Some objects in Resource Description Framework (RDF) statements do not refer to other resources with a Uniform Resource Identifier (URI), but instead convey a value, such as text, a number, or a date. These objects are known as literals.

There are two types of literals:

  1. Plain literals: strings with a language tag
  2. Typed literals: strings with a datatype URI reference
