Именованный граф — graph dataset или subgraph, идентифицируемый отдельным name или URI, обычно используемый в semantic web и RDF systems. Он позволяет группировать, referenced, queried и managed statements как конкретный graph внутри более крупной knowledge base.
A key concept of Semantic Web architecture in which a set of Resource Description Framework statements (a graph) are identified using a URI, allowing descriptions to be made of that set of statements such as context, provenance information or other such metadata. Named graphs are a simple extension of the RDF data model through which graphs can be created but the model lacks an effective means of distinguishing between them once published on the Web at large.
