Review of Resource Description Framework (RDF)

Nowhere in this article do you mention what an RDF graph is. I think you should do this. You can then say that an RDF graph is a set of triples where each triple is a statement with a subject, predicate object.

There are no links to the RDF specs or docs. Same for RDF/XML, Turtle, N3 etc.

There is nothing about querying RDF graphs with SPARQL in this article. There should be.

The paragraph about OWL seems poor. “Other schemas can be built on top of RDF and RDFS, one popular example is the Web Ontology Language (OWL), which provides a rich set of vocabularies with a precise and well defined semantics for building Ontologies”. I would replace all of this with something like “OWL ontologies can be serialised into an RDF graph”.

You don’t have any criticisms about RDF, its serialisations or anything like that. I think you should.

The formatting needs much improvement. Put your examples in a pre tag.
