    3737==== RDF ==== 
    38 [http://www.w3.org/RDF/ RDF] assumes that anything in the world can be described in triples, i.e. statements consisting of subject, predicate, object. [http://www.w3.org/TR/rdf-syntax-grammar/ RDF/XML] is just one serialization of the concept of triples (other ways are M3, [http://www.json.org/ JSON], [http://www.w3.org/TR/rdfa-syntax/ RDFa] etc.). An RDF/XML document imports at least two namespaces: rdf and [http://www.w3.org/TR/rdf-schema/ rdfs].

[http://www.w3.org/TR/rdf-syntax-grammar/ RDF/XML] is just one serialization of the concept of triples (other ways are [http://www.w3.org/DesignIssues/Notation3 N3], [http://www.json.org/ JSON], [http://www.w3.org/TR/rdfa-syntax/ RDFa] etc.).

    3939 * Simple example: rdf:Description element defines the subject, rdf:about attribute defines a resource that is the subject. rdfs:label, for example, attaches a human readable label to a subject. 
    4040 * Example with more namespaces: subject is now defined on element foaf:Person (again by rdf:about), subject has multiple predicates: foaf:name (his name), foaf:page (which in turn encloses another triple: foaf:Document => dc:title => literal)
