Last updated: 2026-04-18
The semantic web is built on the idea that data should be published in standardized, interlinked formats that describe its meaning.
Core Technologies
- RDF (Resource Description Framework): A model for representing data as “triples” (subject, predicate, object) (source: chapter2, p. 59).
- SPARQL: A declarative query language for RDF triple-stores (source: chapter2, p. 59).
- Ontologies: Formal vocabularies for describing the entities and relationships in a specific domain.
Practical Status
While the full vision of the semantic web has not yet been realized, its technologies are widely used in specialized fields like bio-informatics and for publishing structured data (e.g., Schema.org).
