RDF

RDF (Resource Description Framework) is a standard data model. It basically builds on anything being expressed as triples, i.e. statements of the form subject - predicate - object. An example is

<http://example.org/id/John> <http://example.org/id/Has_wife> <http://example.org/id/Mary>

saying that John has Mary as a wife (or, more exactly, that the property holds between the subject and the object).
