What is RDF?
what is RDFRDF (Resource Description Framework) is a W3C standard for representing information as a set of statements called triples. Each triple consists of a subject, predicate, and object - for example, “London — isCapitalOf — United Kingdom”. By giving every entity and relationship a unique URI, RDF makes data globally unambiguous, linkable, and machine-readable.
Why It Matters for Enterprise
Most enterprise data is trapped in format-specific silos - relational tables, JSON APIs, XML feeds, CSV exports. RDF provides a universal data model that can represent information from any source in a consistent way, making it the lingua franca for data integration.
Because RDF uses URIs as identifiers, data from different organisations can be merged without naming collisions. This is why RDF underpins global data-sharing initiatives in finance (FIBO), government (linked open data), and science (biomedical knowledge graphs).
RDF is also the foundation of the semantic web stack: combined with ontologies (OWL/RDFS), shape constraints (SHACL), and query languages (SPARQL), it forms a complete platform for building intelligent, interoperable data systems.
How It Works
An RDF statement (triple) has three parts:
Subject: The thing being described, identified by a URI (e.g., ex:London).
Predicate: The property or relationship, also a URI (e.g., ex:isCapitalOf).
Object: The value - either another URI (e.g., ex:UnitedKingdom) or a literal (e.g., "8,799,800"^^xsd:integer).
RDF can be serialised in several formats: Turtle (human-friendly), JSON-LD (web-friendly), N-Triples (simple, line-based), and RDF/XML (legacy). The underlying data model is the same regardless of serialisation.
RDF data is stored in a triplestore - a database optimised for graph queries. Triplestores support SPARQL, the standard query language for traversing and manipulating RDF graphs.
Real-World Examples
Wikidata: The structured knowledge base behind Wikipedia stores billions of RDF triples about people, places, organisations, and events. It is freely queryable via a public SPARQL endpoint.
European data portals: EU member states publish government datasets as linked RDF data using the DCAT vocabulary, enabling cross-border discovery and integration.
Enterprise data integration: A pharmaceutical company converts clinical trial data, compound libraries, and regulatory submissions into RDF, enabling scientists to query across previously siloed systems with a single SPARQL query.
