RDF is a framework for semantic descriptions of resources that can
be referenced by URI. It represents information about resources in
form of a graph with directed labeled edges. Or told otherwise, as
a set of triples which consist of a subject a predicate and an
object. The point behind the whole thing is that computers can
partially understand and process this information. This makes it
possible for a search engine to answer a question as for example
"Give me all Italian musicians from the 18th century". Answering
such a question is not possible by simple text matching methods, as it
involves a deeper understanding of the semantics. Indeed, RDF is
the basic framework of the semantic web.
