- W3C Resource Description Framework
Resource Description Framework (RDF) describes any object as a collection of triples, each consisting of a subject, a predicate and an object. The predicate (also called a property) denotes the relationship. More details (definition, syntax, tutorials) are available at W3C site and elsewhere online.

Resources are described in terms of properties and property values using RDF statements. Statements are represented as triples, consisting of a subject, predicate and object. [S, P, O]
- Data model
- RDF is a data model, not format
The data model consists of objects and their relationships. Objects are modeled in RDF as Classes (rdf:Class), and Classes have specific Instances. Relationships are modeled with Properties (rdf:Property).
- Formats (serialization)
- Once a data model is defined, it could be serialized into different formats:
- Web Ontology Language OWL
- SPARQL Query Language for RDF
