The Provenance Ontology supports data management and auditing tasks. It is used by the BBC to define the different types of named graphs used in the store (quad store) and enables their association with metadata that allows them to manage, validate and expose data to their services. This provenance is focused on the immediate providers and not the ultimate source, so for example, this would record that geodata was provided by the BBC Locator team, and not geonames. In the Linked Data Platform, this data is applied to contexts or named graphs. A named graph is, in effect, a 'fourth part' to a triple, hence the term 'quad store'.
