RDF Triples

A standardized data model that represents semantic statements as subject-predicate-object expressions, forming the fundamental building blocks of the Semantic Web.

RDF Triples

RDF (Resource Description Framework) triples are fundamental units of knowledge representation that express semantic relationships in a machine-readable format. Each triple consists of three components: subject, predicate, and object, forming atomic statements about resources and their relationships.

Core Structure

Components

  1. Subject: The entity or resource being described
  2. Predicate: The property or relationship type
  3. Object: The value or related entity

Example Expressions

<Person:JohnDoe> <hasAge> "30"
<Book:Hamlet> <hasAuthor> <Person:WilliamShakespeare>
<Planet:Earth> <isPartOf> <SolarSystem:MilkyWay>
