RDF Rules

RDF uses web identifiers (URIs) to identify resources.

RDF uses properties and property values to describe resources.

RDF Resources, Properties, and Property Values

RDF uses web identifiers to identify things and describes resources through properties and property values.

Explanation of resources, properties, and property values:

• Resource is anything that can have a URI, such as "https://www.tutorialpro.org//rdf"

• Property is a resource with a name, such as "author" or "homepage"

• Property value is the value of a property, such as "David" or "https://www.tutorialpro.org/" (Note that a property value can be another resource)

The following RDF document can describe the resource "https://www.tutorialpro.org//rdf":

RDF Statements

The combination of resource, property, and property value forms a statement (referred to as the subject, predicate, and object of the statement).
