i'm not sure how interpret semantics of following rdf triples. interpreting them correctly? example a subject - predicate - object tom - age - 24 i read predicate age has value 24. seems unintuitive. however, can read 24 related tom predicate age makes better semantic sense me. example b subject - predicate - object tom - hasproperty - age age - hasvalue - 24 this conveys age property of tom. value of property 24. makes explicit how age relates tom. in 1 example, age predicate, in other example, object. in both cases information encoded more or less same addition of explicit property in example b. yes, interpreting them correctly. both examples encode same information (namely age of tom 24). in first example, done via direct binary relation. rewritten in first-order predicate logic reads: age(tom, 24) in second example, relation has been reified object, , reads hasproperty(tom, age) hasvalue(age, 24)
