relation p is the direct form of relation q iff p is a subPropertyOf q, p does not have the Transitive characteristic, q does have the Transitive characteristic, and for all x, y: x q y -> exists z1, z2, ..., zn such that x p z1 ... z2n y

editor note

The general property hierarchy is: "directly P" SubPropertyOf "P" Transitive(P) Where we have an annotation assertion "directly P" "is direct form of" "P"

logical macro assertion on an annotation property

If we have the annotation P is-direct-form-of Q, and we have inverses P' and Q', then it follows that P' is-direct-form-of Q'
