Hi Phil,
Thanks for the clarification. If you don't mind, I have a follow-up question on the example you provided…
You wrote: "another example could be "X says (Y causes Z)", i.e. a predicate C could link two nodes A and B, where A or B may be a predicate, though not necessarily both."
In this example, my interpretation is that… - X, Y, and Z are atomic Nodes
- "says" and "causes" are atomic Predicates
- (Y causes Z) is a Relationship statement
In the statement: "X says (Y causes Z)", is it really that a Predicate ("says") is linking to another Predicate OR is it that the second Predicate ("says") is linking a Node ("X") to an entire and very unique Relationship statement ("Y causes Z")?
My Best,
Frank

Hi Frank,
I asked the question in response to Jack Park's email, in which he suggested a predicate instance could be a verb relating a subject and object, e.g. "X causes Y". If this can be a first-class entity then it seems another example could be "X says (Y causes Z)", i.e. a predicate C could link two nodes A and B, where A or B may be a predicate, though not necessarily both. Separately, Doug Foxvog and Simon Spero gave examples where both A and B are predicates, linked by a predicate C.
However, I was just asking a question, and suggesting this could be useful, not claiming to have a proof of what is or should be supported in the IF4IT standard.
Best,
Phil
