialization of".  (a nice recursion!) Doug:  properVersionOfReflexivePredicate(greaterThan greaterOrEqual)prospectiveRoles(dropperOf breakerOf)higherRankingPosition( presidentOf vicePresidentOf) My example and question was motivated by what Jack Park wrote in his first message in this thread: if a specific *instance* of a predicate exists as a connective between two objects, then it can be said to carry thefull semantics of the assertion itself. The instance is not an 'implicit' node: it is a vertex like any other in a graph. If I say: A cause B, then the node which is the 'cause' predicate can carry the full semantics of the triple itself. It's not just your father's predicate anymore; it's a first class citizen. Why do I care? Consider that said predicate has entails a possibly complex biography. Who discovered it? What evidence supports it? What debates are in play about it? Hence my disclaimer that I was only asking a question, not claiming a proof of what should be in the IF4IT standard, since the question revolves on how the standard defines the term "predicate"... My Best, Phil
