RDF data consists of statements with a subject, object, and a relationship between them.
Any language capable of expressing this simple form can be an RDF language.
Several languages have emerged with different specialities:
<rdf:Description rdf:about="http://purl.org/dc/elements/1.0/title"> <renderedAs> <rdf:Description> <http:ContentLength>17056</http:ContentLength> </rdf:Description> </renderedAs> </rdf:Description>
dc:title renderedAs [ http:ContentLength "17056" ] .
<http://purl.org/dc/elements/1.0/title> <renderedAs> _:1 . _:1 <http://www.w3.org/1999/xx/ns#ContentLength> "17056" .
'((renderedAs dc:title ?thingy) (http:ContentLength ?thingy "17056"))
