 ```Simon gives one example, rdfs:subPropertyOf.    (01) Other uses are: * inverseRelation ; A(X Y) <=> B(Y X) * generalizedInverse ; A(X Y) => B(Y X) * disjointPredicates * owl:equivalentProperty * negationPredicates ; ~( A(X Y) & ~B(X Y)) * negationInverse ; ~( A(X Y) & ~B(Y X))    (02) Subproperties of subPropertyOf can be useful: * transitiveClosure * properVersionOfReflexivePredicate ; e.g. properVersionOfReflexivePredicate(greaterThan greaterOrEqual)    (03) For special cases, they are also useful. * prospectiveRoles ; e.g. prospectiveRoles(dropperOf breakerOf)    (04) Say one has predicates for positions in an organization. One could relate these predicates by higher rank in the organization:    (05) * higherRankingPosition; higherRankingPosition( presidentOf vicePresidentOf)    (06) -- doug foxvog    (07) On Thu, June 12, 2014 14:18, Simon Spero wrote: > rdfs:subPropertyOf ? > On Jun 12, 2014 2:05 PM, "Frank Guerino" wrote: > >> Hi Phil, >> >> You wrote: "Will a predicate C be able to link two nodes A and B that >> may >> themselves be predicates?" >> >> I can't see (and maybe it's just because I haven't come across a >> tangible >> example) where a Predicate can cleanly link two other Predicates >> together. >> >> As of now, we follow a simple rule that uses basic sentence structure to >> validate the integrity of the Relationship.
