Depends on the perspective. The predicate will always be an IRI. The object will either be an IRI or a literal, and all literals in RDF (as of RDF 1.1) are typed , though serialization formats like Turtle work with implied types. There is also the option of blank nodes for objects, though in almost all implementations they are stand-ins for anonymous IRIs, so in some sense or another almost anything has "a" type.
