Representation of database record subjects (a/k/a keys, IDs, entities), predicates (a/k/a columns, attributes), and objects (a/k/a values) as triples, where the first two are always URIs, and the third is either a URI or a literal; enabling humans and machines to more easily share, merge, and evaluate data from heterogeneous origins.
The Semantic Web (Web 3.0) provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries. It is a collaborative effort led by the W3C with participation from a large number of researchers and industrial partners. It is based on the Resource Description Framework (RDF).
