Resource Description Framework (RDF)

The Resource Description Framework (RDF) provides a simple way to describe resources on the web. It is a directed, labeled graph data format for representing information in the Web.

Knowledge is represented as assertions (or triples) of the form:
URI — property — value
where 'URI' is the URI of the thing being described, 'property' is (the URI of) a property, and 'value' is the value that that property can take, either another URI, a literal string, or a chunk of XML.

See RDF in Drupal: Super-Simple Primer for a quick overview and the RDF Primer for an in depth tutorial.
