Anyway it doesn't hurt to clarify whether RDF actually holds any meaning for triples. I always presumed that was part of the vocabularies and not part of RDF.
RDF is a language, thus it is comprised of the following: 1. signs -- for entity denotation (in this case IRIs)2. syntax -- constructing statements that represents entity relationships (in this case subject, predicate, object, triple patterns) 3. semantics -- for understanding the meaning of different types of relationships (in this case the meaning of the subject, predicate, and object relationship roles).
A language is a framework for encoding and decoding information. This is what RDF is all about. 2 out of 3 (above) isn't RDF it has to be all three, since it's a language.
What can make RDF confusing is the fact that you can create RDF document content using a variety of notations or so called "concrete syntaxes" (N-Triples, Turtle, RDF/XML, JSON-LD, HTML+RDFa, HTML+Microdata etc..).
I hope this helps.
