document: Named graphs , provenance and trust The Semantic Web consists of many RDF graphs nameable by URIs . This paper extends the syntax and semantics of RDF to cover such Named Graphs . This enables RDF statements that describe graphs , which is beneficial in many Semantic Web application areas . As a case study , we explore the application area of Semantic Web publishing : Named Graphs allow publishers to communicate assertional intent , and to sign their graphs ; information consumers can evaluate specific graphs using task-specific trust policies , and act on information from those Named Graphs that they accept . Graphs are trusted depending on : their content ; information about the graph ; and the task the user is performing . The extension of RDF to Named Graphs provides a formally defined framework to be a foundation for the Semantic Web trust layer .
