RDF<\/span><\/h1>\n

RDF (Resource Description Framework) is a data model designed to represent information about resources on the web. It was standardized by the World Wide Web Consortium (W3C) and uses directed graphs to organize knowledge in a structured and meaningful way. It is written in XML, and was designed to be machine-readable rather than easy for humans to read.<\/span><\/p>\n

RDF is based on the idea of making <\/span>statements<\/b> about <\/span>resources<\/b> in the form of <\/span>triples<\/b>. Each triple consist of three parts:<\/span><\/p>\n

    \n
  1. Subject<\/b>: The resource being described, usually identified by a Uniform Resource Identifier (URI).<\/span><\/li>\n
  2. Predicate<\/b>: The property that defines the relationship between subject and object.<\/span><\/li>\n
  3. Object<\/b>: The resource that the subject is related to.<\/span><\/li>\n<\/ol>\n

    RDF is specialized in linking data across the web. By using URIs, RDF enables different systems to share and understand the same data and refer to the same entities.<\/span><\/p>\n

    RDF refers to the abstract model to describe data, and it has several serialization formats, or specialized file formats in which the data can be stored. The way resources or triples are encoded can differ across formats, as well as their degree of human-friendliness.<\/span><\/p>\n

    It is expected that RDF applications will always be able to deal with the serialization formats listed as preferred formats below.<\/span><\/p>\n
