A named graph is a concept in the Semantic Web architecture where a set of Resource Description Framework ( RDF ) statements (a graph) are identified using an internationalized resource identifier ( IRI ). This allows for descriptions to be made about that set of statements, such as context, provenance information, or other metadata. In an RDF database, a named graph is essentially a subset of data that has been given a unique label (referred to as a name). A graph database can contain multiple named graphs alongside its default graph, and each fact can be present in or absent from any graph. Named graphs form a patrician of information that can be used. Named graphs are useful for managing sets of RDF data within an RDF store, enabling fine-grained access control, and managing chains of provenance for pieces of data.
