RDF (Resource Description Framework) is a framework that enables the construction of structured data endowed with human and machine comprehensible entity relationship semantics. It makes this possible by providing a Language (system of Signs [IRIs], Syntax [Subject, Predicate, Object relationship roles], Semantics [First-order Logic], and Statements [Subject→Predicate→Object]) for expressing, representing, serializing, and publishing entity relationships in digital form. In usage patterns where IRIs take the form of HTTP URIs, the end product is a public or private Linked Data Network (Cloud) endowed with machine and human comprehensible entity relationship semantics. In the context of the World Wide Web, RDF enables the construction of a Semantically enhanced Linked Open Data abstraction which is commonly referred as 'The Semantic Web'.
