RDF (Resource Description Framework)
RDF, which stands for Resource Description Framework, is a standard model for representing and exchanging data on the web. It is a W3C recommendation used to describe resources in a machine-readable format. RDF provides a framework for expressing metadata, relationships, and semantics about resources on the web. It uses triples to represent data, consisting of subject-predicate-object statements, where the subject is the resource being described, the predicate is the property or attribute of the resource, and the object is the value of that property. RDF is commonly used in linked data applications, semantic web technologies, and knowledge representation systems to enable interoperability and integration of data from different sources. It forms the basis for various data formats and vocabularies, including RDF/XML, Turtle, JSON-LD, and OWL (Web Ontology Language), facilitating the exchange and reuse of structured data across the web.
