The RDF data model represents information as triples of subject, predicate and object, forming a directed labelled graph. It is the foundation of the Resource Description Framework used to publish structured data on the web.
Semantic Classification
Content
- The RDF data model expresses every statement as a triple linking a subject to an object through a predicate, where resources are identified by URIs. A set of triples forms a graph that can be merged with other graphs sharing the same identifiers.
- Because the model is graph-based and uses global identifiers, data from different sources combines without a fixed schema. It is queried with SPARQL and provides the substrate for linked data and knowledge graphs on the semantic web.
