This paper addresses the question, "Is RDF a Framework, Data Model or Vocabulary?" The author argues that RDF is simultaneously a framework, data model and basis for building more complex vocabularies; it is both simple and complex at the same time. The author lists his "Top Sixty Benefits of RDF".

- Articulates differences between the RDF abstract data model and the XML and relational models.
- Knows the subject-predicate-object component structure of a triple.
- Understands that URIs and literals denote things in the world ("resources") real, imagined, or conceptual.
- Differentiates hierarchical document models (eg, XML) and graph models (RDF).
- Distinguishes the RDF abstract data model and concrete serializations of RDF data.
- Knows that the word "ontology" is ambiguous, referring to any RDF vocabulary, but more typically a set of OWL classes and properties designed to support inferencing in a specific domain.
- Uses RDF Schema to express semantic relationships within a vocabulary.
