The Resource Description Framework (RDF) is a standard developed by the World Wide Web Consortium (W3C) for describing and exchanging data on the web. It’s designed to represent information about physical objects and abstract concepts, and to express relationships between entities using a graph data model.
For example, an RDF description of a book might include information such as its title, author, publication date, and subject matter. This data can be linked together using RDF syntax to form a network of interconnected data that can be shared and reused across different applications and platforms.
